We're dividing 899601 by 85 
The aim is to understand the frequency of 85 in 899601.

On to step 1:
8 divided by 85 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 85

Moving on to step 2:
85 goes into 89 1 times with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 85 from 89 leaves us with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 85

On to step 3:
If we divide 49 by 85, we get 0 and a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 49, we get 49.
Include the next digit (6) from the dividend after 49, then repeat: 496 / 85

Moving on to step 4:
496 divided by 85 is 5 with a remainder of 71.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
Subtracting 425 from 496 leaves us with 71.
Append the next digit (0) from the dividend to 71 and continue with: 710 / 85

Let's proceed to step 5:
The number 85 fits into 710 8 times, leaving a remainder of 30.
The next digit of our result is 8. 
Result so far: 1058.0
If we subtract 680 from 710, we get 30.
Bring next digit (1) of the dividend behind the 30 and repeat the process: 301 / 85

Step 6:
The number 85 fits into 301 3 times, leaving a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 10583.0
Deduct 255 from 301 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 7:
When dividing 460 by 85, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 10583.5
Subtract 425 from 460 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 8:
If we divide 350 by 85, we get 4 and a remainder of 10.
The next digit of our result is 4. 
Result so far: 10583.54
The remainder is 10 after subtracting 340 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
When dividing 100 by 85, we get 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 10583.541
Subtract 85 from 100 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
When dividing 150 by 85, we get 1 with a remainder of 65.
The next digit of our result is 1. 
Result so far: 10583.5411
The remainder is 65 after subtracting 85 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Our division results in 10583.5411 with a remaining 0.00065.
