We look at the division of 941572 by 75 
The aim is to understand the frequency of 75 in 941572.

Step 1:
The number 75 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 75

Advancing to step 2:
When dividing 94 by 75, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 75 from 94, we get 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 75

Step 3:
The number 75 fits into 191 2 times, leaving a remainder of 41.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 150 from 191 and we're left with 41.
Grab the next digit (5) from the dividend, add it to 41, then carry on: 415 / 75

Step 4:
If we divide 415 by 75, we get 5 and a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 125.0
Subtracting 375 from 415 leaves us with 40.
Include the next digit (7) from the dividend after 40, then repeat: 407 / 75

Going ahead to step 5:
When dividing 407 by 75, we get 5 with a remainder of 32.
The number 5 becomes the next digit in our result. 
Result so far: 1255.0
If we take 375 away from 407, we end up with 32.
Bring next digit (2) of the dividend behind the 32 and repeat the process: 322 / 75

Let's proceed to step 6:
If we divide 322 by 75, we get 4 and a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 12554.0
If we subtract 300 from 322, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
75 goes into 220 2 times with a remainder of 70.
Write down 2 as next digit of the result. 
Result so far: 12554.2
The remainder is 70 after subtracting 150 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
75 goes into 700 9 times with a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 12554.29
Deduct 675 from 700 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 9:
75 can be fit into 250 3 times, resulting in a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 12554.293
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.

Advancing to step 10:
The number 75 fits into 250 3 times, leaving a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 12554.2933
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.

Our division results in 12554.2933 with a remaining 0.00025.
