Step-by-step solution

To solve the division of 7235 by 28, we will use the long division method:

  • Step 1: Determine how many times 28 can go into the first part of the number, 72. Since 28×2=56 28 \times 2 = 56 and 28×3=84 28 \times 3 = 84 , 28 fits into 72 twice. Write 2 on top.
  • Step 2: Subtract 56 56 from 72 72 to get 16 16 . Bring down the next digit, which is 3, making it 163.
  • Step 3: Determine how many times 28 fits into 163. Since 28×5=140 28 \times 5 = 140 and 28×6=168 28 \times 6 = 168 , 28 fits in 163 five times. Write 5 on top next to 2.
  • Step 4: Subtract 140 140 from 163 163 to get 23 23 . Bring down the final digit, 5, making it 235.
  • Step 5: Determine how many times 28 fits into 235. Since 28×8=224 28 \times 8 = 224 and 28×9=252 28 \times 9 = 252 , 28 fits into 235 eight times. Write 8 on top next to the 25, making our partial quotient 258.
  • Step 6: Subtract 224 224 from 235 235 to get a remainder of 11 11 .

Therefore, when dividing 7235 by 28, the quotient is 258 258 with a remainder of 11 11 .

The correct answer to the multiple-choice question is Option 2: \text{Option 2:} 258 258 with a remainder of 11 11 .
