We're dividing 16950 by 85 
The aim is to understand the frequency of 85 in 16950.

Step 1:
85 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 85

Moving on to step 2:
85 goes into 16 0 times with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 85

Let's proceed to step 3:
85 goes into 169 1 times with a remainder of 84.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 84 after subtracting 85 from 169.
Bring next digit (5) of the dividend behind the 84 and repeat the process: 845 / 85

Moving on to step 4:
85 can be fit into 845 9 times, resulting in a remainder of 80.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 765 from 845 and we're left with 80.
Grab the next digit (0) from the dividend, add it to 80, then carry on: 800 / 85

On to step 5:
The number 85 fits into 800 9 times, leaving a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 199.0
The remainder is 35 after subtracting 765 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 6:
85 goes into 350 4 times with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 199.4
If we subtract 340 from 350, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
100 divided by 85 is 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 199.41
The remainder is 15 after subtracting 85 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
85 goes into 150 1 times with a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 199.411
If we take 85 away from 150, we end up 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.

The final result is 199.411 with a remainder of 0.0065.
