We look at the division of 495984 by 85 
The aim is to understand the frequency of 85 in 495984.

Step 1:
85 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 85

Going ahead to step 2:
49 divided by 85 is 0 with a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 49 to get 49.
Append the next digit (5) from the dividend to 49 and continue with: 495 / 85

Moving on to step 3:
The number 85 fits into 495 5 times, leaving a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 425 from 495, we get 70.
Take the next digit (9) from the dividend and append it to 70, then repeat: 709 / 85

Step 4:
85 can be fit into 709 8 times, resulting in a remainder of 29.
Write down 8 as next digit of the result. 
Result so far: 58.0
Subtract 680 from 709 to get 29.
Grab the next digit (8) from the dividend, add it to 29, then carry on: 298 / 85

On to step 5:
85 can be fit into 298 3 times, resulting in a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 583.0
Subtract 255 from 298 to get 43.
Append the next digit (4) from the dividend to 43 and continue with: 434 / 85

Let's proceed to step 6:
434 divided by 85 is 5 with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 5835.0
If we subtract 425 from 434, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
85 can be fit into 90 1 times, resulting in a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 5835.1
The remainder is 5 after subtracting 85 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
When dividing 50 by 85, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 5835.1
Subtracting 0 from 50 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.

Let's proceed to step 9:
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: 5835.105
Subtract 425 from 500 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.

Advancing to step 10:
The number 85 fits into 750 8 times, leaving a remainder of 70.
The next digit of our result is 8. 
Result so far: 5835.1058
The remainder is 70 after subtracting 680 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 11:
If we divide 700 by 85, we get 8 and a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 5835.10588
Subtract 680 from 700 to get 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 5835.10588 with a remaining 2e-05.
