How to help your child with long division (without losing your mind)
A calm, step by step approach to teaching long division at home, with examples, common pitfalls and ready to use practice ideas.

Long division is one of those topics where kids hit a wall, and parents quietly panic because they have not done it on paper in twenty years. The good news is that the method has not changed, and once you slow it down into clear steps, most kids click within a week of regular practice.
Start by checking the building blocks
Before you touch a long division problem, make sure your child is fluent in three things: times tables up to twelve, basic subtraction with borrowing, and the idea of a remainder. If any of those wobble, long division will feel impossible. Spend a few short sessions shoring them up first. You will save hours of frustration later.
The four step rhythm: divide, multiply, subtract, bring down
The single most useful thing you can do is teach the rhythm out loud. Many teachers use the mnemonic Dad, Mum, Sister, Brother for Divide, Multiply, Subtract, Bring down. Say it together every single step. After a couple of sessions your child will start whispering it on their own, and the procedure becomes muscle memory rather than a maths puzzle.
Use squared paper
Half of long division mistakes are not maths mistakes, they are place value mistakes. Digits drift out of their columns, a one looks like it lives next to a seven, and suddenly the answer is wildly wrong. Squared paper, or a notebook with large grid squares, fixes most of this for free.
Talk through the first three problems together
For the first three problems of any session, sit next to your child and narrate every step out loud. Then hand the pencil over and let them narrate the next problem to you. Only after that should they work silently. This sounds slow, but it builds the inner voice they will rely on during a test.
Common pitfalls to watch for
- Forgetting to write a zero in the quotient when the divisor is bigger than the current digit.
- Subtracting incorrectly because the digits are misaligned.
- Bringing down the wrong digit.
- Stopping too early and leaving a remainder larger than the divisor.
When you spot a mistake, resist the urge to point straight to it. Instead, ask your child to read their work back to you, step by step, using the rhythm above. Eight times out of ten they will spot the error themselves, which is the whole point.
A simple weekly practice plan
Three short sessions a week beats one long session every time. Aim for ten minutes on Monday, ten minutes on Wednesday, and a slightly longer fifteen minute session on Saturday with two or three trickier problems. After two weeks of this, most kids move from terrified to confident. Generate a fresh maths pack at the start of each session so the questions stay novel.
When to bring in support
If your child is still stuck after three or four weeks of consistent practice, it is almost never about long division itself. Loop back to times tables, place value or subtraction, and you will usually find the real blocker hiding there.
