We're dividing 304048 by 20 
The aim is to understand the frequency of 20 in 304048.

Going ahead to step 1:
20 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 20

Step 2:
20 can be fit into 30 1 times, resulting in a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 20 away from 30, we end up with 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 20

Advancing to step 3:
The number 20 fits into 104 5 times, leaving a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 100 from 104 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 20

Let's proceed to step 4:
The number 20 fits into 40 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 152.0
If we subtract 40 from 40, we get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 20

Advancing to step 5:
20 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 1520.0
Subtract 0 from 4 to get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 20

Advancing to step 6:
20 goes into 48 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 15202.0
The remainder is 8 after subtracting 40 from 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
20 goes into 80 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 15202.4
If we subtract 80 from 80, 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.

Let's proceed to step 8:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 15202.4
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.

On to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 15202.4
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 result is 15202.4 with a remainder of 0.0.
