We look at the division of 91197787 by 85 
Let's see how many times 85 fits into 91197787.

Going ahead to step 1:
85 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 85

Let's proceed to step 2:
91 divided by 85 is 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 6 after subtracting 85 from 91.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 85

Advancing to step 3:
61 divided by 85 is 0 with a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 61, we end up with 61.
Include the next digit (9) from the dividend after 61, then repeat: 619 / 85

Going ahead to step 4:
85 can be fit into 619 7 times, resulting in a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 107.0
The remainder is 24 after subtracting 595 from 619.
Append the next digit (7) from the dividend to 24 and continue with: 247 / 85

Advancing to step 5:
If we divide 247 by 85, we get 2 and a remainder of 77.
The next digit of our result is 2. 
Result so far: 1072.0
Subtract 170 from 247 to get 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 85

Going ahead to step 6:
When dividing 777 by 85, we get 9 with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 10729.0
If we subtract 765 from 777, we get 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 85

Let's proceed to step 7:
The number 85 fits into 128 1 times, leaving a remainder of 43.
The next digit of our result is 1. 
Result so far: 107291.0
If we subtract 85 from 128, we get 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 85

Advancing to step 8:
If we divide 437 by 85, we get 5 and a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 1072915.0
If we subtract 425 from 437, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
If we divide 120 by 85, we get 1 and a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 1072915.1
Subtract 85 from 120 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 10:
85 goes into 350 4 times with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 1072915.14
If we subtract 340 from 350, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
The number 85 fits into 100 1 times, leaving a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1072915.141
The remainder is 15 after subtracting 85 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 12:
85 goes into 150 1 times with a remainder of 65.
The next digit of our result is 1. 
Result so far: 1072915.1411
Subtracting 85 from 150 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Our division results in 1072915.1411 with a remaining 0.00065.
