We look at the division of 617360 by 85 
The aim is to understand the frequency of 85 in 617360.

Let's proceed to step 1:
6 divided by 85 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 85

Let's proceed to step 2:
If we divide 61 by 85, we get 0 and a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Append the next digit (7) from the dividend to 61 and continue with: 617 / 85

Going ahead to step 3:
When dividing 617 by 85, we get 7 with a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 595 away from 617, we end up with 22.
Take the next digit (3) from the dividend and append it to 22, then repeat: 223 / 85

Advancing to step 4:
85 goes into 223 2 times with a remainder of 53.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
If we subtract 170 from 223, we get 53.
Fetch the next digit (6) from the dividend, attach it to 53 and continue: 536 / 85

Going ahead to step 5:
536 divided by 85 is 6 with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 726.0
Deduct 510 from 536 and we're left with 26.
Fetch the next digit (0) from the dividend, attach it to 26 and continue: 260 / 85

Step 6:
260 divided by 85 is 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 7263.0
Subtracting 255 from 260 leaves us 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.

Going ahead to step 7:
85 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 7263.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
85 goes into 500 5 times with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 7263.05
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.

Going ahead to step 9:
The number 85 fits into 750 8 times, leaving a remainder of 70.
The next digit of our result is 8. 
Result so far: 7263.058
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.

Advancing to step 10:
85 can be fit into 700 8 times, resulting in a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 7263.0588
The remainder is 20 after subtracting 680 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 7263.0588 and a remainder of 0.0002.
