We're dividing 728942 by 75 
Our goal is to divide 728942 by 75.

On to step 1:
75 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 75

Advancing to step 2:
If we divide 72 by 75, we get 0 and a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Take the next digit (8) from the dividend and append it to 72, then repeat: 728 / 75

On to step 3:
The number 75 fits into 728 9 times, leaving a remainder of 53.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 675 from 728, we get 53.
Include the next digit (9) from the dividend after 53, then repeat: 539 / 75

Going ahead to step 4:
If we divide 539 by 75, we get 7 and a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 97.0
Deduct 525 from 539 and we're left with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 75

Step 5:
The number 75 fits into 144 1 times, leaving a remainder of 69.
Use 1 as the next digit of our solution. 
Result so far: 971.0
Subtracting 75 from 144 leaves us with 69.
Fetch the next digit (2) from the dividend, attach it to 69 and continue: 692 / 75

Going ahead to step 6:
692 divided by 75 is 9 with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 9719.0
Subtract 675 from 692 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
75 goes into 170 2 times with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 9719.2
Deduct 150 from 170 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
The number 75 fits into 200 2 times, leaving a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 9719.22
Subtracting 150 from 200 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 9719.22, and the remainder is 0.05.
