We're dividing 81072787 by 91 
We want to divide 81072787 by 91.

On to step 1:
91 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 91

Going ahead to step 2:
91 goes into 81 0 times with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Fetch the next digit (0) from the dividend, attach it to 81 and continue: 810 / 91

Let's proceed to step 3:
The number 91 fits into 810 8 times, leaving a remainder of 82.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 728 from 810, we get 82.
Include the next digit (7) from the dividend after 82, then repeat: 827 / 91

On to step 4:
The number 91 fits into 827 9 times, leaving a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
If we subtract 819 from 827, we get 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 91

On to step 5:
91 goes into 82 0 times with a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 890.0
Deduct 0 from 82 and we're left with 82.
Append the next digit (7) from the dividend to 82 and continue with: 827 / 91

Let's proceed to step 6:
91 can be fit into 827 9 times, resulting in a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 8909.0
If we subtract 819 from 827, we get 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 91

Step 7:
When dividing 88 by 91, we get 0 with a remainder of 88.
Use 0 as the next digit of our solution. 
Result so far: 89090.0
If we subtract 0 from 88, we get 88.
Bring next digit (7) of the dividend behind the 88 and repeat the process: 887 / 91

Let's proceed to step 8:
887 divided by 91 is 9 with a remainder of 68.
The next digit of our result is 9. 
Result so far: 890909.0
If we subtract 819 from 887, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 9:
The number 91 fits into 680 7 times, leaving a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 890909.7
Deduct 637 from 680 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 10:
If we divide 430 by 91, we get 4 and a remainder of 66.
The next digit of our result is 4. 
Result so far: 890909.74
If we take 364 away from 430, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 11:
The number 91 fits into 660 7 times, leaving a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 890909.747
Subtract 637 from 660 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 12:
91 can be fit into 230 2 times, resulting in a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 890909.7472
Deduct 182 from 230 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
91 can be fit into 480 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 890909.74725
If we take 455 away from 480, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 14:
The number 91 fits into 250 2 times, leaving a remainder of 68.
The next digit of our result is 2. 
Result so far: 890909.747252
The remainder is 68 after subtracting 182 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 15:
The number 91 fits into 680 7 times, leaving a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 890909.7472527
Subtract 637 from 680 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 16:
91 can be fit into 430 4 times, resulting in a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 890909.74725274
Deduct 364 from 430 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The quotient of the division is 890909.74725274, and the remainder is 6.6e-08.
