We're dividing 89908 by 20 
We want to divide 89908 by 20.

Advancing to step 1:
If we divide 8 by 20, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 20

Advancing to step 2:
When dividing 89 by 20, we get 4 with a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 80 away from 89, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 20

Moving on to step 3:
The number 20 fits into 99 4 times, leaving a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 44.0
If we subtract 80 from 99, we get 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 20

Advancing to step 4:
20 goes into 190 9 times with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 449.0
If we subtract 180 from 190, we get 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 20

Let's proceed to step 5:
108 divided by 20 is 5 with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 4495.0
The remainder is 8 after subtracting 100 from 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 6:
The number 20 fits into 80 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4495.4
Subtract 80 from 80 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4495.4
Subtracting 0 from 0 leaves us 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.

On to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4495.4
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 4495.4 with a remaining 0.0.
