We divide 819900 by 91
We want to divide 819900 by 91.

Let's proceed to step 1:
If we divide 8 by 91, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 91

On to step 2:
91 can be fit into 81 0 times, resulting in a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Fetch the next digit (9) from the dividend, attach it to 81 and continue: 819 / 91

Step 3:
819 divided by 91 is 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 0 after subtracting 819 from 819.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 91

Advancing to step 4:
91 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 90.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 91

Moving on to step 5:
91 goes into 90 0 times with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 900.0
If we subtract 0 from 90, we get 90.
Grab the next digit (0) from the dividend, add it to 90, then carry on: 900 / 91

Moving on to step 6:
91 can be fit into 900 9 times, resulting in a remainder of 81.
Use 9 as the next digit of our solution. 
Result so far: 9009.0
Subtracting 819 from 900 leaves us 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.

Step 7:
If we divide 810 by 91, we get 8 and a remainder of 82.
Record the quotient 8 as the next digit in the result. 
Result so far: 9009.8
The remainder is 82 after subtracting 728 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 8:
91 can be fit into 820 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 9009.89
Subtract 819 from 820 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
10 divided by 91 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 9009.89
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
100 divided by 91 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 9009.8901
If we subtract 91 from 100, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
The number 91 fits into 90 0 times, leaving a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 9009.8901
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 12:
900 divided by 91 is 9 with a remainder of 81.
Put 9 as the next digit of the answer. 
Result so far: 9009.890109
The remainder is 81 after subtracting 819 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing 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: 9009.8901098
If we take 728 away from 810, we end up 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.

Moving on to step 14:
The number 91 fits into 820 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 9009.89010989
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 quotient of the division is 9009.89010989, and the remainder is 1e-09.
