3. Copyright © Ed2Net Learning, Inc.3 Repeated Subtraction Repeated Subtraction can also be used to find the Quotient. It states to take away over and over again.

4. Copyright © Ed2Net Learning, Inc.4 Steps to find Division using Repeated subtraction. Subtract the divisor from dividend again and again until you reach 0. Count the number of times you subtract the divisor. The quotient is the number of times you subtracted to reach 0.

5. Copyright © Ed2Net Learning, Inc.5 Example 12 ÷ 3 = Use repeated subtraction. Subtract 3 until you get 0. 12 – 3 = 9 9 – 3 = 6 6 – 3 = 3 3 – 3 = 0 Thus, 12 ÷ 3 = 4

6. Copyright © Ed2Net Learning, Inc.6 Patterns Patterns help to make the division of long numbers easy by making use of Basic Facts.

7. Copyright © Ed2Net Learning, Inc.7 Importance of basic fact The Quotient of the greater number is multiple of 10, 100 or 1,000 as that of the basic fact.

8. Copyright © Ed2Net Learning, Inc.8 Example If 16 ÷ 8 = 2 is the basic fact then Quotient of 1,600 ÷ 8 is the multiple of 100 of 2 Thus, Quotient of 1,600 ÷ 8 = 200 Quotient of 160 ÷ 8 = 20

9. Copyright © Ed2Net Learning, Inc.9 Use the basic facts and Patterns to find each Quotient 32 ÷ 4 = 320 ÷ 4 = 3,200 ÷ 4 = Answer- 8, 80, 800

10. Copyright © Ed2Net Learning, Inc.10 Divide a) 3,600 ÷ 6 = b) 180 ÷ 9 = Answer – a) 600 b) 20

11. Copyright © Ed2Net Learning, Inc.11 Dividing Using Number line To divide 10 ÷ 2, Use a number Line Start at 10. Jump Back by 2s until you reach 0. 0 1 2 3 4 5 6 7 8 9 10
