We divide 808810 by 20
We're looking to find how many times 20 goes into 808810.

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
Subtract 0 from 8 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 20

Going ahead to step 2:
When dividing 80 by 20, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 80 from 80, we get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 20

Going ahead to step 3:
When dividing 8 by 20, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 20

Advancing to step 4:
20 can be fit into 88 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 404.0
Subtract 80 from 88 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 20

Going ahead to step 5:
If we divide 81 by 20, we get 4 and a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4044.0
If we take 80 away from 81, we end up with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 20

On to step 6:
20 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 40440.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
20 goes into 100 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 40440.5
Subtract 100 from 100 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.

Step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 40440.5
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 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 40440.5
The remainder is 0 after subtracting 0 from 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 40440.5, and the remainder is 0.0.
