We're dividing 42300 by 5 
The aim is to understand the frequency of 5 in 42300.

Let's proceed to step 1:
5 goes into 4 0 times 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 (2) from the dividend after 4, then repeat: 42 / 5

On to step 2:
If we divide 42 by 5, we get 8 and a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 40 away from 42, we end up with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 5

Step 3:
5 goes into 23 4 times with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 84.0
If we subtract 20 from 23, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 5

Let's proceed to step 4:
5 can be fit into 30 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 846.0
Subtracting 30 from 30 leaves us with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 5

Advancing to step 5:
5 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8460.0
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.

Advancing to step 6:
5 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8460.0
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.

Step 7:
0 divided by 5 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8460.0
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.

Our division results in 8460.0 with a remaining 0.0.
