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 = 40,000 8,000 ÷ 200 =

How to Divide 2 Digits into 3 Digits

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

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.

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

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.

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

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.

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.

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

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

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

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

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
