We look at the division of 62910 by 75 
The aim is to understand the frequency of 75 in 62910.

Advancing to step 1:
If we divide 6 by 75, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 75

Let's proceed to step 2:
The number 75 fits into 62 0 times, leaving a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 62 after subtracting 0 from 62.
Fetch the next digit (9) from the dividend, attach it to 62 and continue: 629 / 75

Step 3:
75 goes into 629 8 times with a remainder of 29.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 600 from 629 to get 29.
Include the next digit (1) from the dividend after 29, then repeat: 291 / 75

Moving on to step 4:
The number 75 fits into 291 3 times, leaving a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 83.0
Subtracting 225 from 291 leaves us with 66.
Bring next digit (0) of the dividend behind the 66 and repeat the process: 660 / 75

Going ahead to step 5:
75 goes into 660 8 times with a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 838.0
If we subtract 600 from 660, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 6:
The number 75 fits into 600 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 838.8
If we subtract 600 from 600, 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.

Moving on to step 7:
The number 75 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 838.8
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.

On to step 8:
When dividing 0 by 75, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 838.8
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 838.8 with a remaining 0.0.
