We look at the division of 866275 by 91 
Our goal is to divide 866275 by 91.

On to step 1:
If we divide 8 by 91, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 91

Step 2:
The number 91 fits into 86 0 times, leaving a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Bring next digit (6) of the dividend behind the 86 and repeat the process: 866 / 91

Going ahead to step 3:
91 goes into 866 9 times with a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 819 from 866, we get 47.
Include the next digit (2) from the dividend after 47, then repeat: 472 / 91

Advancing to step 4:
When dividing 472 by 91, we get 5 with a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 95.0
Deduct 455 from 472 and we're left with 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 91

Let's proceed to step 5:
91 can be fit into 177 1 times, resulting in a remainder of 86.
Record the quotient 1 as the next digit in the result. 
Result so far: 951.0
The remainder is 86 after subtracting 91 from 177.
Grab the next digit (5) from the dividend, add it to 86, then carry on: 865 / 91

Let's proceed to step 6:
When dividing 865 by 91, we get 9 with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 9519.0
If we subtract 819 from 865, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 7:
If we divide 460 by 91, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 9519.5
The remainder is 5 after subtracting 455 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
50 divided by 91 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 9519.5
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
The number 91 fits into 500 5 times, leaving a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 9519.505
The remainder is 45 after subtracting 455 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 10:
91 can be fit into 450 4 times, resulting in a remainder of 86.
Use 4 as the next digit of our solution. 
Result so far: 9519.5054
If we subtract 364 from 450, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 11:
860 divided by 91 is 9 with a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 9519.50549
Subtract 819 from 860 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 12:
The number 91 fits into 410 4 times, leaving a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 9519.505494
Subtract 364 from 410 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 13:
91 goes into 460 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 9519.5054945
Subtract 455 from 460 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 14:
50 divided by 91 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 9519.5054945
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 9519.5054945 with a remaining 5e-08.
