We're dividing 728817 by 52 
We want to figure out the number of times 728817 can be divided by 52.

On to step 1:
52 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 52

Advancing to step 2:
72 divided by 52 is 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 52 from 72 and we're left with 20.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 52

On to step 3:
208 divided by 52 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 208 from 208 and we're left with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 52

Moving on to step 4:
When dividing 8 by 52, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 140.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 52

Going ahead to step 5:
The number 52 fits into 81 1 times, leaving a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1401.0
Subtract 52 from 81 to get 29.
Fetch the next digit (7) from the dividend, attach it to 29 and continue: 297 / 52

Moving on to step 6:
297 divided by 52 is 5 with a remainder of 37.
The number 5 becomes the next digit in our result. 
Result so far: 14015.0
If we subtract 260 from 297, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
If we divide 370 by 52, we get 7 and a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 14015.7
If we take 364 away from 370, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
The number 52 fits into 60 1 times, leaving a remainder of 8.
The next digit of our result is 1. 
Result so far: 14015.71
If we subtract 52 from 60, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
When dividing 80 by 52, we get 1 with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 14015.711
Deduct 52 from 80 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 14015.711 with a remainder of 0.0028.
