490096 ÷ 20 
The aim is to understand the frequency of 20 in 490096.

Moving on to step 1:
When dividing 4 by 20, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 20

Moving on to step 2:
20 can be fit into 49 2 times, resulting in a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 40 away from 49, we end up with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 20

Advancing to step 3:
When dividing 90 by 20, we get 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 24.0
The remainder is 10 after subtracting 80 from 90.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 20

Going ahead to step 4:
20 can be fit into 100 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 245.0
If we take 100 away from 100, we end up with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 20

On to step 5:
9 divided by 20 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 2450.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 20

Let's proceed to step 6:
When dividing 96 by 20, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 24504.0
Subtract 80 from 96 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
When dividing 160 by 20, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 24504.8
The remainder is 0 after subtracting 160 from 160.
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:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 24504.8
Subtract 0 from 0 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.

Advancing to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 24504.8
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.

The quotient of the division is 24504.8, and the remainder is 0.0.
