Let's divide 317878 by 75
The aim is to understand the frequency of 75 in 317878.

Moving on to step 1:
The number 75 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 75

Let's proceed to step 2:
75 can be fit into 31 0 times, resulting in a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Fetch the next digit (7) from the dividend, attach it to 31 and continue: 317 / 75

Advancing to step 3:
317 divided by 75 is 4 with a remainder of 17.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 300 from 317 and we're left with 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 75

Step 4:
178 divided by 75 is 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtracting 150 from 178 leaves us with 28.
Grab the next digit (7) from the dividend, add it to 28, then carry on: 287 / 75

Advancing to step 5:
75 can be fit into 287 3 times, resulting in a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 423.0
Subtract 225 from 287 to get 62.
Append the next digit (8) from the dividend to 62 and continue with: 628 / 75

Going ahead to step 6:
The number 75 fits into 628 8 times, leaving a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 4238.0
The remainder is 28 after subtracting 600 from 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 7:
The number 75 fits into 280 3 times, leaving a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 4238.3
If we subtract 225 from 280, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 8:
550 divided by 75 is 7 with a remainder of 25.
The next digit of our result is 7. 
Result so far: 4238.37
Subtracting 525 from 550 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.

Moving on to step 9:
75 goes into 250 3 times with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 4238.373
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 10:
If we divide 250 by 75, we get 3 and a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 4238.3733
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.

After the division, we end up with 4238.3733 and a remainder of 0.00025.
