We divide 825619 by 99
The aim is to understand the frequency of 99 in 825619.

Moving on to step 1:
If we divide 8 by 99, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 99

On to step 2:
82 divided by 99 is 0 with a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 82 after subtracting 0 from 82.
Take the next digit (5) from the dividend and append it to 82, then repeat: 825 / 99

Advancing to step 3:
The number 99 fits into 825 8 times, leaving a remainder of 33.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 792 away from 825, we end up with 33.
Append the next digit (6) from the dividend to 33 and continue with: 336 / 99

Moving on to step 4:
99 can be fit into 336 3 times, resulting in a remainder of 39.
The next digit of our result is 3. 
Result so far: 83.0
The remainder is 39 after subtracting 297 from 336.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 99

Step 5:
391 divided by 99 is 3 with a remainder of 94.
Use 3 as the next digit of our solution. 
Result so far: 833.0
Subtracting 297 from 391 leaves us with 94.
Bring next digit (9) of the dividend behind the 94 and repeat the process: 949 / 99

Step 6:
When dividing 949 by 99, we get 9 with a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 8339.0
If we take 891 away from 949, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 7:
If we divide 580 by 99, we get 5 and a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 8339.5
If we take 495 away from 580, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 8:
99 goes into 850 8 times with a remainder of 58.
The next digit of our result is 8. 
Result so far: 8339.58
Subtract 792 from 850 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 9:
99 can be fit into 580 5 times, resulting in a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 8339.585
The remainder is 85 after subtracting 495 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 10:
The number 99 fits into 850 8 times, leaving a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 8339.5858
Subtract 792 from 850 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 11:
The number 99 fits into 580 5 times, leaving a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 8339.58585
Subtracting 495 from 580 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 12:
99 can be fit into 850 8 times, resulting in a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 8339.585858
Deduct 792 from 850 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 13:
If we divide 580 by 99, we get 5 and a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 8339.5858585
If we subtract 495 from 580, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 14:
The number 99 fits into 850 8 times, leaving a remainder of 58.
The next digit of our result is 8. 
Result so far: 8339.58585858
Subtracting 792 from 850 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final outcome is 8339.58585858, with a leftover of 5.8e-08.
