We look at the division of 91819310 by 91 
We want to figure out the number of times 91819310 can be divided by 91.

On to step 1:
9 divided by 91 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 91

Going ahead to step 2:
When dividing 91 by 91, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 0 after subtracting 91 from 91.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 91

Moving on to step 3:
8 divided by 91 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 91

On to step 4:
If we divide 81 by 91, we get 0 and a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 100.0
The remainder is 81 after subtracting 0 from 81.
Include the next digit (9) from the dividend after 81, then repeat: 819 / 91

Moving on to step 5:
91 can be fit into 819 9 times, resulting in a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 1009.0
Subtracting 819 from 819 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 91

On to step 6:
The number 91 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 10090.0
If we take 0 away from 3, we end up with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 91

Going ahead to step 7:
91 can be fit into 31 0 times, resulting in a remainder of 31.
The next digit of our result is 0. 
Result so far: 100900.0
Subtracting 0 from 31 leaves us with 31.
Append the next digit (0) from the dividend to 31 and continue with: 310 / 91

Let's proceed to step 8:
The number 91 fits into 310 3 times, leaving a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 1009003.0
The remainder is 37 after subtracting 273 from 310.
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 9:
If we divide 370 by 91, we get 4 and a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 1009003.4
If we take 364 away from 370, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
91 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 1009003.4
The remainder is 60 after subtracting 0 from 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 11:
If we divide 600 by 91, we get 6 and a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 1009003.406
If we subtract 546 from 600, we get 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 12:
The number 91 fits into 540 5 times, leaving a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 1009003.4065
The remainder is 85 after subtracting 455 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 13:
850 divided by 91 is 9 with a remainder of 31.
The next digit of our result is 9. 
Result so far: 1009003.40659
If we subtract 819 from 850, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 14:
If we divide 310 by 91, we get 3 and a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 1009003.406593
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.

On to step 15:
If we divide 370 by 91, we get 4 and a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 1009003.4065934
If we take 364 away from 370, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 16:
91 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 1009003.4065934
Subtract 0 from 60 to get 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 1009003.4065934 and a remainder of 6e-08.
