We look at the division of 125294 by 99 
The aim is to understand the frequency of 99 in 125294.

Moving on to step 1:
99 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 99

Step 2:
When dividing 12 by 99, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 99

Step 3:
The number 99 fits into 125 1 times, leaving a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 99 from 125 and we're left with 26.
Include the next digit (2) from the dividend after 26, then repeat: 262 / 99

Advancing to step 4:
The number 99 fits into 262 2 times, leaving a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 198 from 262 to get 64.
Grab the next digit (9) from the dividend, add it to 64, then carry on: 649 / 99

On to step 5:
99 goes into 649 6 times with a remainder of 55.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
If we take 594 away from 649, we end up with 55.
Append the next digit (4) from the dividend to 55 and continue with: 554 / 99

Step 6:
99 can be fit into 554 5 times, resulting in a remainder of 59.
The number 5 becomes the next digit in our result. 
Result so far: 1265.0
If we subtract 495 from 554, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 7:
If we divide 590 by 99, we get 5 and a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 1265.5
If we subtract 495 from 590, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 8:
If we divide 950 by 99, we get 9 and a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 1265.59
Deduct 891 from 950 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 9:
If we divide 590 by 99, we get 5 and a remainder of 95.
Write down 5 as next digit of the result. 
Result so far: 1265.595
The remainder is 95 after subtracting 495 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 10:
The number 99 fits into 950 9 times, leaving a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 1265.5959
Subtracting 891 from 950 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 11:
590 divided by 99 is 5 with a remainder of 95.
The next digit of our result is 5. 
Result so far: 1265.59595
Subtracting 495 from 590 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 12:
99 can be fit into 950 9 times, resulting in a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 1265.595959
If we subtract 891 from 950, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 13:
The number 99 fits into 590 5 times, leaving a remainder of 95.
Write down 5 as next digit of the result. 
Result so far: 1265.5959595
Deduct 495 from 590 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 14:
The number 99 fits into 950 9 times, leaving a remainder of 59.
The next digit of our result is 9. 
Result so far: 1265.59595959
Subtracting 891 from 950 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

The final outcome is 1265.59595959, with a leftover of 5.9e-08.
