12799427 ÷ 91 
Our goal is to divide 12799427 by 91.

Moving on to step 1:
91 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 91

On to step 2:
91 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 91

Let's proceed to step 3:
127 divided by 91 is 1 with a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 36 after subtracting 91 from 127.
Append the next digit (9) from the dividend to 36 and continue with: 369 / 91

Going ahead to step 4:
369 divided by 91 is 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 364 from 369, we get 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 91

On to step 5:
If we divide 59 by 91, we get 0 and a remainder of 59.
Write down 0 as next digit of the result. 
Result so far: 140.0
The remainder is 59 after subtracting 0 from 59.
Grab the next digit (4) from the dividend, add it to 59, then carry on: 594 / 91

Going ahead to step 6:
594 divided by 91 is 6 with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 1406.0
If we subtract 546 from 594, we get 48.
Fetch the next digit (2) from the dividend, attach it to 48 and continue: 482 / 91

On to step 7:
When dividing 482 by 91, we get 5 with a remainder of 27.
The number 5 becomes the next digit in our result. 
Result so far: 14065.0
The remainder is 27 after subtracting 455 from 482.
Fetch the next digit (7) from the dividend, attach it to 27 and continue: 277 / 91

Step 8:
If we divide 277 by 91, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 140653.0
Deduct 273 from 277 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
40 divided by 91 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 140653.0
If we take 0 away from 40, 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.

Advancing to step 10:
400 divided by 91 is 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 140653.04
Subtracting 364 from 400 leaves us 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.

Advancing to step 11:
The number 91 fits into 360 3 times, leaving a remainder of 87.
Record the quotient 3 as the next digit in the result. 
Result so far: 140653.043
Subtract 273 from 360 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 12:
When dividing 870 by 91, we get 9 with a remainder of 51.
The next digit of our result is 9. 
Result so far: 140653.0439
Subtracting 819 from 870 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 13:
When dividing 510 by 91, we get 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 140653.04395
If we take 455 away from 510, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 14:
91 can be fit into 550 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 140653.043956
If we subtract 546 from 550, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 15:
When dividing 40 by 91, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 140653.043956
Deduct 0 from 40 and we're left 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.

Step 16:
91 can be fit into 400 4 times, resulting in a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 140653.04395604
The remainder is 36 after subtracting 364 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 140653.04395604, with a leftover of 3.6e-08.
