Long Division Calculator with Steps
Calculate long division with steps, quotient, and remainder. Divide whole numbers exactly and check each subtraction in your browser.
Long division splits a whole-number dividend into equal groups determined by the divisor. This calculator shows each quotient digit, multiplication, subtraction, and remainder, using exact integer arithmetic.
You receive the quotient, remainder, digit-by-digit steps, and the identity divisor × quotient + remainder = dividend.

- Calculate whole-number groups and leftover quantities.
- Verify division of integers larger than the safe floating-point range.
Instructions
- Enter a nonnegative whole-number dividend.
- Enter a positive whole-number divisor.
- Select Calculate division and inspect the steps.
- Check the verification identity before using the result.
Example
Input: Dividend 1234; divisor 12
Settings: Whole-number division
Result: Quotient 102; remainder 10. Check: 12 × 102 + 10 = 1234.
A zero quotient digit matters: after subtracting 12 from 12, bring down 3, then 4.
Limits
- Each input accepts at most 200 decimal digits.
- Decimals, negative inputs, fractions, and polynomial division are not supported.
- Leading zero steps can appear when the partial dividend is smaller than the divisor.
