We divide 448492 by 20
We want to figure out the number of times 448492 can be divided by 20.

Going ahead to step 1:
4 divided by 20 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 20

Let's proceed to step 2:
The number 20 fits into 44 2 times, leaving 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.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 20

On to step 3:
If we divide 48 by 20, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
The remainder is 8 after subtracting 40 from 48.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 20

Advancing to step 4:
When dividing 84 by 20, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 224.0
Deduct 80 from 84 and we're left with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 20

Step 5:
When dividing 49 by 20, we get 2 with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 2242.0
Deduct 40 from 49 and we're left with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 20

Let's proceed to step 6:
92 divided by 20 is 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 22424.0
Subtract 80 from 92 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
20 can be fit into 120 6 times, resulting in a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 22424.6
Subtracting 120 from 120 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.

Advancing to step 8:
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: 22424.6
If we take 0 away from 0, 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.

Going ahead to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 22424.6
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.

Our division results in 22424.6 with a remaining 0.0.
