We divide 449380 by 20
We're looking to find how many times 20 goes into 449380.

Moving on to step 1:
20 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 20

On to step 2:
If we divide 44 by 20, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 40 from 44 leaves us with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 20

Moving on 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
If we subtract 40 from 49, we get 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 20

Moving on to step 4:
20 can be fit into 93 4 times, resulting in a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 224.0
The remainder is 13 after subtracting 80 from 93.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 20

Step 5:
When dividing 138 by 20, we get 6 with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 2246.0
If we take 120 away from 138, we end up with 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 20

Moving on to step 6:
180 divided by 20 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 22469.0
If we take 180 away from 180, 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.

Moving on to step 7:
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: 22469.0
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.

Step 8:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 22469.0
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 22469.0, with a leftover of 0.0.
