Let's divide 877972 by 91
We want to divide 877972 by 91.

On to step 1:
When dividing 8 by 91, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 91

Moving on to step 2:
91 can be fit into 87 0 times, resulting in a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Take the next digit (7) from the dividend and append it to 87, then repeat: 877 / 91

Advancing to step 3:
877 divided by 91 is 9 with a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 819 from 877 and we're left with 58.
Grab the next digit (9) from the dividend, add it to 58, then carry on: 589 / 91

Moving on to step 4:
If we divide 589 by 91, we get 6 and a remainder of 43.
Use 6 as the next digit of our solution. 
Result so far: 96.0
If we take 546 away from 589, we end up with 43.
Bring next digit (7) of the dividend behind the 43 and repeat the process: 437 / 91

Let's proceed to step 5:
91 can be fit into 437 4 times, resulting in a remainder of 73.
Record the quotient 4 as the next digit in the result. 
Result so far: 964.0
Subtract 364 from 437 to get 73.
Fetch the next digit (2) from the dividend, attach it to 73 and continue: 732 / 91

Step 6:
When dividing 732 by 91, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 9648.0
The remainder is 4 after subtracting 728 from 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
91 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 9648.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
If we divide 400 by 91, we get 4 and a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 9648.04
Deduct 364 from 400 and we're left 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.

Going ahead to step 9:
If we divide 360 by 91, we get 3 and a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 9648.043
The remainder is 87 after subtracting 273 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 10:
91 can be fit into 870 9 times, resulting in a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 9648.0439
The remainder is 51 after subtracting 819 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 11:
When dividing 510 by 91, we get 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 9648.04395
The remainder is 55 after subtracting 455 from 510.
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 12:
91 can be fit into 550 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 9648.043956
Subtract 546 from 550 to 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.

Step 13:
91 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 9648.043956
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
91 goes into 400 4 times with a remainder of 36.
The next digit of our result is 4. 
Result so far: 9648.04395604
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.

In conclusion, the division gives 9648.04395604 with a balance of 3.6e-08.
