We divide 80805022 by 991
Our goal is to divide 80805022 by 991.

Moving on to step 1:
When dividing 8 by 991, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 991

On to step 2:
When dividing 80 by 991, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Include the next digit (8) from the dividend after 80, then repeat: 808 / 991

Going ahead to step 3:
808 divided by 991 is 0 with a remainder of 808.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 808 to get 808.
Take the next digit (0) from the dividend and append it to 808, then repeat: 8080 / 991

Going ahead to step 4:
If we divide 8080 by 991, we get 8 and a remainder of 152.
The next digit of our result is 8. 
Result so far: 8.0
If we take 7928 away from 8080, we end up with 152.
Grab the next digit (5) from the dividend, add it to 152, then carry on: 1525 / 991

Moving on to step 5:
The number 991 fits into 1525 1 times, leaving a remainder of 534.
Write down 1 as next digit of the result. 
Result so far: 81.0
If we take 991 away from 1525, we end up with 534.
Take the next digit (0) from the dividend and append it to 534, then repeat: 5340 / 991

On to step 6:
When dividing 5340 by 991, we get 5 with a remainder of 385.
Put 5 as the next digit of the answer. 
Result so far: 815.0
Subtracting 4955 from 5340 leaves us with 385.
Fetch the next digit (2) from the dividend, attach it to 385 and continue: 3852 / 991

Step 7:
The number 991 fits into 3852 3 times, leaving a remainder of 879.
The number 3 becomes the next digit in our result. 
Result so far: 8153.0
If we subtract 2973 from 3852, we get 879.
Append the next digit (2) from the dividend to 879 and continue with: 8792 / 991

Step 8:
991 can be fit into 8792 8 times, resulting in a remainder of 864.
The number 8 becomes the next digit in our result. 
Result so far: 81538.0
Subtracting 7928 from 8792 leaves us with 864.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8640, and continue the process.

Step 9:
991 goes into 8640 8 times with a remainder of 712.
Put 8 as the next digit of the answer. 
Result so far: 81538.8
Subtracting 7928 from 8640 leaves us with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Let's proceed to step 10:
7120 divided by 991 is 7 with a remainder of 183.
Put 7 as the next digit of the answer. 
Result so far: 81538.87
Subtracting 6937 from 7120 leaves us with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Let's proceed to step 11:
If we divide 1830 by 991, we get 1 and a remainder of 839.
Write down 1 as next digit of the result. 
Result so far: 81538.871
Subtract 991 from 1830 to get 839.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8390, and continue the process.

Going ahead to step 12:
The number 991 fits into 8390 8 times, leaving a remainder of 462.
The next digit of our result is 8. 
Result so far: 81538.8718
Subtract 7928 from 8390 to get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Going ahead to step 13:
If we divide 4620 by 991, we get 4 and a remainder of 656.
The next digit of our result is 4. 
Result so far: 81538.87184
The remainder is 656 after subtracting 3964 from 4620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Advancing to step 14:
When dividing 6560 by 991, we get 6 with a remainder of 614.
Write down 6 as next digit of the result. 
Result so far: 81538.871846
Deduct 5946 from 6560 and we're left with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Moving on to step 15:
When dividing 6140 by 991, we get 6 with a remainder of 194.
Put 6 as the next digit of the answer. 
Result so far: 81538.8718466
Subtracting 5946 from 6140 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

The final result is 81538.8718466 with a remainder of 1.94e-06.
