812893 ÷ 91 
We're looking to find how many times 91 goes into 812893.

Moving on to step 1:
If we divide 8 by 91, we get 0 and 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.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 91

Advancing to step 2:
If we divide 81 by 91, we get 0 and a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Fetch the next digit (2) from the dividend, attach it to 81 and continue: 812 / 91

Let's proceed to step 3:
When dividing 812 by 91, we get 8 with a remainder of 84.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 728 from 812, we get 84.
Include the next digit (8) from the dividend after 84, then repeat: 848 / 91

Step 4:
If we divide 848 by 91, we get 9 and a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 89.0
If we take 819 away from 848, we end up with 29.
Take the next digit (9) from the dividend and append it to 29, then repeat: 299 / 91

Going ahead to step 5:
The number 91 fits into 299 3 times, leaving a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 893.0
Deduct 273 from 299 and we're left with 26.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 91

Moving on to step 6:
The number 91 fits into 263 2 times, leaving a remainder of 81.
Record the quotient 2 as the next digit in the result. 
Result so far: 8932.0
If we subtract 182 from 263, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 7:
When dividing 810 by 91, we get 8 with a remainder of 82.
Put 8 as the next digit of the answer. 
Result so far: 8932.8
Subtracting 728 from 810 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 8:
820 divided by 91 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 8932.89
Subtracting 819 from 820 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
91 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 8932.89
If we subtract 0 from 10, 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.

On to step 10:
When dividing 100 by 91, we get 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 8932.8901
The remainder is 9 after subtracting 91 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 11:
90 divided by 91 is 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 8932.8901
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 12:
The number 91 fits into 900 9 times, leaving a remainder of 81.
Use 9 as the next digit of our solution. 
Result so far: 8932.890109
Deduct 819 from 900 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 13:
91 goes into 810 8 times with a remainder of 82.
The next digit of our result is 8. 
Result so far: 8932.8901098
Deduct 728 from 810 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 14:
91 can be fit into 820 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 8932.89010989
Subtracting 819 from 820 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 8932.89010989, with a leftover of 1e-09.
