20988977 ÷ 912 
We want to divide 20988977 by 912.

Advancing to step 1:
When dividing 2 by 912, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 912

Going ahead to step 2:
912 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 912

Going ahead to step 3:
912 can be fit into 209 0 times, resulting in a remainder of 209.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 209 to get 209.
Bring next digit (8) of the dividend behind the 209 and repeat the process: 2098 / 912

On to step 4:
If we divide 2098 by 912, we get 2 and a remainder of 274.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1824 from 2098 leaves us with 274.
Grab the next digit (8) from the dividend, add it to 274, then carry on: 2748 / 912

On to step 5:
The number 912 fits into 2748 3 times, leaving a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtracting 2736 from 2748 leaves us with 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 912

On to step 6:
129 divided by 912 is 0 with a remainder of 129.
The number 0 becomes the next digit in our result. 
Result so far: 230.0
If we subtract 0 from 129, we get 129.
Include the next digit (7) from the dividend after 129, then repeat: 1297 / 912

Moving on to step 7:
1297 divided by 912 is 1 with a remainder of 385.
Use 1 as the next digit of our solution. 
Result so far: 2301.0
Subtract 912 from 1297 to get 385.
Include the next digit (7) from the dividend after 385, then repeat: 3857 / 912

On to step 8:
3857 divided by 912 is 4 with a remainder of 209.
Use 4 as the next digit of our solution. 
Result so far: 23014.0
Subtract 3648 from 3857 to get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Step 9:
912 can be fit into 2090 2 times, resulting in a remainder of 266.
Write down 2 as next digit of the result. 
Result so far: 23014.2
If we take 1824 away from 2090, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Advancing to step 10:
912 goes into 2660 2 times with a remainder of 836.
Record the quotient 2 as the next digit in the result. 
Result so far: 23014.22
If we take 1824 away from 2660, we end up with 836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8360, and continue the process.

The final outcome is 23014.22, with a leftover of 0.836.
