We look at the division of 447388 by 20 
Our goal is to divide 447388 by 20.

Step 1:
When dividing 4 by 20, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 20

Going ahead to step 2:
44 divided by 20 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 40 from 44 leaves us with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 20

Step 3:
47 divided by 20 is 2 with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Subtract 40 from 47 to get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 20

Advancing to step 4:
20 goes into 73 3 times with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 223.0
If we take 60 away from 73, we end up with 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 20

On to step 5:
138 divided by 20 is 6 with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 2236.0
The remainder is 18 after subtracting 120 from 138.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 20

Step 6:
188 divided by 20 is 9 with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 22369.0
If we subtract 180 from 188, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
When dividing 80 by 20, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 22369.4
Subtracting 80 from 80 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:
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: 22369.4
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.

Advancing to step 9:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 22369.4
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 final outcome is 22369.4, with a leftover of 0.0.
