We look at the division of 447960 by 20 
Let's see how many times 20 fits into 447960.

On to step 1:
20 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (4) from the dividend to 4 and continue with: 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.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 20

Let's proceed to step 3:
47 divided by 20 is 2 with a remainder of 7.
The next digit of our result is 2. 
Result so far: 22.0
Deduct 40 from 47 and we're left with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 20

Moving on to step 4:
20 can be fit into 79 3 times, resulting in a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 223.0
Deduct 60 from 79 and we're left with 19.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 20

Step 5:
When dividing 196 by 20, we get 9 with a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 2239.0
Deduct 180 from 196 and we're left with 16.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 20

Advancing to step 6:
When dividing 160 by 20, we get 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 22398.0
Subtract 160 from 160 to 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 7:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 22398.0
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.

Moving on to step 8:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 22398.0
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 22398.0 and a remainder of 0.0.
