We look at the division of 84865 by 99 
The aim is to understand the frequency of 99 in 84865.

Step 1:
When dividing 8 by 99, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 99

Advancing to step 2:
The number 99 fits into 84 0 times, leaving a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Append the next digit (8) from the dividend to 84 and continue with: 848 / 99

Step 3:
When dividing 848 by 99, we get 8 with a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 792 away from 848, we end up with 56.
Fetch the next digit (6) from the dividend, attach it to 56 and continue: 566 / 99

Step 4:
99 can be fit into 566 5 times, resulting in a remainder of 71.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
Subtract 495 from 566 to get 71.
Fetch the next digit (5) from the dividend, attach it to 71 and continue: 715 / 99

Step 5:
99 can be fit into 715 7 times, resulting in a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 857.0
If we subtract 693 from 715, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 6:
99 goes into 220 2 times with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 857.2
The remainder is 22 after subtracting 198 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 7:
When dividing 220 by 99, we get 2 with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 857.22
Deduct 198 from 220 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 857.22, with a leftover of 0.022.
