  1. Review:Long Division of Whole Numbers Example: 52212 Write the quotient as a mixed number.

  2. Divide: how many times does 12 go into 52 without going over?

  3. Divide: how many times does 12 go into 52 without going over?

  4. Divide: how many times does 12 go into 52 without going over? Multiply 412:

  5. Divide: how many times does 12 go into 52 without going over? Multiply 412:

  6. Divide: how many times does 12 go into 52 without going over? Multiply 412: Here we subtract:

  7. Divide: how many times does 12 go into 52 without going over? Multiply 412: Here we subtract:

  8. Divide: 12 into 44:

  9. Divide: 12 into 44:

  10. Divide: 12 into 44: Multiply:

  11. Divide: 12 into 44: Multiply: Subtract:

  12. Notice the repeated pattern of operations. Divide: Multiply: Subtract:

  13. As we have 8 pizzas, or whatever, leftover to divide among 12 people, each person gets an additional 8/12:

  14. As we have 8 pizzas, or whatever, leftover to divi de among 12 people, each person gets an additional 8/12:

  15. As we have 8 pizzas, or whatever, leftover to divi de among 12 people, each person gets an additional 8/12: Note that the fraction part is the remainder the divisor .

  16. Reducing:

  17. Badda-Bing, Baby! That’s all there is to it.

  18. Example 2: 653015

  19. Divide: 15 goes into 65…

  20. Divide: 15 goes into 65 4 times

  21. Divide: 15 goes into 65 4 times Multiply:

  22. Divide: 15 goes into 65 4 times Multiply: Subtract:

  23. Divide: 15 goes into 53 3 times

  24. Divide: 15 goes into 53 3 times Multiply:

  25. Divide: 15 goes into 53 3 times Multiply: Subtract:

  26. Divide: 15 goes into 80 5 times

  27. Divide: 15 goes into 80 5 times Multiply:

  28. Divide: 15 goes into 80 5 times Multiply: Subtract:

  29. We’re done when this difference, 5, is smaller than the divisor, 15.

  30. We’re done when this difference, 5, is smaller than the divisor, 15. So, closing the deal:
