We look at the division of 823040 by 20 
Let's see how many times 20 fits into 823040.

Moving on to 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
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 20

Let's proceed to step 2:
When dividing 82 by 20, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 80 from 82, we get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 20

On to step 3:
20 can be fit into 23 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 41.0
The remainder is 3 after subtracting 20 from 23.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 20

Moving on to step 4:
When dividing 30 by 20, we get 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 411.0
Deduct 20 from 30 and we're left with 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 20

Step 5:
20 goes into 104 5 times with a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 4115.0
If we take 100 away from 104, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 20

Advancing to step 6:
20 can be fit into 40 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 41152.0
Subtract 40 from 40 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.

Let's proceed to step 7:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 41152.0
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.

Let's proceed to step 8:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 41152.0
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.

After the division, we end up with 41152.0 and a remainder of 0.0.
