We're dividing 342175 by 85 
The aim is to understand the frequency of 85 in 342175.

Advancing to step 1:
The number 85 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 85

Advancing to step 2:
85 can be fit into 34 0 times, resulting in a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 85

Moving on to step 3:
The number 85 fits into 342 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 340 from 342 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 85

Step 4:
85 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Deduct 0 from 21 and we're left with 21.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 85

Step 5:
217 divided by 85 is 2 with a remainder of 47.
Record the quotient 2 as the next digit in the result. 
Result so far: 402.0
The remainder is 47 after subtracting 170 from 217.
Bring next digit (5) of the dividend behind the 47 and repeat the process: 475 / 85

Let's proceed to step 6:
475 divided by 85 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 4025.0
The remainder is 50 after subtracting 425 from 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 7:
85 goes into 500 5 times with a remainder of 75.
The next digit of our result is 5. 
Result so far: 4025.5
Subtracting 425 from 500 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 8:
The number 85 fits into 750 8 times, leaving a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 4025.58
The remainder is 70 after subtracting 680 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 9:
700 divided by 85 is 8 with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 4025.588
Subtract 680 from 700 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 4025.588 and a remainder of 0.002.
