We divide 817949 by 99
The aim is to understand the frequency of 99 in 817949.

Going ahead to step 1:
When dividing 8 by 99, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 99

On to step 2:
If we divide 81 by 99, we get 0 and a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Bring next digit (7) of the dividend behind the 81 and repeat the process: 817 / 99

Moving on to step 3:
817 divided by 99 is 8 with a remainder of 25.
The next digit of our result is 8. 
Result so far: 8.0
If we take 792 away from 817, we end up with 25.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 99

Moving on to step 4:
If we divide 259 by 99, we get 2 and a remainder of 61.
Put 2 as the next digit of the answer. 
Result so far: 82.0
Subtracting 198 from 259 leaves us with 61.
Bring next digit (4) of the dividend behind the 61 and repeat the process: 614 / 99

Advancing to step 5:
If we divide 614 by 99, we get 6 and a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 826.0
Deduct 594 from 614 and we're left with 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 99

Advancing to step 6:
The number 99 fits into 209 2 times, leaving a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 8262.0
If we take 198 away from 209, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
99 goes into 110 1 times with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 8262.1
The remainder is 11 after subtracting 99 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 8:
99 can be fit into 110 1 times, resulting in a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 8262.11
If we take 99 away from 110, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 8262.11, with a leftover of 0.011.
