Easy TwinLong division: how to help your child practice
Long division breaks a big division problem into a repeating cycle of small steps: divide, multiply, subtract, bring down, then check by multiplying. Most US schools start with 1-digit divisors in 4th grade, move to 2-digit divisors in 5th grade, and expect fluency with the standard method in 6th grade.
What is long division?
Long division is a way to divide large numbers one place at a time. Instead of solving 852 ÷ 4 in one go, you ask a series of small questions: how many 4s in 8 hundreds, then in 5 tens, then in 12 ones.
Kids often find it hard not because any step is hard, but because there are many steps to keep in order. A solid grip on the times tables and on subtraction makes everything else easier.
In most US schools, 4th graders divide numbers up to four digits by 1-digit divisors (often with area models or partial quotients first), 5th graders divide by 2-digit numbers, and 6th graders are expected to use the standard algorithm fluently. For a longer walkthrough with pictures, read long division, step by step, and see the division topic guide for how it builds from simple sharing.

How do you do long division, step by step?
Repeat one cycle until there are no digits left to bring down. Many kids remember the order as "Dad, Mom, Sister, Brother": Divide, Multiply, Subtract, Bring down. Here is 852 ÷ 4:
- Divide. How many 4s in 8? 2. Write 2 above the 8.
- Multiply. 2 × 4 = 8. Write 8 under the 8.
- Subtract. 8 − 8 = 0.
- Bring down the next digit, 5. Now divide again: 4 goes into 5 once. 1 × 4 = 4, 5 − 4 = 1. Bring down the 2 to make 12.
- Repeat. 4 goes into 12 three times. 3 × 4 = 12, 12 − 12 = 0. Nothing left to bring down, so the answer is 213.
- Check. 213 × 4 = 852. It matches.
If the last subtraction leaves something, that's the remainder. 157 ÷ 6 = 26 R1, because 26 × 6 = 156 and 157 − 156 = 1. The remainder must always be smaller than the divisor.
What long division mistakes do kids make most?
Leaving out a zero in the answer
For 624 ÷ 6, a child gets 14. After 6 goes into 6, the 2 is too small to divide, so they skip it. But that place still needs a digit: 6 goes into 2 zero times. The answer is 104. Checking by multiplying (14 × 6 = 84) shows right away something is off.
A remainder bigger than the divisor
A child answers 157 ÷ 6 with 25 R7. Since 7 is more than 6, another group of 6 fits. The answer is 26 R1. Make "Is my remainder smaller than the divisor?" part of every check.
A small subtraction slip
Solving 952 ÷ 7, a child gets 25 − 21 = 3 instead of 4, and ends up with 134 R4. The answer is 136. Checking catches it: 134 × 7 + 4 = 942, not 952. Encourage your child to check every problem by multiplying back.
How can you practice long division at home in 10 minutes?
Long division needs focus, so fewer problems done carefully beat a long page done fast.
- Minutes 1–2: warm up the facts. Ask five quick division facts using the divisor of the night: 24 ÷ 6, 42 ÷ 6, 54 ÷ 6, 36 ÷ 6, 48 ÷ 6.
- Minutes 3–8: three problems. One with no remainder (936 ÷ 6), one with a remainder (437 ÷ 6), and one that needs a zero in the answer (624 ÷ 6). 5th and 6th graders can swap one for a 2-digit divisor (672 ÷ 16).
- Minutes 9–10: check by multiplying. Your child multiplies each answer by the divisor (and adds any remainder) to see if it lands on the original number.
Use different divisors on different nights so all of the times tables get a workout.

Frequently asked questions
What grade learns long division?
Most US schools start long division with 1-digit divisors in 4th grade and move to 2-digit divisors in 5th grade. By 6th grade kids are usually expected to use the standard method fluently.
What are the steps of long division?
The steps are divide, multiply, subtract and bring down, repeated until no digits are left. Then check by multiplying the answer by the divisor and adding any remainder.
Why does my child's school teach division differently?
Many schools teach partial quotients or area models before the standard method because they show why division works. Both give the same answer, and kids who understand the model usually pick up the standard method more easily.
My child knows the steps but still gets wrong answers. Why?
Usually it's a shaky times-table fact or a subtraction slip, not the method. Have your child check each answer by multiplying, and practice the facts for the divisors that keep causing trouble.

Long division at home: a step-by-step guide for parents
Long division is the same five steps repeated (divide, multiply, subtract, check, bring down) until there are no digits left, and a child who knows their multiplication facts can learn it in a couple of weeks of short practice. This guide walks through two fully worked examples, the partial-quotients method many schools teach first, the six most common mistakes, and a 10-minute-a-day plan.
How to Help With Math Homework When It's Taught Differently Than You Learned It
To help with math homework that's taught differently than you learned it, use the method printed on the page, ask your child to teach it to you, and find the worked example from class before you show your own way. Schools teach place-value strategies first so children understand why the steps work, and the standard algorithm usually follows a grade or two later. This guide shows side-by-side examples, what to say when you're stuck, and when to email the teacher.
