We divide 307920 by 5
The aim is to understand the frequency of 5 in 307920.

Step 1:
The number 5 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 5

Step 2:
30 divided by 5 is 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 30 away from 30, we end up with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 5

On to step 3:
5 goes into 7 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 61.0
If we take 5 away from 7, we end up with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 5

Step 4:
29 divided by 5 is 5 with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 615.0
If we take 25 away from 29, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 5

Going ahead to step 5:
If we divide 42 by 5, we get 8 and a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 6158.0
If we take 40 away from 42, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 5

Advancing to step 6:
The number 5 fits into 20 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 61584.0
If we take 20 away from 20, we end up 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 7:
0 divided by 5 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 61584.0
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.

On to step 8:
The number 5 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 61584.0
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.

Our division results in 61584.0 with a remaining 0.0.
