We look at the division of 71912459 by 728 
Let's see how many times 728 fits into 71912459.

Step 1:
728 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
If we subtract 0 from 7, we get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 728

Step 2:
728 goes into 71 0 times with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Grab the next digit (9) from the dividend, add it to 71, then carry on: 719 / 728

Advancing to step 3:
When dividing 719 by 728, we get 0 with a remainder of 719.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 719, we get 719.
Bring next digit (1) of the dividend behind the 719 and repeat the process: 7191 / 728

Moving on to step 4:
728 goes into 7191 9 times with a remainder of 639.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 6552 from 7191 and we're left with 639.
Bring next digit (2) of the dividend behind the 639 and repeat the process: 6392 / 728

On to step 5:
When dividing 6392 by 728, we get 8 with a remainder of 568.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
Deduct 5824 from 6392 and we're left with 568.
Include the next digit (4) from the dividend after 568, then repeat: 5684 / 728

Advancing to step 6:
The number 728 fits into 5684 7 times, leaving a remainder of 588.
Record the quotient 7 as the next digit in the result. 
Result so far: 987.0
The remainder is 588 after subtracting 5096 from 5684.
Append the next digit (5) from the dividend to 588 and continue with: 5885 / 728

Step 7:
If we divide 5885 by 728, we get 8 and a remainder of 61.
The next digit of our result is 8. 
Result so far: 9878.0
Subtract 5824 from 5885 to get 61.
Grab the next digit (9) from the dividend, add it to 61, then carry on: 619 / 728

Let's proceed to step 8:
728 can be fit into 619 0 times, resulting in a remainder of 619.
Record the quotient 0 as the next digit in the result. 
Result so far: 98780.0
If we take 0 away from 619, we end up with 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

On to step 9:
6190 divided by 728 is 8 with a remainder of 366.
The number 8 becomes the next digit in our result. 
Result so far: 98780.8
Deduct 5824 from 6190 and we're left with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Let's proceed to step 10:
3660 divided by 728 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 98780.85
If we take 3640 away from 3660, we end up 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.

Advancing to step 11:
728 goes into 200 0 times with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 98780.85
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 12:
2000 divided by 728 is 2 with a remainder of 544.
Use 2 as the next digit of our solution. 
Result so far: 98780.8502
Subtract 1456 from 2000 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Advancing to step 13:
5440 divided by 728 is 7 with a remainder of 344.
The number 7 becomes the next digit in our result. 
Result so far: 98780.85027
Subtract 5096 from 5440 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

On to step 14:
When dividing 3440 by 728, we get 4 with a remainder of 528.
Write down 4 as next digit of the result. 
Result so far: 98780.850274
If we subtract 2912 from 3440, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Step 15:
The number 728 fits into 5280 7 times, leaving a remainder of 184.
Record the quotient 7 as the next digit in the result. 
Result so far: 98780.8502747
Deduct 5096 from 5280 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 16:
If we divide 1840 by 728, we get 2 and a remainder of 384.
The number 2 becomes the next digit in our result. 
Result so far: 98780.85027472
Subtract 1456 from 1840 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

The final result is 98780.85027472 with a remainder of 3.84e-07.
