We look at the division of 491726 by 99 
The aim is to understand the frequency of 99 in 491726.

On to step 1:
When dividing 4 by 99, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 99

Going ahead to step 2:
When dividing 49 by 99, we get 0 with a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Grab the next digit (1) from the dividend, add it to 49, then carry on: 491 / 99

Moving on to step 3:
If we divide 491 by 99, we get 4 and a remainder of 95.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 396 from 491, we get 95.
Take the next digit (7) from the dividend and append it to 95, then repeat: 957 / 99

Going ahead to step 4:
99 can be fit into 957 9 times, resulting in a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Deduct 891 from 957 and we're left with 66.
Take the next digit (2) from the dividend and append it to 66, then repeat: 662 / 99

Moving on to step 5:
The number 99 fits into 662 6 times, leaving a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 496.0
The remainder is 68 after subtracting 594 from 662.
Take the next digit (6) from the dividend and append it to 68, then repeat: 686 / 99

Moving on to step 6:
If we divide 686 by 99, we get 6 and a remainder of 92.
Write down 6 as next digit of the result. 
Result so far: 4966.0
Deduct 594 from 686 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 7:
When dividing 920 by 99, we get 9 with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 4966.9
The remainder is 29 after subtracting 891 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 8:
99 goes into 290 2 times with a remainder of 92.
The number 2 becomes the next digit in our result. 
Result so far: 4966.92
Subtracting 198 from 290 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 9:
99 goes into 920 9 times with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 4966.929
Subtract 891 from 920 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 10:
99 goes into 290 2 times with a remainder of 92.
The next digit of our result is 2. 
Result so far: 4966.9292
If we subtract 198 from 290, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 11:
920 divided by 99 is 9 with a remainder of 29.
The next digit of our result is 9. 
Result so far: 4966.92929
The remainder is 29 after subtracting 891 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 12:
99 goes into 290 2 times with a remainder of 92.
The number 2 becomes the next digit in our result. 
Result so far: 4966.929292
If we subtract 198 from 290, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 13:
If we divide 920 by 99, we get 9 and a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 4966.9292929
Deduct 891 from 920 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 14:
The number 99 fits into 290 2 times, leaving a remainder of 92.
The number 2 becomes the next digit in our result. 
Result so far: 4966.92929292
Subtracting 198 from 290 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.
