We look at the division of 438008 by 20 
Let's see how many times 20 fits into 438008.

Let's proceed to step 1:
20 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 20

Advancing to step 2:
20 can be fit into 43 2 times, resulting in a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 40 from 43 and we're left with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 20

Going ahead to step 3:
38 divided by 20 is 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 20 from 38 and we're left with 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 20

On to step 4:
If we divide 180 by 20, we get 9 and a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 219.0
The remainder is 0 after subtracting 180 from 180.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 20

On to step 5:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2190.0
The remainder is 0 after subtracting 0 from 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 20

On to step 6:
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: 21900.0
Subtract 0 from 8 to 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.

Let's proceed to step 7:
20 goes into 80 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 21900.4
If we take 80 away from 80, we end up 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 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 21900.4
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.

Let's proceed to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 21900.4
If we subtract 0 from 0, 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.

After the division, we end up with 21900.4 and a remainder of 0.0.
