71596 ÷ 75 
The aim is to understand the frequency of 75 in 71596.

Advancing to step 1:
75 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 75

Let's proceed to step 2:
The number 75 fits into 71 0 times, leaving a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Append the next digit (5) from the dividend to 71 and continue with: 715 / 75

Advancing to step 3:
75 can be fit into 715 9 times, resulting in a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 40 after subtracting 675 from 715.
Include the next digit (9) from the dividend after 40, then repeat: 409 / 75

Let's proceed to step 4:
75 can be fit into 409 5 times, resulting in a remainder of 34.
Use 5 as the next digit of our solution. 
Result so far: 95.0
Subtracting 375 from 409 leaves us with 34.
Include the next digit (6) from the dividend after 34, then repeat: 346 / 75

Going ahead to step 5:
The number 75 fits into 346 4 times, leaving a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 954.0
Deduct 300 from 346 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 6:
460 divided by 75 is 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 954.6
Deduct 450 from 460 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
75 can be fit into 100 1 times, resulting in a remainder of 25.
The next digit of our result is 1. 
Result so far: 954.61
Subtract 75 from 100 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 8:
The number 75 fits into 250 3 times, leaving a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 954.613
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.

On to step 9:
250 divided by 75 is 3 with a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 954.6133
Subtracting 225 from 250 leaves us 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.

The final result is 954.6133 with a remainder of 0.00025.
