91097620 ÷ 728 
We want to figure out the number of times 91097620 can be divided by 728.

On to step 1:
If we divide 9 by 728, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 728

Step 2:
728 goes into 91 0 times with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Take the next digit (0) from the dividend and append it to 91, then repeat: 910 / 728

Advancing to step 3:
When dividing 910 by 728, we get 1 with a remainder of 182.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 728 from 910 to get 182.
Include the next digit (9) from the dividend after 182, then repeat: 1829 / 728

On to step 4:
If we divide 1829 by 728, we get 2 and a remainder of 373.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 1456 from 1829, we get 373.
Take the next digit (7) from the dividend and append it to 373, then repeat: 3737 / 728

Let's proceed to step 5:
3737 divided by 728 is 5 with a remainder of 97.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
If we subtract 3640 from 3737, we get 97.
Include the next digit (6) from the dividend after 97, then repeat: 976 / 728

On to step 6:
728 can be fit into 976 1 times, resulting in a remainder of 248.
Put 1 as the next digit of the answer. 
Result so far: 1251.0
If we take 728 away from 976, we end up with 248.
Grab the next digit (2) from the dividend, add it to 248, then carry on: 2482 / 728

On to step 7:
728 can be fit into 2482 3 times, resulting in a remainder of 298.
Use 3 as the next digit of our solution. 
Result so far: 12513.0
If we take 2184 away from 2482, we end up with 298.
Grab the next digit (0) from the dividend, add it to 298, then carry on: 2980 / 728

Moving on to step 8:
2980 divided by 728 is 4 with a remainder of 68.
The next digit of our result is 4. 
Result so far: 125134.0
Subtract 2912 from 2980 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 9:
When dividing 680 by 728, we get 0 with a remainder of 680.
Put 0 as the next digit of the answer. 
Result so far: 125134.0
Subtract 0 from 680 to get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Advancing to step 10:
When dividing 6800 by 728, we get 9 with a remainder of 248.
Put 9 as the next digit of the answer. 
Result so far: 125134.09
The remainder is 248 after subtracting 6552 from 6800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 11:
When dividing 2480 by 728, we get 3 with a remainder of 296.
Record the quotient 3 as the next digit in the result. 
Result so far: 125134.093
Deduct 2184 from 2480 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 12:
The number 728 fits into 2960 4 times, leaving a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 125134.0934
If we subtract 2912 from 2960, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
728 can be fit into 480 0 times, resulting in a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 125134.0934
Subtract 0 from 480 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 14:
728 goes into 4800 6 times with a remainder of 432.
The next digit of our result is 6. 
Result so far: 125134.093406
The remainder is 432 after subtracting 4368 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Step 15:
728 can be fit into 4320 5 times, resulting in a remainder of 680.
The number 5 becomes the next digit in our result. 
Result so far: 125134.0934065
Subtract 3640 from 4320 to get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Advancing to step 16:
728 goes into 6800 9 times with a remainder of 248.
Write down 9 as next digit of the result. 
Result so far: 125134.09340659
Deduct 6552 from 6800 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

In conclusion, the division gives 125134.09340659 with a balance of 2.48e-07.
