173950 ÷ 75 
The aim is to understand the frequency of 75 in 173950.

Let's proceed 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 (7) from the dividend, add it to 1, then carry on: 17 / 75

Going ahead to step 2:
75 goes into 17 0 times with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 75

Moving on to step 3:
75 can be fit into 173 2 times, resulting in a remainder of 23.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 150 from 173 to get 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 75

On to step 4:
If we divide 239 by 75, we get 3 and a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Subtracting 225 from 239 leaves us with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 75

Let's proceed to step 5:
When dividing 145 by 75, we get 1 with a remainder of 70.
Record the quotient 1 as the next digit in the result. 
Result so far: 231.0
If we take 75 away from 145, we end up with 70.
Append the next digit (0) from the dividend to 70 and continue with: 700 / 75

Going ahead to step 6:
75 goes into 700 9 times with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 2319.0
Subtracting 675 from 700 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.

Advancing to step 7:
75 goes into 250 3 times with a remainder of 25.
The next digit of our result is 3. 
Result so far: 2319.3
If we take 225 away from 250, 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.

On to step 8:
When dividing 250 by 75, we get 3 with a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 2319.33
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 2319.33 with a remaining 0.025.
