20978075 divided by 991 
Our goal is to divide 20978075 by 991.

Going ahead to step 1:
2 divided by 991 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 991

Going ahead to step 2:
When dividing 20 by 991, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 991

Step 3:
991 goes into 209 0 times with a remainder of 209.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 209 leaves us with 209.
Take the next digit (7) from the dividend and append it to 209, then repeat: 2097 / 991

Step 4:
991 goes into 2097 2 times with a remainder of 115.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 1982 away from 2097, we end up with 115.
Append the next digit (8) from the dividend to 115 and continue with: 1158 / 991

Moving on to step 5:
If we divide 1158 by 991, we get 1 and a remainder of 167.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Deduct 991 from 1158 and we're left with 167.
Include the next digit (0) from the dividend after 167, then repeat: 1670 / 991

Going ahead to step 6:
991 can be fit into 1670 1 times, resulting in a remainder of 679.
Put 1 as the next digit of the answer. 
Result so far: 211.0
Subtracting 991 from 1670 leaves us with 679.
Include the next digit (7) from the dividend after 679, then repeat: 6797 / 991

Advancing to step 7:
991 goes into 6797 6 times with a remainder of 851.
Record the quotient 6 as the next digit in the result. 
Result so far: 2116.0
Subtracting 5946 from 6797 leaves us with 851.
Bring next digit (5) of the dividend behind the 851 and repeat the process: 8515 / 991

Going ahead to step 8:
8515 divided by 991 is 8 with a remainder of 587.
Use 8 as the next digit of our solution. 
Result so far: 21168.0
If we take 7928 away from 8515, we end up with 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Step 9:
The number 991 fits into 5870 5 times, leaving a remainder of 915.
Use 5 as the next digit of our solution. 
Result so far: 21168.5
If we subtract 4955 from 5870, we get 915.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9150, and continue the process.

On to step 10:
When dividing 9150 by 991, we get 9 with a remainder of 231.
The next digit of our result is 9. 
Result so far: 21168.59
If we subtract 8919 from 9150, we get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Moving on to step 11:
991 goes into 2310 2 times with a remainder of 328.
The next digit of our result is 2. 
Result so far: 21168.592
The remainder is 328 after subtracting 1982 from 2310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 12:
The number 991 fits into 3280 3 times, leaving a remainder of 307.
Write down 3 as next digit of the result. 
Result so far: 21168.5923
If we subtract 2973 from 3280, we get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

On to step 13:
The number 991 fits into 3070 3 times, leaving a remainder of 97.
The number 3 becomes the next digit in our result. 
Result so far: 21168.59233
Deduct 2973 from 3070 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

The final outcome is 21168.59233, with a leftover of 9.7e-05.
