Let's divide 808908 by 20
We're looking to find how many times 20 goes into 808908.

Step 1:
When dividing 8 by 20, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 20

Advancing to step 2:
When dividing 80 by 20, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 80 from 80, we get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 20

Advancing to step 3:
20 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we take 0 away from 8, we end up with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 20

Let's proceed to step 4:
When dividing 89 by 20, we get 4 with a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 404.0
Subtract 80 from 89 to get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 20

On to step 5:
90 divided by 20 is 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 4044.0
If we take 80 away from 90, we end up with 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 20

Let's proceed to step 6:
108 divided by 20 is 5 with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 40445.0
If we take 100 away from 108, we end up with 8.
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 7:
20 can be fit into 80 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 40445.4
The remainder is 0 after subtracting 80 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 40445.4
Deduct 0 from 0 and we're left 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.

Moving on to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 40445.4
If we subtract 0 from 0, we 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.

The final result is 40445.4 with a remainder of 0.0.
