We're dividing 77640505 by 728 
We want to divide 77640505 by 728.

On to step 1:
7 divided by 728 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 728

Moving on to step 2:
728 goes into 77 0 times with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Include the next digit (6) from the dividend after 77, then repeat: 776 / 728

Going ahead to step 3:
776 divided by 728 is 1 with a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 728 from 776, we get 48.
Grab the next digit (4) from the dividend, add it to 48, then carry on: 484 / 728

Let's proceed to step 4:
The number 728 fits into 484 0 times, leaving a remainder of 484.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 484, we get 484.
Bring next digit (0) of the dividend behind the 484 and repeat the process: 4840 / 728

On to step 5:
If we divide 4840 by 728, we get 6 and a remainder of 472.
Use 6 as the next digit of our solution. 
Result so far: 106.0
The remainder is 472 after subtracting 4368 from 4840.
Include the next digit (5) from the dividend after 472, then repeat: 4725 / 728

Moving on to step 6:
If we divide 4725 by 728, we get 6 and a remainder of 357.
Put 6 as the next digit of the answer. 
Result so far: 1066.0
Deduct 4368 from 4725 and we're left with 357.
Grab the next digit (0) from the dividend, add it to 357, then carry on: 3570 / 728

Going ahead to step 7:
728 can be fit into 3570 4 times, resulting in a remainder of 658.
Record the quotient 4 as the next digit in the result. 
Result so far: 10664.0
The remainder is 658 after subtracting 2912 from 3570.
Grab the next digit (5) from the dividend, add it to 658, then carry on: 6585 / 728

Let's proceed to step 8:
728 can be fit into 6585 9 times, resulting in a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 106649.0
If we take 6552 away from 6585, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
When dividing 330 by 728, we get 0 with a remainder of 330.
The number 0 becomes the next digit in our result. 
Result so far: 106649.0
Subtract 0 from 330 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 10:
When dividing 3300 by 728, we get 4 with a remainder of 388.
Write down 4 as next digit of the result. 
Result so far: 106649.04
The remainder is 388 after subtracting 2912 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 11:
3880 divided by 728 is 5 with a remainder of 240.
Write down 5 as next digit of the result. 
Result so far: 106649.045
Subtracting 3640 from 3880 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 12:
2400 divided by 728 is 3 with a remainder of 216.
Write down 3 as next digit of the result. 
Result so far: 106649.0453
The remainder is 216 after subtracting 2184 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 13:
728 can be fit into 2160 2 times, resulting in a remainder of 704.
The number 2 becomes the next digit in our result. 
Result so far: 106649.04532
The remainder is 704 after subtracting 1456 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Going ahead to step 14:
7040 divided by 728 is 9 with a remainder of 488.
The number 9 becomes the next digit in our result. 
Result so far: 106649.045329
Subtracting 6552 from 7040 leaves us with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Advancing to step 15:
When dividing 4880 by 728, we get 6 with a remainder of 512.
Write down 6 as next digit of the result. 
Result so far: 106649.0453296
If we subtract 4368 from 4880, we get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Moving on to step 16:
When dividing 5120 by 728, we get 7 with a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 106649.04532967
Deduct 5096 from 5120 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 106649.04532967 with a balance of 2.4e-08.
