We look at the division of 809069 by 20 
We're looking to find how many times 20 goes into 809069.

Going ahead to step 1:
20 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 20

Going ahead to step 2:
20 can be fit into 80 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 0 after subtracting 80 from 80.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 20

Step 3:
9 divided by 20 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 40.0
If we subtract 0 from 9, we get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 20

Let's proceed to step 4:
If we divide 90 by 20, we get 4 and a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 404.0
If we subtract 80 from 90, we get 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 20

Advancing to step 5:
20 goes into 106 5 times with a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 4045.0
If we take 100 away from 106, we end up with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 20

On to step 6:
20 can be fit into 69 3 times, resulting in a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 40453.0
The remainder is 9 after subtracting 60 from 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
90 divided by 20 is 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 40453.4
Deduct 80 from 90 and we're left with 10.
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 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 40453.45
If we subtract 100 from 100, 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.

Going ahead to step 9:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40453.45
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.

Going ahead to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40453.45
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 40453.45, and the remainder is 0.0.
