We divide 828553 by 99
The aim is to understand the frequency of 99 in 828553.

Moving on to step 1:
8 divided by 99 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 99

Going ahead to step 2:
99 can be fit into 82 0 times, resulting in a remainder of 82.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 82 to get 82.
Bring next digit (8) of the dividend behind the 82 and repeat the process: 828 / 99

On to step 3:
When dividing 828 by 99, we get 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 36 after subtracting 792 from 828.
Append the next digit (5) from the dividend to 36 and continue with: 365 / 99

On to step 4:
When dividing 365 by 99, we get 3 with a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 83.0
The remainder is 68 after subtracting 297 from 365.
Bring next digit (5) of the dividend behind the 68 and repeat the process: 685 / 99

Let's proceed to step 5:
The number 99 fits into 685 6 times, leaving a remainder of 91.
Use 6 as the next digit of our solution. 
Result so far: 836.0
Subtract 594 from 685 to get 91.
Grab the next digit (3) from the dividend, add it to 91, then carry on: 913 / 99

Going ahead to step 6:
The number 99 fits into 913 9 times, leaving a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 8369.0
If we take 891 away from 913, we end up 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.

Going ahead to step 7:
If we divide 220 by 99, we get 2 and a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 8369.2
If we take 198 away from 220, we end up 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.

On to step 8:
99 goes into 220 2 times with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 8369.22
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.

The final outcome is 8369.22, with a leftover of 0.022.
