Long Division Calculator (with Steps)
This long division calculator lets you divide numbers step by step and see every line of work. It is a long division calculator with steps that is designed for students, parents, and teachers who want a clear way to solve long division problems, including decimals and remainders and a way to show your work for each question.
Enter the dividend and divisor to see the result and every step of the long division.
You can use negative numbers or decimals (like
-42.5).
Use any non‑zero number. We'll handle signs and decimals.
Helpful in class: enter the numbers students suggest, then talk through each step as it appears.
This view is intentionally simple so it looks like work on paper. Use the written explanation list if students need more support.
What is Long Division?
Long division is a method for dividing one number by another when the answer is not obvious. You set up the problem with the dividend (the number being divided) inside the bracket and the divisor (the number you are dividing by) on the left. Then you work from left to right, asking how many times the divisor fits into each part of the dividend. At each step you divide, multiply, subtract, and then bring down the next digit. This slow, written process turns a big division problem into several smaller and easier problems. It also makes it clear how the quotient and any remainder are formed.
How to Do Long Division Step by Step
Worked Example: 789 ÷ 4
Here is a worked example using 789 ÷ 4. First, set up the problem with 4 on the left and 789 inside the bracket. Start with the first digit: 4 goes into 7 one time, so write 1 above the 7. Multiply 1 × 4 = 4 and subtract: 7 − 4 = 3. Bring down the next digit, 8, to make 38. Now divide again: 4 goes into 38 nine times, so write 9 on top, making 19 so far. Multiply 9 × 4 = 36 and subtract: 38 − 36 = 2. Bring down the last digit, 9, to make 29. Finally, 4 goes into 29 seven times, so write 7 to get 197. Multiply 7 × 4 = 28 and subtract: 29 − 28 = 1, so the answer is 197 with remainder 1.
Long Division Calculator – Show Your Work
This long division calculator is built to show your work, not just the final answer. When you enter a dividend and divisor and press Calculate, it lays out a long division bracket and shows a clear quotient. Under the bracket, it explains each step in words so you can follow the divide, multiply, subtract, and bring down pattern. This makes it useful for checking homework, learning the standard algorithm, or showing the process on a projector in class. Students, parents, and teachers can all see exactly how the result was reached.
Long Division with Decimals and Remainders
You can use this calculator for long division with decimals and remainders. If the divisor or dividend has a decimal, the calculator lines up the decimal places the same way a teacher would do on paper. It moves the decimal in both numbers when needed and places the decimal in the answer in the correct position. When a problem does not divide evenly, the tool shows the remainder and explains what is left over. You can treat this remainder as a whole number remainder, a fraction, or continue dividing to see a decimal result, depending on what your class or homework requires. If you want a full guide, you can also see our long division with decimals calculator and our long division with remainders calculator.
Long Division for Kids and Students
This long division calculator is designed to support kids and students who are still learning the algorithm. Grade 3 students can use it to see how division is related to repeated subtraction and equal groups. Grade 4 students can check their multi-digit long division work and see each written step when they are still building confidence. Grade 5 students can use it to practice more complex problems with larger numbers, decimals, and remainders. Parents and teachers can use the step-by-step view to pause, ask questions, and explain why each move in the long division process makes sense. We also provide special versions for students, including a long division calculator for kids and tools for grade 3, grade 4, and grade 5.
