20631988 divided by 879 
Our goal is to divide 20631988 by 879.

Moving on to step 1:
2 divided by 879 is 0 with a remainder of 2.
The number 0 becomes the next digit in our 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 / 879

Let's proceed to step 2:
879 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 879

Advancing to step 3:
879 goes into 206 0 times with a remainder of 206.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 206, we end up with 206.
Fetch the next digit (3) from the dividend, attach it to 206 and continue: 2063 / 879

Going ahead to step 4:
The number 879 fits into 2063 2 times, leaving a remainder of 305.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1758 from 2063, we get 305.
Take the next digit (1) from the dividend and append it to 305, then repeat: 3051 / 879

Step 5:
If we divide 3051 by 879, we get 3 and a remainder of 414.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtract 2637 from 3051 to get 414.
Include the next digit (9) from the dividend after 414, then repeat: 4149 / 879

Let's proceed to step 6:
The number 879 fits into 4149 4 times, leaving a remainder of 633.
The next digit of our result is 4. 
Result so far: 234.0
Subtracting 3516 from 4149 leaves us with 633.
Bring next digit (8) of the dividend behind the 633 and repeat the process: 6338 / 879

Going ahead to step 7:
The number 879 fits into 6338 7 times, leaving a remainder of 185.
Use 7 as the next digit of our solution. 
Result so far: 2347.0
Subtracting 6153 from 6338 leaves us with 185.
Take the next digit (8) from the dividend and append it to 185, then repeat: 1858 / 879

Moving on to step 8:
1858 divided by 879 is 2 with a remainder of 100.
Record the quotient 2 as the next digit in the result. 
Result so far: 23472.0
The remainder is 100 after subtracting 1758 from 1858.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 9:
When dividing 1000 by 879, we get 1 with a remainder of 121.
Put 1 as the next digit of the answer. 
Result so far: 23472.1
Subtract 879 from 1000 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Going ahead to step 10:
879 goes into 1210 1 times with a remainder of 331.
The next digit of our result is 1. 
Result so far: 23472.11
Subtracting 879 from 1210 leaves us with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Our division results in 23472.11 with a remaining 0.331.
