We're dividing 523860 by 85 
The aim is to understand the frequency of 85 in 523860.

Advancing to step 1:
When dividing 5 by 85, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 85

Going ahead to step 2:
85 can be fit into 52 0 times, resulting in a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Fetch the next digit (3) from the dividend, attach it to 52 and continue: 523 / 85

Let's proceed to step 3:
The number 85 fits into 523 6 times, leaving a remainder of 13.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 510 from 523, we get 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 85

Let's proceed to step 4:
When dividing 138 by 85, we get 1 with a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 61.0
If we take 85 away from 138, we end up with 53.
Fetch the next digit (6) from the dividend, attach it to 53 and continue: 536 / 85

Going ahead to step 5:
85 goes into 536 6 times with a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 616.0
Subtracting 510 from 536 leaves us with 26.
Fetch the next digit (0) from the dividend, attach it to 26 and continue: 260 / 85

Advancing to step 6:
When dividing 260 by 85, we get 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 6163.0
Deduct 255 from 260 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
The number 85 fits into 50 0 times, leaving a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 6163.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
500 divided by 85 is 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 6163.05
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.

Step 9:
When dividing 750 by 85, we get 8 with a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 6163.058
Subtract 680 from 750 to 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 10:
85 can be fit into 700 8 times, resulting in a remainder of 20.
The next digit of our result is 8. 
Result so far: 6163.0588
If we take 680 away from 700, we end up 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 result is 6163.0588 with a remainder of 0.0002.
