Dividing 3 and 4 Digits
by 2 Digits

2. 800 ÷ 20 = 40
80,000 ÷ 200 =
400
8,000 ÷ 20 =
400
80,000 ÷ 2,000 = 40
80,000 ÷ 20 =
4,000
800,000 ÷ 2,000 =
400 40
8,000,000 ÷ 200 =

8,000 ÷ 200 =

3. How to Divide
2 Digits into
3 Digits

4. Round 948 to nearest hundred
First: Estimate
9 4 8 ÷ 21
Round 948 to nearest hundred
Round 21 to nearest ten
900 ÷ 20 = 45
Answer should be about 45

5. 2 1) 9 4 8 4 Step 1: Divide Divide 21 into 1st number in the dividend
21 will not go into 9 so you look at 94.
How many 20’s will go into 90?
Use mental math to round 21 and 94.
About 4
Put your answer above the 4.

6. Step 2: Multiply 4
Multiply the divisor times the first number in your quotient.
2 1) 9 4 8 8 4
Write your answer directly under the 94 or the number you just divided into.
4 x 21=84

7. 4 2 1) 9 4 8 8 4 1 Step 3: Subtract Draw a line under the 84.
Write a subtraction sign next to the 84. 8 4 1
Subtract 84 from 94.
Write your answer directly below the 84.

8. Step 4: Bring Down 4
Go to the next number in the dividend to the right of the 4
2 1) 9 4 8 8 4
Write an arrow under that number. 1 8
Bring the 8 down

9. Step 5: Repeat 4
Decide if you repeat the 5 steps of division.
2 1) 9 4 8 8 4 1 8
If your divisor (21) can divide into your new number (108), or if you have numbers that have not been brought down, you repeat the 5 steps of division.

10. 4 5 2 1) 9 4 8 8 4 1 8 Divide Divide 21 into your new number, 108.
Use mental math to round 21 and 108. 1 8
Divide 20 into 110
Place your answer directly above the 8 in your quotient.

11. 2. Multiply 4 5
Multiply your divisor, 21, with your new number in the quotient, 5.
2 1) 9 4 8 8 4
Place your answer directly under the 108. 1 8 1 5

12. 3. Subtract 4 5
Draw a line under the bottom number, 105.
2 1) 9 4 8 8 4
Draw a subtraction sign. 1 8 1 5
Subtract & place answer under the line. 3

13. 4. Bring down 4 5
2 1) 9 4 8
Since there is nothing to bring down, go to step five. 8 4 1 8 1 5 3

14. 5. Repeat or Remainder
If the 21 will not divide into your new number, 3, & there is nothing to bring down, you are done. 4 5
2 1) 9 4 8 8 4
What do we do with the remainder of 3? 1 8 1 5 3

15. 4 5 2 1) 9 4 8 8 4 1 8 1 5 3 Remainder __ 3 1 __ = 21 7 Divisor
Write your remainder in the form of a fractions and simplify 1 8 1 5 3
