Long Division Calculator
That Shows and Explains Each Step
[ Skip to Calculator ]
The Long Division Calculator on this page will show and explain the steps it took to solve the division problem.
This free online calculator will divide one number (dividend) by another number (divisor) using the long division method, and show and explain each step.
The calculator will accommodate divisors and dividends containing decimal points, and will give the remainder in both the whole number and the decimal format.
Plus, unlike other online long division calculators, the calculated results will list the 19 multiples of the divisor to help you learn your factors, and will also report the detection of patterns which may indicate the result is a recurring decimal.
How To Do Long Division
To show you how to do long division I will give the actual calculator results involving four common long division scenarios:
 Dividing whole numbers with no remainder.
 Dividing whole numbers with whole remainder.
 Dividing decimal numbers with no remainder.
 Dividing decimal numbers with decimal remainder.
To follow the steps I took as I proceeded through each long division example, scroll each questionmark to the top portion of screen and hover your mouse over the question mark.

Since 3.33 x 30.027027027 does not equal 99.99, either the calculator ran out of room before the long division was completed, the quotient contains a recurring decimal, or there is a rounding issue between the calculated result and the long division result. In this case it appears to be a repeating decimal.

With that, let's use the Long Division Calculator to create a stepbystep explanation of how to use long division to find the quotient of one number divided by another, and to check your work during long division practice sessions.
