Long Division Calculator
Work through a long division problem and show the quotient and remainder.
Divide two integers
Enter a dividend and a non-zero divisor. The calculator reports the quotient and remainder so you can check the division relationship. For a hand-written assignment, use the displayed relationship as a check and write the long-division layout required by the class.
Division relationship
Dividend equals divisor multiplied by quotient plus remainder. The remainder must be smaller than the absolute divisor. A decimal quotient may continue beyond the integer remainder when the problem asks for a decimal answer.
Worked example
125 divided by 8 gives a quotient of 15 and a remainder of 5 because 8 × 15 + 5 = 125.
