Let's divide 811666 by 91
Let's see how many times 91 fits into 811666.

Going ahead to step 1:
When dividing 8 by 91, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 91

Moving on to step 2:
The number 91 fits into 81 0 times, leaving a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Bring next digit (1) of the dividend behind the 81 and repeat the process: 811 / 91

Step 3:
When dividing 811 by 91, we get 8 with a remainder of 83.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 728 from 811 and we're left with 83.
Take the next digit (6) from the dividend and append it to 83, then repeat: 836 / 91

On to step 4:
91 goes into 836 9 times with a remainder of 17.
The next digit of our result is 9. 
Result so far: 89.0
If we subtract 819 from 836, we get 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 91

On to step 5:
91 can be fit into 176 1 times, resulting in a remainder of 85.
Record the quotient 1 as the next digit in the result. 
Result so far: 891.0
If we take 91 away from 176, we end up with 85.
Take the next digit (6) from the dividend and append it to 85, then repeat: 856 / 91

Advancing to step 6:
When dividing 856 by 91, we get 9 with a remainder of 37.
The next digit of our result is 9. 
Result so far: 8919.0
If we take 819 away from 856, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
91 goes into 370 4 times with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 8919.4
The remainder is 6 after subtracting 364 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
91 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 8919.4
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
When dividing 600 by 91, we get 6 with a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 8919.406
If we take 546 away from 600, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 10:
91 can be fit into 540 5 times, resulting in a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 8919.4065
If we subtract 455 from 540, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 11:
If we divide 850 by 91, we get 9 and a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 8919.40659
The remainder is 31 after subtracting 819 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 12:
310 divided by 91 is 3 with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 8919.406593
Deduct 273 from 310 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 13:
When dividing 370 by 91, we get 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 8919.4065934
The remainder is 6 after subtracting 364 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
60 divided by 91 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 8919.4065934
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 8919.4065934 and a remainder of 6e-08.
