Long Division Calculator

How to use

1. 1Type the dividend (the number being divided) and the divisor (the number you divide by) into the two input fields. Commas, spaces, and underscores are ignored.
2. 2Pick an answer format: Quotient with remainder, Mixed number, or Decimal expansion (with repeating-digit detection).
3. 3Tap a Classic example chip (1234 / 7, 100000 / 23, 1 / 7, 22 / 7) to load a worked problem in one click.
4. 4Read the headline equation for the short answer, the Quotient and Remainder cards for the parts, and the Vertical layout block for the schoolbook work shown.
5. 5Scroll the Step by step list to see each partial dividend, quotient digit, subtraction, and bring-down written out in words.
6. 6Use Copy answer to grab the equation, Copy layout to copy the vertical work shown, or Copy full work for a complete plain-text report.

About this tool

Long Division Calculator works any whole-number division the way it is taught in classrooms: a vertical layout under the dividend, a quotient written across the top, and a step-by-step trace of every subtraction and bring-down. Type a dividend up to thirty digits and a non-zero divisor up to eighteen digits, then pick how you want the answer expressed. Quotient with remainder gives the classic schoolbook result (1234 divided by 7 is 176 R 2). Mixed number wraps the same answer into whole-number plus proper fraction form (176 and 2/7). Decimal expansion keeps dividing past the decimal point and detects repeating cycles using the standard remainder-position trick: the first remainder that appears twice marks the start of the repetend, and the repeated block is wrapped in parentheses (so 1 divided by 7 reads 0.(142857) and 1 divided by 3 reads 0.(3)). The tool flags terminating decimals (divisors whose only prime factors are 2 and 5), reports cycle lengths, and shows where the non-repeating prefix ends. Eight one-click presets cover the most-searched practice values (1234 by 7, 100000 by 23, 1 by 7, 22 by 7, 355 by 113, and more). Every step lists the partial dividend, the chosen quotient digit, the product subtracted, the running remainder, and the digit brought down next, so the work matches what a student would write in a notebook. The vertical layout is a monospace text block that you can copy straight into a worksheet, a chat message, or a notes app. All arithmetic is done with BigInt, so even 30-digit problems are exact at every position, and everything runs locally in your browser: the numbers you enter are never uploaded.
