We're dividing 87151710 by 728 
We're looking to find how many times 728 goes into 87151710.

On to step 1:
8 divided by 728 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 728

Let's proceed to step 2:
If we divide 87 by 728, we get 0 and a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Take the next digit (1) from the dividend and append it to 87, then repeat: 871 / 728

On to step 3:
When dividing 871 by 728, we get 1 with a remainder of 143.
The next digit of our result is 1. 
Result so far: 1.0
If we take 728 away from 871, we end up with 143.
Grab the next digit (5) from the dividend, add it to 143, then carry on: 1435 / 728

Step 4:
1435 divided by 728 is 1 with a remainder of 707.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 728 from 1435 to get 707.
Take the next digit (1) from the dividend and append it to 707, then repeat: 7071 / 728

Let's proceed to step 5:
If we divide 7071 by 728, we get 9 and a remainder of 519.
Use 9 as the next digit of our solution. 
Result so far: 119.0
Subtracting 6552 from 7071 leaves us with 519.
Grab the next digit (7) from the dividend, add it to 519, then carry on: 5197 / 728

Advancing to step 6:
If we divide 5197 by 728, we get 7 and a remainder of 101.
Use 7 as the next digit of our solution. 
Result so far: 1197.0
Subtracting 5096 from 5197 leaves us with 101.
Bring next digit (1) of the dividend behind the 101 and repeat the process: 1011 / 728

Going ahead to step 7:
The number 728 fits into 1011 1 times, leaving a remainder of 283.
Write down 1 as next digit of the result. 
Result so far: 11971.0
Subtracting 728 from 1011 leaves us with 283.
Bring next digit (0) of the dividend behind the 283 and repeat the process: 2830 / 728

Going ahead to step 8:
The number 728 fits into 2830 3 times, leaving a remainder of 646.
Put 3 as the next digit of the answer. 
Result so far: 119713.0
Subtract 2184 from 2830 to get 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Moving on to step 9:
6460 divided by 728 is 8 with a remainder of 636.
Record the quotient 8 as the next digit in the result. 
Result so far: 119713.8
Subtract 5824 from 6460 to get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Advancing to step 10:
When dividing 6360 by 728, we get 8 with a remainder of 536.
Put 8 as the next digit of the answer. 
Result so far: 119713.88
The remainder is 536 after subtracting 5824 from 6360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

The final result is 119713.88 with a remainder of 0.536.
