How it works
Long division repeats four small steps until the digits run out. This long division graphic organizer gives each step a row, so a student who loses the thread can see which step comes next.

One column for each digit of the answer
Each time round the four steps gives one digit of the quotient. A three-digit number divided by a one-digit number takes three rounds at most, so the opening chart has three columns. When the first digit is too small to divide, start with the first two digits and leave the last column empty.
Check after every subtraction
What is left after a subtraction has to be smaller than the divisor. If it is not, the digit just written in the quotient is too small.
- A zero in the quotient is still a round: write the 0, then bring down the next digit.
- On lined paper, turn the page sideways. The lines become columns that keep the digits in their places.
Questions and answers
What are the steps of long division?
Divide, multiply, subtract and bring down. Divide the first digits of the dividend by the divisor, multiply the answer by the divisor, subtract, then bring down the next digit. Repeat until no digits are left.
How do you check a long division answer?
Multiply the quotient by the divisor, then add the remainder. The result should equal the dividend. For 857 ÷ 6 = 142 remainder 5, the check is 142 × 6 = 852, and 852 + 5 = 857.
What is the difference between a dividend and a divisor?
The dividend is the number being divided, and the divisor is the number it is divided by. The result is the quotient. In 857 ÷ 6, the dividend is 857 and the divisor is 6.
What grade do students learn long division?
In the Common Core standards, 4th graders divide numbers of up to four digits by one-digit numbers and 5th graders by two-digit numbers, using place value strategies. Dividing multi-digit numbers fluently with the standard algorithm is a 6th grade standard.
