Long division answer
156 ÷ 12
13
156 = 12 × 13 + 0
Set up the problem: Both values are whole numbers, so no decimal shift is needed.
Step-by-step long division
- Step 112 × 0 = 0
Bring down 1 to make 1. 12 goes into 1 0 times. Write 0, multiply 12 × 0 = 0, then subtract to get 1.

Long Division Calculator FAQ
What is a long division calculator?
A long division calculator divides one number by another and shows how each quotient digit is found through repeated division, multiplication, subtraction, and bring-down steps.
How do you divide decimals with long division?
Move the decimal point in both numbers the same number of places until the divisor is a whole number. Then divide the equivalent whole-number problem.
What does a remainder mean?
A remainder is the amount left after the divisor has been multiplied by the whole-number quotient and subtracted from the dividend.
Can a long division answer repeat forever?
Yes. Some fractions produce repeating decimals. This calculator shows the requested number of decimal places and marks an unfinished decimal with an ellipsis.
How can I check a long division answer?
Multiply the divisor by the whole-number quotient, then add the remainder. The result should equal the original dividend.
