84 : 9 = 9 rest 3

9 × 9 + 3 = 81 + 3 = 84

28 : 3 = 9 rest 1

9 × 3 + 1 = 27 + 1 = 28

49 : 7 = 7

7 × 7 = 49

10 : 5 = 2

2 × 5 = 10

63 : 8 = 7 rest 7

7 × 8 + 7 = 56 + 7 = 63

37 : 6 = 6 rest 1

6 × 6 + 1 = 36 + 1 = 37

50 : 9 = 5 rest 5

5 × 9 + 5 = 45 + 5 = 50

29 : 4 = 7 rest 1

7 × 4 + 1 = 28 + 1 = 29
