We're dividing 28515 by 74 
The aim is to understand the frequency of 74 in 28515.

Advancing to step 1:
The number 74 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 74

Moving on to step 2:
If we divide 28 by 74, we get 0 and a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 74

Let's proceed to step 3:
74 goes into 285 3 times with a remainder of 63.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 222 away from 285, we end up with 63.
Take the next digit (1) from the dividend and append it to 63, then repeat: 631 / 74

Moving on to step 4:
When dividing 631 by 74, we get 8 with a remainder of 39.
Write down 8 as next digit of the result. 
Result so far: 38.0
If we subtract 592 from 631, we get 39.
Fetch the next digit (5) from the dividend, attach it to 39 and continue: 395 / 74

Let's proceed to step 5:
The number 74 fits into 395 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 385.0
Subtract 370 from 395 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.

On to step 6:
74 goes into 250 3 times with a remainder of 28.
The next digit of our result is 3. 
Result so far: 385.3
The remainder is 28 after subtracting 222 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 7:
280 divided by 74 is 3 with a remainder of 58.
The number 3 becomes the next digit in our result. 
Result so far: 385.33
The remainder is 58 after subtracting 222 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

After the division, we end up with 385.33 and a remainder of 0.058.
