  1. Division Algorithms By: Jessica Nastasi

  2. Tail Division!3 digit by 1 digit

  3. 5 456 Step 1: Set up the problem

  4. 5 456 Step 2: Multiply the divisor by a number that will get you close to the dividend. Write this on the OUTSIDE. 80

  5. 5 456 Step 3: Subtract the product from the dividend. 80 -400 56

  6. 5 456 Step 4: Repeat with new amount! Keep going until the divisor is greater than the dividend. 80 -400 56 10 1 - 50 6 -5 1

  7. 5 456 91 R 1 Step 5: Add together the numbers on the side. This is your quotient! Whatever is left on the inside is your remainder. 80 -400 56 10 + 1 - 50 6 91 -5 1

  8. Step 6: Check with multiplication!! This makes sure your answer is correct!

  9. Tail Division!3 digit by 2 digit!

  10. Step 1: Set up the problem 22 546

  11. Step 2: Multiply the divisor by a number that will get you close to the dividend. Write this on the OUTSIDE. 22 546 10 -220 326

  12. Step 3: Multiply the divisor by a number that will get you close to the dividend. Write this on the OUTSIDE. 22 546 10 -220 326 10 -220 126

  13. Step 4: Multiply the divisor by a number that will get you close to the dividend. Write this on the OUTSIDE. 22 546 10 -220 326 10 5 -220 126 -110 16

  14. Step 5: Add to find your answer! 24R 18 22 546 10 -220 326 10 4 -220 106 + 24 - 88 18

  15. Step 6: Check with multiplication!! This makes sure your answer is correct!

  16. Long Division! 2 digit by 1 digit

  17. Remember: Did Mom Serve Brownies Saturday?

  18. Step 1: Set up the problem 5 96

  19. Step 2: Dividethe ones: “Did” 1 5 96

  20. Step 3: Multiply: “Mom” 1 5 96 5

  21. Step 4: Subtract: “Serve” 1 5 96 5 - 4

  22. Step 5: Bring Down: “Brownies” 1 5 96 -5 4 6

  23. Step 6: Start Again with the New Number! “Saturday” Divide, Multiply, Subtract! 1 9 R 1 5 96 -5 46 -45 1

  24. Last: Check with multiplication!! This makes sure your answer is correct!

  25. Long Division! 3 digit by 1 digit

  26. Step 1: Set up the problem 7 895

  27. Step 2: Divide:“Does” 1 7 895

  28. Step 3: Multiply:“Mom” 1 7 895 7

  29. Step 4: Subtract:“Serve” 1 7 895 7 - 1

  30. Step 5: Bring Down:“Brownies” 1 7 895 -7 1 9

  31. Step 6: Start Again with the New Number!“Saturday” Divide, Multiply, Subtract, Bring Down 1 2 7 895 -7 1 9 -14 5 5

  32. Step 7: Start Again with the New Number!“Saturday” Divide, Multiply, Subtract 7 1 2 R 6 7 895 -7 1 9 -14 5 5 -49 6

  33. Last: Check with multiplication!! This makes sure your answer is correct!

  34. Long Division! Zeros in the Quotient 3 digit by 1 digit

  35. Step 1: Set up the problem 5 496

  36. Step 2: Divide the ones: “Did” • If it is not divisible, move over! 0 5 496

  37. Step 3: Multiply: “Mom” 0 9 5 496 45

  38. Step 4: Subtract “Serve” 0 9 5 496 45 - 4

  39. Step 5: Bring Down “Brownies” 9 0 5 496 -45 4 6

  40. Step 6: Start Again! “Saturday” R1 9 9 0 5 496 -45 4 6 -45 1

  41. Last: Check with multiplication!! This makes sure your answer is correct!
