479449 ÷ 20 
We want to figure out the number of times 479449 can be divided by 20.

Advancing to step 1:
20 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 20

On to step 2:
When dividing 47 by 20, we get 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 40 from 47 and we're left with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 20

Let's proceed to step 3:
79 divided by 20 is 3 with a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtracting 60 from 79 leaves us with 19.
Append the next digit (4) from the dividend to 19 and continue with: 194 / 20

Step 4:
194 divided by 20 is 9 with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 239.0
The remainder is 14 after subtracting 180 from 194.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 20

Moving on to step 5:
20 goes into 144 7 times with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 2397.0
Subtracting 140 from 144 leaves us with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 20

Step 6:
The number 20 fits into 49 2 times, leaving a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 23972.0
The remainder is 9 after subtracting 40 from 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
20 goes into 90 4 times with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 23972.4
The remainder is 10 after subtracting 80 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
20 goes into 100 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 23972.45
If we take 100 away from 100, 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 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 23972.45
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.

Step 10:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 23972.45
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.

In conclusion, the division gives 23972.45 with a balance of 0.0.
