How to Explain Long Division to Parents (With a Letter You Can Send Tonight)

Long division is one of those topics that sends parents straight to Google at 9pm — not because their child can't do it, but because the way it's taught today doesn't match what the parent remembers from their own third or fourth grade classroom. A quick letter home gets ahead of that confusion before it becomes homework-table frustration.

Here's one you can copy, paste, and send tonight.

The Letter

Subject: Helping Your Child with Long Division at Home

Dear Families,

We've started working on long division in class this week, and I wanted to give you a quick heads-up so homework time goes smoothly.

Long division is one of those skills that looks different depending on how it's taught — and if it's been a while since you learned it yourself, the steps your child brings home may feel unfamiliar. That's completely normal.

Here's the method we're using in class, step by step:

Divide → Multiply → Subtract → Bring down

Let's walk through an example: 96 ÷ 4

1. Divide: How many times does 4 go into 9? It goes in 2 times. Write the 2 above the 9.
2. Multiply: 2 × 4 = 8. Write the 8 below the 9.
3. Subtract: 9 − 8 = 1. Write the 1.
4. Bring down: Bring the 6 down next to the 1. Now you have 16.
5. Repeat: How many times does 4 go into 16? It goes in 4 times. Write the 4. Multiply: 4 × 4 = 16. Subtract: 16 − 16 = 0.

Answer: 96 ÷ 4 = 24

A few tips for homework time:

• Don't show them a different method. Even if it gets the right answer, switching approaches mid-unit creates confusion. If you learned a shortcut, hold off until they've got this one solid.
• Let them talk through each step out loud. Saying "divide, multiply, subtract, bring down" while they work is encouraged — it keeps them on track.
• Mistakes in multiplication cause most of the errors. If the answer is off, have them check their multiplication tables first before redoing the whole problem.
• Remainders are coming soon. For now, we're working with problems that divide evenly. Remainders will be introduced once they're comfortable with the core steps.

If your child is stuck or frustrated, the best thing you can do is work through one problem together using these steps, then let them try the next one on their own. Learning to do it — not just getting the right answer — is what builds the skill.

As always, feel free to reach out if you have questions. I'd rather you email me than have your child sit through a homework session that goes sideways.

Thank you for partnering with me,

[Your name]

Why Parents Get Confused (and It's Not Their Fault)

The steps above — divide, multiply, subtract, bring down — are the standard algorithm, and they haven't changed much. What changes is the language, the layout on the page, and whether teachers emphasize estimation and place value before drilling the procedure. Some curricula also introduce partial quotients first, which looks completely different on paper but arrives at the same answer. If a parent learned partial quotients and the class is using the standard algorithm (or vice versa), one of them is going to think the other is doing it wrong. Neither is.

The letter above gives parents a clean reference for exactly what their child is seeing in class. Swap in your actual example problems if you want it to match the homework page.
