We look at the division of 804223 by 20 
Our goal is to divide 804223 by 20.

Let's proceed to step 1:
When dividing 8 by 20, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 20

Going ahead to step 2:
80 divided by 20 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 80 from 80 to get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 20

Going ahead to step 3:
4 divided by 20 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 20

On to step 4:
20 goes into 42 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 402.0
If we take 40 away from 42, we end up with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 20

Going ahead to step 5:
20 goes into 22 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 4021.0
The remainder is 2 after subtracting 20 from 22.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 20

Moving on to step 6:
23 divided by 20 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 40211.0
Deduct 20 from 23 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
The number 20 fits into 30 1 times, leaving a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 40211.1
Subtract 20 from 30 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.

Advancing to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 40211.15
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.

Let's proceed to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 40211.15
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.

On to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40211.15
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.

The final outcome is 40211.15, with a leftover of 0.0.
