We look at the division of 20880952 by 623 
We want to divide 20880952 by 623.

On to step 1:
The number 623 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 623

Step 2:
When dividing 20 by 623, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 623

Advancing to step 3:
623 goes into 208 0 times with a remainder of 208.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 208 and we're left with 208.
Grab the next digit (8) from the dividend, add it to 208, then carry on: 2088 / 623

On to step 4:
If we divide 2088 by 623, we get 3 and a remainder of 219.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 1869 away from 2088, we end up with 219.
Take the next digit (0) from the dividend and append it to 219, then repeat: 2190 / 623

Moving on to step 5:
623 can be fit into 2190 3 times, resulting in a remainder of 321.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we subtract 1869 from 2190, we get 321.
Bring next digit (9) of the dividend behind the 321 and repeat the process: 3219 / 623

Going ahead to step 6:
3219 divided by 623 is 5 with a remainder of 104.
Put 5 as the next digit of the answer. 
Result so far: 335.0
If we take 3115 away from 3219, we end up with 104.
Bring next digit (5) of the dividend behind the 104 and repeat the process: 1045 / 623

Step 7:
When dividing 1045 by 623, we get 1 with a remainder of 422.
Write down 1 as next digit of the result. 
Result so far: 3351.0
If we subtract 623 from 1045, we get 422.
Append the next digit (2) from the dividend to 422 and continue with: 4222 / 623

Moving on to step 8:
4222 divided by 623 is 6 with a remainder of 484.
Record the quotient 6 as the next digit in the result. 
Result so far: 33516.0
Subtracting 3738 from 4222 leaves us with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

On to step 9:
4840 divided by 623 is 7 with a remainder of 479.
Record the quotient 7 as the next digit in the result. 
Result so far: 33516.7
If we take 4361 away from 4840, we end up with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Moving on to step 10:
623 goes into 4790 7 times with a remainder of 429.
Write down 7 as next digit of the result. 
Result so far: 33516.77
Deduct 4361 from 4790 and we're left with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

The final outcome is 33516.77, with a leftover of 0.429.
