We look at the division of 438356 by 5 
The aim is to understand the frequency of 5 in 438356.

On to step 1:
When dividing 4 by 5, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 5

On to step 2:
When dividing 43 by 5, we get 8 with a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 40 from 43 leaves us with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 5

Going ahead to step 3:
When dividing 38 by 5, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 87.0
If we take 35 away from 38, we end up with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 5

Moving on to step 4:
5 goes into 33 6 times with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 876.0
Subtract 30 from 33 to get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 5

Moving on to step 5:
5 can be fit into 35 7 times, resulting in a remainder of 0.
The next digit of our result is 7. 
Result so far: 8767.0
Subtract 35 from 35 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 5

Let's proceed to step 6:
6 divided by 5 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 87671.0
Subtracting 5 from 6 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
When dividing 10 by 5, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 87671.2
Subtract 10 from 10 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.

Moving on to step 8:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 87671.2
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:
When dividing 0 by 5, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 87671.2
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.

Our division results in 87671.2 with a remaining 0.0.
