We look at the division of 864477 by 75 
The aim is to understand the frequency of 75 in 864477.

Let's proceed to step 1:
8 divided by 75 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 75

On to step 2:
When dividing 86 by 75, we get 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 11 after subtracting 75 from 86.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 75

Step 3:
When dividing 114 by 75, we get 1 with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 75 from 114 leaves us with 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 75

Step 4:
When dividing 394 by 75, we get 5 with a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 115.0
Subtract 375 from 394 to get 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 75

Step 5:
The number 75 fits into 197 2 times, leaving a remainder of 47.
Put 2 as the next digit of the answer. 
Result so far: 1152.0
Subtract 150 from 197 to get 47.
Append the next digit (7) from the dividend to 47 and continue with: 477 / 75

Moving on to step 6:
If we divide 477 by 75, we get 6 and a remainder of 27.
The number 6 becomes the next digit in our result. 
Result so far: 11526.0
Deduct 450 from 477 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
When dividing 270 by 75, we get 3 with a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 11526.3
Subtracting 225 from 270 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 8:
75 can be fit into 450 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 11526.36
If we take 450 away from 450, 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.

Going ahead to step 9:
If we divide 0 by 75, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11526.36
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.

Advancing to step 10:
When dividing 0 by 75, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11526.36
If we take 0 away from 0, 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.

After the division, we end up with 11526.36 and a remainder of 0.0.
