We look at the division of 448138 by 20 
We want to divide 448138 by 20.

Advancing to step 1:
The number 20 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 20

Step 2:
The number 20 fits into 44 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 40 away from 44, we end up with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 20

Moving on to step 3:
When dividing 48 by 20, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtracting 40 from 48 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 20

Going ahead to step 4:
81 divided by 20 is 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 224.0
Subtracting 80 from 81 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 20

Advancing to step 5:
20 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 2240.0
Deduct 0 from 13 and we're left with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 20

Step 6:
20 can be fit into 138 6 times, resulting in a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 22406.0
If we subtract 120 from 138, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
The number 20 fits into 180 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 22406.9
If we subtract 180 from 180, 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.

Advancing to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 22406.9
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.

Going ahead to step 9:
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: 22406.9
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.

After the division, we end up with 22406.9 and a remainder of 0.0.
