We look at the division of 750210 by 5 
The aim is to understand the frequency of 5 in 750210.

Let's proceed to step 1:
7 divided by 5 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 5 away from 7, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 5

Moving on to step 2:
5 goes into 25 5 times 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.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 5

On to step 3:
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: 150.0
If we subtract 0 from 0, we get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 5

On to step 4:
When dividing 2 by 5, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 1500.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 5

Advancing to step 5:
5 can be fit into 21 4 times, resulting in a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 15004.0
Subtracting 20 from 21 leaves us with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 5

Going ahead to step 6:
If we divide 10 by 5, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 150042.0
Subtracting 10 from 10 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:
5 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 150042.0
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 8:
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: 150042.0
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.

After the division, we end up with 150042.0 and a remainder of 0.0.
