(A) Perform long division: 999 ÷ 10. Step 1: 10 goes into 99 (first two digits) 9 times. 10 × 9 = 90 99 - 90 = 9 Bring down 9 to get 99. Step 2: 10 goes into 99 9 times. 10 × 9 = 90 99 - 90 = 9 Step 3: Place decimal in quotient. Add 0 to remainder: 90. 10 goes into 90 9 times. 10 × 9 = 90 90 - 90 = 0 Quotient is 99.9. 99.9 (B) Perform long division: 9801 ÷ 9. Step 1: 9 goes into 9 1 time. 9 × 1 = 9 9 - 9 = 0 Bring down 8 to get 8. Step 2: 9 goes into 8 0 times. 9 × 0 = 0 8 - 0 = 8 Bring down 0 to get 80. Step 3: 9 goes into 80 8 times. 9 × 8 = 72 80 - 72 = 8 Bring down 1 to get 81. Step 4: 9 goes into 81 9 times. 9 × 9 = 81 81 - 81 = 0 Quotient is 1089. 1089 (C) Perform long division: 99909 ÷ 9. Step 1: 9 goes into 9 1 time. 9 × 1 = 9 9 - 9 = 0 Bring down 9 to get 9. Step 2: 9 goes into 9 1 time. 9 × 1 = 9 9 - 9 = 0 Bring down 9 to get 9. Step 3: 9 goes into 9 1 time. 9 × 1 = 9 9 - 9 = 0 Bring down 0 to get 0. Step 4: 9 goes into 0 0 times. 9 × 0 = 0 0 - 0 = 0 Bring down 9 to get 9. Step 5: 9 goes into 9 1 time. 9 × 1 = 9 9 - 9 = 0 Quotient is 11101. 11101 (D) Perform long division: 999909 ÷ 9. Step 1: 9 goes into 9 1 time. 9 × 1 = 9 9 - 9 = 0 Bring down 9 to get 9. Step 2: 9 goes into 9 1 time. 9 × 1 = 9 9 - 9 = 0 Bring down 9 to get 9. Step 3: 9 goes into 9 1 time. 9 × 1 = 9 9 - 9 = 0 Bring down 9 to get 9. Step 4: 9 goes into 9 1 time. 9 × 1 = 9 9 - 9 = 0 Bring down 0 to get 0. Step 5: 9 goes into 0 0 times. 9 × 0 = 0 0 - 0 = 0 Bring down 9 to get 9. Step 6: 9 goes into 9 1 time. 9 × 1 = 9 9 - 9 = 0 Quotient is 111101. 111101
