We're dividing 173956 by 75 
The aim is to understand the frequency of 75 in 173956.

On to step 1:
The number 75 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 75

Moving on to step 2:
If we divide 17 by 75, we get 0 and a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 75

Let's proceed to step 3:
75 can be fit into 173 2 times, resulting in a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 23 after subtracting 150 from 173.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 75

Step 4:
75 goes into 239 3 times with a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtracting 225 from 239 leaves us with 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 75

Advancing to step 5:
When dividing 145 by 75, we get 1 with a remainder of 70.
Use 1 as the next digit of our solution. 
Result so far: 231.0
If we subtract 75 from 145, we get 70.
Fetch the next digit (6) from the dividend, attach it to 70 and continue: 706 / 75

Step 6:
The number 75 fits into 706 9 times, leaving a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 2319.0
If we take 675 away from 706, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
75 goes into 310 4 times with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 2319.4
The remainder is 10 after subtracting 300 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
75 goes into 100 1 times with a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 2319.41
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.

Moving on to step 9:
75 can be fit into 250 3 times, resulting in a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 2319.413
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.

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: 2319.4133
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 2319.4133 with a remainder of 0.00025.
