We look at the division of 75789991 by 728 
Let's see how many times 728 fits into 75789991.

Let's proceed to step 1:
728 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 728

On to step 2:
When dividing 75 by 728, we get 0 with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Bring next digit (7) of the dividend behind the 75 and repeat the process: 757 / 728

Going ahead to step 3:
If we divide 757 by 728, we get 1 and a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 728 from 757 to get 29.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 728

Going ahead to step 4:
298 divided by 728 is 0 with a remainder of 298.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 298, we get 298.
Fetch the next digit (9) from the dividend, attach it to 298 and continue: 2989 / 728

On to step 5:
The number 728 fits into 2989 4 times, leaving a remainder of 77.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
If we take 2912 away from 2989, we end up with 77.
Grab the next digit (9) from the dividend, add it to 77, then carry on: 779 / 728

Let's proceed to step 6:
779 divided by 728 is 1 with a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 1041.0
Subtracting 728 from 779 leaves us with 51.
Include the next digit (9) from the dividend after 51, then repeat: 519 / 728

On to step 7:
519 divided by 728 is 0 with a remainder of 519.
Record the quotient 0 as the next digit in the result. 
Result so far: 10410.0
Deduct 0 from 519 and we're left with 519.
Include the next digit (1) from the dividend after 519, then repeat: 5191 / 728

On to step 8:
728 goes into 5191 7 times with a remainder of 95.
Use 7 as the next digit of our solution. 
Result so far: 104107.0
Deduct 5096 from 5191 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 9:
If we divide 950 by 728, we get 1 and a remainder of 222.
Use 1 as the next digit of our solution. 
Result so far: 104107.1
If we take 728 away from 950, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Moving on to step 10:
When dividing 2220 by 728, we get 3 with a remainder of 36.
The next digit of our result is 3. 
Result so far: 104107.13
Deduct 2184 from 2220 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
If we divide 360 by 728, we get 0 and a remainder of 360.
Put 0 as the next digit of the answer. 
Result so far: 104107.13
If we subtract 0 from 360, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 12:
When dividing 3600 by 728, we get 4 with a remainder of 688.
Use 4 as the next digit of our solution. 
Result so far: 104107.1304
If we subtract 2912 from 3600, we get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Going ahead to step 13:
728 goes into 6880 9 times with a remainder of 328.
Write down 9 as next digit of the result. 
Result so far: 104107.13049
The remainder is 328 after subtracting 6552 from 6880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 14:
When dividing 3280 by 728, we get 4 with a remainder of 368.
The number 4 becomes the next digit in our result. 
Result so far: 104107.130494
Subtract 2912 from 3280 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 15:
728 can be fit into 3680 5 times, resulting in a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 104107.1304945
If we take 3640 away from 3680, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 16:
728 goes into 400 0 times with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 104107.1304945
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 104107.1304945 with a remainder of 4e-07.
