Long division is explained in 5 steps: 1) Determine how many times the divisor goes into the first digit of the dividend and place that number above the digit. 2) Multiply the divisor by that number and place it under the digit. 3) Subtract and bring down the next digit. 4) Repeat steps 1-3 until there are no more digits to bring down. 5) The final number is the quotient of the long division problem. As an example, the document walks through 45/3 in detail using these steps, with the solution being 45/3=15.

2. Let’s being
45/3
• Dividend: the number that is being divided into
• Divisor: the number that is dividing into the dividend

3. Divide!
• To being, the dividend is placed inside of the dividing
symbol, and the divisor is placed on the left of the symbol
• Now we can begin!
3 45

4. Apply!
Step 1: figure out how many times 3 can go into
the first number of the dividend (4, in 45), and
place that number ABOVE the 4 outside of the
symbol.
1
3 can go into 4
Only 1 time. 3 45

5. Apply!
Step 2: Multiply 1 by the divisor (3), and place the outcome
UNDER the 4.
1x3=3
1
3 45
3

6. Apply!
Step 3: Subtract 3 from 4.
1
4-3=1 *because there is no
number subtracted
from 5, simply bring
it down next to 1.

- 3
15

7. Apply!
Step 4: Figure out how many times 3 can go into 15, and
place that number above 5 outside of the symbol
Hint: counting in
3’s until you get
to 15 will give you
your answer!
3..6..9..12..15!
1 2 3 4 5
15
3 45
- 3
15

8. Apply!
Step 5: Multiply 5 by the divisor (3), then place the amount
under 15 to subtract!
5x3=15
15-15=0
