We look at the division of 532585 by 75 
The aim is to understand the frequency of 75 in 532585.

Step 1:
When dividing 5 by 75, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 75

Moving on to step 2:
If we divide 53 by 75, we get 0 and a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Bring next digit (2) of the dividend behind the 53 and repeat the process: 532 / 75

Going ahead to step 3:
532 divided by 75 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 525 away from 532, we end up with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 75

On to step 4:
75 can be fit into 75 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 71.0
Deduct 75 from 75 and we're left with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 75

Going ahead to step 5:
75 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 710.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 75

Step 6:
85 divided by 75 is 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 7101.0
The remainder is 10 after subtracting 75 from 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
When dividing 100 by 75, we get 1 with a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 7101.1
If we take 75 away from 100, 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.

Let's proceed to step 8:
250 divided by 75 is 3 with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 7101.13
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
250 divided by 75 is 3 with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 7101.133
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.

Our division results in 7101.133 with a remaining 0.0025.
