A short lesson on how to do long division, in three sheets. The first shows the four steps one at a time on a single problem, then remainders and the zero mistake. The second is guided practice that starts with the first round of steps already done. The third is practice on its own, with every line of work shown in the answer key.

Divide, multiply, subtract, bring down: each step shown on the same problem. Plus remainders and how to check.

Twelve problems, a word problem with a remainder, and one mistake to explain. The key shows every line of work.
Download PDFLong division is four small steps done in the same order again and again: divide, multiply, subtract, bring down. Each step on its own is something a 4th grader already knows how to do. What makes long division hard is keeping track of where you are and where each digit goes.
The How It Works sheet slows that down. It shows one problem, 92 ÷ 4, five times. Each picture adds only the next thing to write, in a different color, with one sentence about it. After the four steps the fifth picture repeats them to finish the problem.
The rest of the sheet covers the three things that cause most wrong answers. There is a worked problem with a remainder, a way to check any answer by multiplying back, and the case where the divisor does not go into the number and a zero has to be written in the answer.
The guided practice sheet prints faint boxes under each problem so the digits stay in their columns, and starts the first four problems for the student. The independent practice sheet removes the boxes. For more problems after that, the long division worksheets page makes a fresh set each time, and a multiplication chart helps students who are still learning their facts.
