We look at the division of 449644 by 20 
Let's see how many times 20 fits into 449644.

Moving on to step 1:
20 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 20

Let's proceed to step 2:
20 can be fit into 44 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 40 from 44 and we're left with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 20

Advancing to step 3:
49 divided by 20 is 2 with a remainder of 9.
The next digit of our result is 2. 
Result so far: 22.0
Subtracting 40 from 49 leaves us with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 20

On to step 4:
20 goes into 96 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 224.0
Subtract 80 from 96 to get 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 20

On to step 5:
20 goes into 164 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 2248.0
Deduct 160 from 164 and we're left with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 20

Step 6:
When dividing 44 by 20, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 22482.0
Subtracting 40 from 44 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
20 can be fit into 40 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 22482.2
Subtracting 40 from 40 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.

Going ahead to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 22482.2
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:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 22482.2
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.

The final result is 22482.2 with a remainder of 0.0.
