We look at the division of 768619 by 75 
The aim is to understand the frequency of 75 in 768619.

Let's proceed to step 1:
If we divide 7 by 75, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 75

Going ahead to step 2:
76 divided by 75 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 75 from 76 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 75

On to step 3:
75 goes into 18 0 times with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 18 to get 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 75

Moving on to step 4:
When dividing 186 by 75, we get 2 with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 102.0
Deduct 150 from 186 and we're left with 36.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 75

Moving on to step 5:
When dividing 361 by 75, we get 4 with a remainder of 61.
The number 4 becomes the next digit in our result. 
Result so far: 1024.0
Subtract 300 from 361 to get 61.
Take the next digit (9) from the dividend and append it to 61, then repeat: 619 / 75

Advancing to step 6:
75 goes into 619 8 times with a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 10248.0
Deduct 600 from 619 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
When dividing 190 by 75, we get 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 10248.2
Subtracting 150 from 190 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
400 divided by 75 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 10248.25
The remainder is 25 after subtracting 375 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
If we divide 250 by 75, we get 3 and a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 10248.253
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 10:
250 divided by 75 is 3 with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 10248.2533
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

In conclusion, the division gives 10248.2533 with a balance of 0.00025.
