We look at the division of 811900 by 91 
Our goal is to divide 811900 by 91.

Let's proceed to step 1:
When dividing 8 by 91, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 91

On to step 2:
When dividing 81 by 91, we get 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Include the next digit (1) from the dividend after 81, then repeat: 811 / 91

Let's proceed to step 3:
The number 91 fits into 811 8 times, leaving a remainder of 83.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 728 from 811 leaves us with 83.
Fetch the next digit (9) from the dividend, attach it to 83 and continue: 839 / 91

Advancing to step 4:
If we divide 839 by 91, we get 9 and a remainder of 20.
The next digit of our result is 9. 
Result so far: 89.0
Subtracting 819 from 839 leaves us with 20.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 91

On to step 5:
91 goes into 200 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 892.0
Deduct 182 from 200 and we're left with 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 91

Going ahead to step 6:
180 divided by 91 is 1 with a remainder of 89.
The next digit of our result is 1. 
Result so far: 8921.0
Deduct 91 from 180 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 7:
If we divide 890 by 91, we get 9 and a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 8921.9
Subtract 819 from 890 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 8:
710 divided by 91 is 7 with a remainder of 73.
The next digit of our result is 7. 
Result so far: 8921.97
Deduct 637 from 710 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 9:
The number 91 fits into 730 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 8921.978
If we take 728 away from 730, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
20 divided by 91 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 8921.978
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
200 divided by 91 is 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 8921.97802
The remainder is 18 after subtracting 182 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 12:
180 divided by 91 is 1 with a remainder of 89.
Record the quotient 1 as the next digit in the result. 
Result so far: 8921.978021
Subtracting 91 from 180 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 13:
91 goes into 890 9 times with a remainder of 71.
The number 9 becomes the next digit in our result. 
Result so far: 8921.9780219
The remainder is 71 after subtracting 819 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 14:
91 can be fit into 710 7 times, resulting in a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 8921.97802197
Subtract 637 from 710 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

In conclusion, the division gives 8921.97802197 with a balance of 7.3e-08.
