We look at the division of 327438 by 85 
The aim is to understand the frequency of 85 in 327438.

On to step 1:
85 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 85

Moving on to step 2:
85 goes into 32 0 times with a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 32, we get 32.
Grab the next digit (7) from the dividend, add it to 32, then carry on: 327 / 85

Going ahead to step 3:
The number 85 fits into 327 3 times, leaving a remainder of 72.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 72 after subtracting 255 from 327.
Take the next digit (4) from the dividend and append it to 72, then repeat: 724 / 85

Advancing to step 4:
85 can be fit into 724 8 times, resulting in a remainder of 44.
The next digit of our result is 8. 
Result so far: 38.0
If we take 680 away from 724, we end up with 44.
Grab the next digit (3) from the dividend, add it to 44, then carry on: 443 / 85

Moving on to step 5:
85 goes into 443 5 times with a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 385.0
If we subtract 425 from 443, we get 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 85

Let's proceed to step 6:
The number 85 fits into 188 2 times, leaving a remainder of 18.
The next digit of our result is 2. 
Result so far: 3852.0
Subtracting 170 from 188 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
85 can be fit into 180 2 times, resulting in a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 3852.2
The remainder is 10 after subtracting 170 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
If we divide 100 by 85, we get 1 and a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 3852.21
Subtract 85 from 100 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
When dividing 150 by 85, we get 1 with a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 3852.211
Deduct 85 from 150 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

After the division, we end up with 3852.211 and a remainder of 0.0065.
