We look at the division of 8871 by 20 
We're looking to find how many times 20 goes into 8871.

On to step 1:
20 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 20

Advancing to step 2:
The number 20 fits into 88 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 4.0
If we take 80 away from 88, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 20

On to step 3:
87 divided by 20 is 4 with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 44.0
If we take 80 away from 87, we end up with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 20

Going ahead to step 4:
71 divided by 20 is 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 443.0
If we take 60 away from 71, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 5:
If we divide 110 by 20, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 443.5
The remainder is 10 after subtracting 100 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 6:
When dividing 100 by 20, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 443.55
If we take 100 away from 100, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 443.55, and the remainder is 0.0.
