We look at the division of 725134 by 99 
The aim is to understand the frequency of 99 in 725134.

Going ahead to step 1:
When dividing 7 by 99, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 99

On to step 2:
If we divide 72 by 99, we get 0 and a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Include the next digit (5) from the dividend after 72, then repeat: 725 / 99

Going ahead to step 3:
99 goes into 725 7 times with a remainder of 32.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 693 from 725, we get 32.
Take the next digit (1) from the dividend and append it to 32, then repeat: 321 / 99

On to step 4:
321 divided by 99 is 3 with a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 73.0
Subtracting 297 from 321 leaves us with 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 99

Let's proceed to step 5:
99 goes into 243 2 times with a remainder of 45.
Record the quotient 2 as the next digit in the result. 
Result so far: 732.0
If we subtract 198 from 243, we get 45.
Bring next digit (4) of the dividend behind the 45 and repeat the process: 454 / 99

Let's proceed to step 6:
If we divide 454 by 99, we get 4 and a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 7324.0
If we take 396 away from 454, 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.

Going ahead to step 7:
99 can be fit into 580 5 times, resulting in a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 7324.5
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.

Let's proceed to step 8:
If we divide 850 by 99, we get 8 and a remainder of 58.
The next digit of our result is 8. 
Result so far: 7324.58
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.

Step 9:
99 can be fit into 580 5 times, resulting in a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 7324.585
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.

Step 10:
850 divided by 99 is 8 with a remainder of 58.
The next digit of our result is 8. 
Result so far: 7324.5858
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.

On to step 11:
580 divided by 99 is 5 with a remainder of 85.
The next digit of our result is 5. 
Result so far: 7324.58585
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.

Step 12:
If we divide 850 by 99, we get 8 and a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 7324.585858
The remainder is 58 after subtracting 792 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 13:
If we divide 580 by 99, we get 5 and a remainder of 85.
The next digit of our result is 5. 
Result so far: 7324.5858585
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.

Advancing to step 14:
If we divide 850 by 99, we get 8 and a remainder of 58.
The next digit of our result is 8. 
Result so far: 7324.58585858
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.

In conclusion, the division gives 7324.58585858 with a balance of 5.8e-08.
