Let's divide 328848 by 20
The aim is to understand the frequency of 20 in 328848.

On to step 1:
3 divided by 20 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 20

Advancing to step 2:
The number 20 fits into 32 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 20 from 32 to get 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 20

On to step 3:
20 goes into 128 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we subtract 120 from 128, we get 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 20

On to step 4:
20 can be fit into 88 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 164.0
Subtracting 80 from 88 leaves us with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 20

Going ahead to step 5:
If we divide 84 by 20, we get 4 and a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 1644.0
Deduct 80 from 84 and we're left with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 20

Advancing to step 6:
20 can be fit into 48 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 16442.0
If we subtract 40 from 48, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
The number 20 fits into 80 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 16442.4
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.

Moving on to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 16442.4
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.

Let's proceed to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 16442.4
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.

After the division, we end up with 16442.4 and a remainder of 0.0.
