Long Division Calculator
Divide an entered integer dividend by a positive divisor. Each digit reports the partial dividend, quotient digit, product, subtraction, and remainder before the final identity check.
How to use the Long Division Calculator
Enter a nonnegative integer dividend and a positive integer divisor.
Review sign convention, decimal precision, repeating-decimal truncation, and whether an integer remainder or decimal quotient is required.
Read whole-number quotient, remainder, decimal quotient, long-division steps, and identity check.
Formula
For nonnegative integer dividend a and positive integer divisor b, a = bq + r, where q = floor(a ÷ b) and 0 ≤ r < b.
Example
1,257 ÷ 12 gives quotient 104 and remainder 9 because 12 × 104 + 9 = 1,257.
Assumptions and limitations
- The dividend is nonnegative, the divisor is positive, and the displayed decimal quotient is rounded by the interface.
- Long Division Calculator treats the entered values as estimates and does not infer missing project, account, or personal details.
- Calculations retain working precision except where the cited method requires an intermediate rounding step; displayed values are then formatted separately. Source rules and dated rates must be rechecked when they change.
