We look at the division of 818387 by 91 
We want to figure out the number of times 818387 can be divided by 91.

Step 1:
The number 91 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 91

Going ahead to step 2:
If we divide 81 by 91, we get 0 and a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Bring next digit (8) of the dividend behind the 81 and repeat the process: 818 / 91

Step 3:
The number 91 fits into 818 8 times, leaving a remainder of 90.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 728 from 818 and we're left with 90.
Append the next digit (3) from the dividend to 90 and continue with: 903 / 91

On to step 4:
When dividing 903 by 91, we get 9 with a remainder of 84.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
Subtracting 819 from 903 leaves us with 84.
Fetch the next digit (8) from the dividend, attach it to 84 and continue: 848 / 91

Advancing to step 5:
When dividing 848 by 91, we get 9 with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 899.0
Deduct 819 from 848 and we're left with 29.
Fetch the next digit (7) from the dividend, attach it to 29 and continue: 297 / 91

On to step 6:
297 divided by 91 is 3 with a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 8993.0
If we take 273 away from 297, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
91 can be fit into 240 2 times, resulting in a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 8993.2
The remainder is 58 after subtracting 182 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 8:
When dividing 580 by 91, we get 6 with a remainder of 34.
The next digit of our result is 6. 
Result so far: 8993.26
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
When dividing 340 by 91, we get 3 with a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 8993.263
Subtract 273 from 340 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 10:
The number 91 fits into 670 7 times, leaving a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 8993.2637
If we subtract 637 from 670, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 11:
When dividing 330 by 91, we get 3 with a remainder of 57.
The next digit of our result is 3. 
Result so far: 8993.26373
If we subtract 273 from 330, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 12:
570 divided by 91 is 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 8993.263736
If we subtract 546 from 570, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
When dividing 240 by 91, we get 2 with a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 8993.2637362
If we subtract 182 from 240, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 14:
91 goes into 580 6 times with a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 8993.26373626
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final result is 8993.26373626 with a remainder of 3.4e-08.
