768535 divided by 85 
The aim is to understand the frequency of 85 in 768535.

Step 1:
85 goes into 7 0 times with 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.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 85

Let's proceed to step 2:
85 goes into 76 0 times with a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Grab the next digit (8) from the dividend, add it to 76, then carry on: 768 / 85

On to step 3:
768 divided by 85 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 765 from 768 to get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 85

Going ahead to step 4:
When dividing 35 by 85, we get 0 with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Subtracting 0 from 35 leaves us with 35.
Bring next digit (3) of the dividend behind the 35 and repeat the process: 353 / 85

Advancing to step 5:
85 goes into 353 4 times with a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 904.0
Subtract 340 from 353 to get 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 85

Step 6:
135 divided by 85 is 1 with a remainder of 50.
Use 1 as the next digit of our solution. 
Result so far: 9041.0
Subtracting 85 from 135 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 7:
85 goes into 500 5 times with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 9041.5
Deduct 425 from 500 and we're left 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.

Let's proceed to step 8:
85 can be fit into 750 8 times, resulting in a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 9041.58
Subtracting 680 from 750 leaves us with 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:
700 divided by 85 is 8 with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 9041.588
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.

The final outcome is 9041.588, with a leftover of 0.002.
