304 ÷ 80 
The aim is to understand the frequency of 80 in 304.

Let's proceed to step 1:
80 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 80

Advancing to step 2:
30 divided by 80 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Include the next digit (4) from the dividend after 30, then repeat: 304 / 80

Going ahead to step 3:
If we divide 304 by 80, we get 3 and a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 240 from 304 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 4:
80 can be fit into 640 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 3.8
The remainder is 0 after subtracting 640 from 640.
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 5:
If we divide 0 by 80, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3.8
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.

Let's proceed to step 6:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3.8
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 3.8 and a remainder of 0.0.
