We're dividing 711687 by 85 
The aim is to understand the frequency of 85 in 711687.

Advancing to step 1:
The number 85 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 85

Step 2:
When dividing 71 by 85, we get 0 with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Include the next digit (1) from the dividend after 71, then repeat: 711 / 85

Advancing to step 3:
When dividing 711 by 85, we get 8 with a remainder of 31.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 31 after subtracting 680 from 711.
Grab the next digit (6) from the dividend, add it to 31, then carry on: 316 / 85

Moving on to step 4:
When dividing 316 by 85, we get 3 with a remainder of 61.
Write down 3 as next digit of the result. 
Result so far: 83.0
Subtracting 255 from 316 leaves us with 61.
Include the next digit (8) from the dividend after 61, then repeat: 618 / 85

Going ahead to step 5:
85 can be fit into 618 7 times, resulting in a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 837.0
Subtract 595 from 618 to get 23.
Bring next digit (7) of the dividend behind the 23 and repeat the process: 237 / 85

Going ahead to step 6:
The number 85 fits into 237 2 times, leaving a remainder of 67.
Put 2 as the next digit of the answer. 
Result so far: 8372.0
Subtracting 170 from 237 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 7:
If we divide 670 by 85, we get 7 and a remainder of 75.
Use 7 as the next digit of our solution. 
Result so far: 8372.7
Subtract 595 from 670 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 8:
85 goes into 750 8 times with a remainder of 70.
The next digit of our result is 8. 
Result so far: 8372.78
If we subtract 680 from 750, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 9:
85 can be fit into 700 8 times, resulting in a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 8372.788
Deduct 680 from 700 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 8372.788 with a remaining 0.002.
