We're dividing 168415 by 75 
The aim is to understand the frequency of 75 in 168415.

Moving on to step 1:
When dividing 1 by 75, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 75

Let's proceed to step 2:
If we divide 16 by 75, we get 0 and a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 75

On to step 3:
168 divided by 75 is 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 18 after subtracting 150 from 168.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 75

Let's proceed to step 4:
When dividing 184 by 75, we get 2 with a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtract 150 from 184 to get 34.
Append the next digit (1) from the dividend to 34 and continue with: 341 / 75

Let's proceed to step 5:
When dividing 341 by 75, we get 4 with a remainder of 41.
Put 4 as the next digit of the answer. 
Result so far: 224.0
Deduct 300 from 341 and we're left with 41.
Append the next digit (5) from the dividend to 41 and continue with: 415 / 75

Going ahead to step 6:
The number 75 fits into 415 5 times, leaving a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 2245.0
If we take 375 away from 415, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
If we divide 400 by 75, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 2245.5
Subtract 375 from 400 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:
75 goes into 250 3 times with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 2245.53
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
75 goes into 250 3 times with a remainder of 25.
The next digit of our result is 3. 
Result so far: 2245.533
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 2245.533 and a remainder of 0.0025.
