We look at the division of 310351 by 99 
The aim is to understand the frequency of 99 in 310351.

Advancing to step 1:
99 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 99

Let's proceed to step 2:
The number 99 fits into 31 0 times, leaving a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Include the next digit (0) from the dividend after 31, then repeat: 310 / 99

Let's proceed to step 3:
If we divide 310 by 99, we get 3 and a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 13 after subtracting 297 from 310.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 99

On to step 4:
When dividing 133 by 99, we get 1 with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we subtract 99 from 133, we get 34.
Bring next digit (5) of the dividend behind the 34 and repeat the process: 345 / 99

Let's proceed to step 5:
345 divided by 99 is 3 with a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 313.0
The remainder is 48 after subtracting 297 from 345.
Fetch the next digit (1) from the dividend, attach it to 48 and continue: 481 / 99

On to step 6:
When dividing 481 by 99, we get 4 with a remainder of 85.
The next digit of our result is 4. 
Result so far: 3134.0
If we take 396 away from 481, 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 7:
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: 3134.8
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 8:
580 divided by 99 is 5 with a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 3134.85
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.

Let's proceed to step 9:
99 goes into 850 8 times with a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 3134.858
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.

On to step 10:
When dividing 580 by 99, we get 5 with a remainder of 85.
The next digit of our result is 5. 
Result so far: 3134.8585
Subtract 495 from 580 to 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.

Advancing to step 11:
When dividing 850 by 99, we get 8 with a remainder of 58.
The next digit of our result is 8. 
Result so far: 3134.85858
If we subtract 792 from 850, we 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 12:
99 goes into 580 5 times with a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 3134.858585
Deduct 495 from 580 and we're left 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 13:
850 divided by 99 is 8 with a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 3134.8585858
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 14:
99 goes into 580 5 times with a remainder of 85.
The next digit of our result is 5. 
Result so far: 3134.85858585
Subtract 495 from 580 to 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.

In conclusion, the division gives 3134.85858585 with a balance of 8.5e-08.
