Let's divide 12799025 by 91
We want to figure out the number of times 12799025 can be divided by 91.

Let's proceed to step 1:
If we divide 1 by 91, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 91

Let's proceed to step 2:
91 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 91

Advancing to step 3:
91 goes into 127 1 times with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 91 from 127 and we're left with 36.
Include the next digit (9) from the dividend after 36, then repeat: 369 / 91

Advancing to step 4:
91 can be fit into 369 4 times, resulting in a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 364 from 369 leaves us with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 91

Let's proceed to step 5:
The number 91 fits into 59 0 times, leaving a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 140.0
Subtracting 0 from 59 leaves us with 59.
Take the next digit (0) from the dividend and append it to 59, then repeat: 590 / 91

Advancing to step 6:
91 can be fit into 590 6 times, resulting in a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 1406.0
Subtracting 546 from 590 leaves us with 44.
Include the next digit (2) from the dividend after 44, then repeat: 442 / 91

Moving on to step 7:
When dividing 442 by 91, we get 4 with a remainder of 78.
Write down 4 as next digit of the result. 
Result so far: 14064.0
The remainder is 78 after subtracting 364 from 442.
Take the next digit (5) from the dividend and append it to 78, then repeat: 785 / 91

Going ahead to step 8:
91 goes into 785 8 times with a remainder of 57.
The number 8 becomes the next digit in our result. 
Result so far: 140648.0
If we subtract 728 from 785, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 9:
The number 91 fits into 570 6 times, leaving a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 140648.6
If we subtract 546 from 570, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
The number 91 fits into 240 2 times, leaving a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 140648.62
If we subtract 182 from 240, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 11:
91 can be fit into 580 6 times, resulting in a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 140648.626
If we take 546 away from 580, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 12:
91 goes into 340 3 times with a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 140648.6263
Subtracting 273 from 340 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 13:
The number 91 fits into 670 7 times, leaving a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 140648.62637
Deduct 637 from 670 and we're left 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 14:
91 can be fit into 330 3 times, resulting in a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 140648.626373
If we subtract 273 from 330, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 15:
If we divide 570 by 91, we get 6 and a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 140648.6263736
If we take 546 away from 570, we end up 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.

Going ahead to step 16:
91 goes into 240 2 times with a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 140648.62637362
Subtract 182 from 240 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

In conclusion, the division gives 140648.62637362 with a balance of 5.8e-08.
