We look at the division of 115353 by 75 
The aim is to understand the frequency of 75 in 115353.

On to step 1:
75 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 75

Advancing to step 2:
When dividing 11 by 75, we get 0 with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 75

Advancing to step 3:
The number 75 fits into 115 1 times, leaving a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 75 away from 115, we end up with 40.
Bring next digit (3) of the dividend behind the 40 and repeat the process: 403 / 75

Step 4:
The number 75 fits into 403 5 times, leaving a remainder of 28.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 28 after subtracting 375 from 403.
Bring next digit (5) of the dividend behind the 28 and repeat the process: 285 / 75

Moving on to step 5:
285 divided by 75 is 3 with a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 153.0
Deduct 225 from 285 and we're left with 60.
Append the next digit (3) from the dividend to 60 and continue with: 603 / 75

Advancing to step 6:
75 can be fit into 603 8 times, resulting in a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 1538.0
Subtract 600 from 603 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
When dividing 30 by 75, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 1538.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
When dividing 300 by 75, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 1538.04
Deduct 300 from 300 and we're left 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.

On to step 9:
75 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1538.04
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 10:
75 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 1538.04
Subtract 0 from 0 to 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.

After the division, we end up with 1538.04 and a remainder of 0.0.
