We look at the division of 75134625 by 5 
The aim is to understand the frequency of 5 in 75134625.

Moving on to step 1:
If we divide 7 by 5, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 5 from 7 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 5

Going ahead to step 2:
25 divided by 5 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 15.0
If we take 25 away from 25, we end up with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 5

Step 3:
1 divided by 5 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 150.0
Subtract 0 from 1 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 5

Moving on to step 4:
5 goes into 13 2 times with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 1502.0
The remainder is 3 after subtracting 10 from 13.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 5

Moving on to step 5:
The number 5 fits into 34 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 15026.0
If we take 30 away from 34, we end up with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 5

Let's proceed to step 6:
5 goes into 46 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 150269.0
Deduct 45 from 46 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 5

On to step 7:
If we divide 12 by 5, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 1502692.0
Subtract 10 from 12 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 5

On to step 8:
25 divided by 5 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 15026925.0
Subtracting 25 from 25 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.

On to step 9:
5 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15026925.0
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.

Let's proceed to step 10:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15026925.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 15026925.0 with a remainder of 0.0.
