We look at the division of 189451 by 99 
The aim is to understand the frequency of 99 in 189451.

Step 1:
1 divided by 99 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 99

Step 2:
99 goes into 18 0 times with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 99

Advancing to step 3:
189 divided by 99 is 1 with a remainder of 90.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 99 from 189 and we're left with 90.
Bring next digit (4) of the dividend behind the 90 and repeat the process: 904 / 99

Moving on to step 4:
The number 99 fits into 904 9 times, leaving a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 891 from 904 and we're left with 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 99

Let's proceed to step 5:
135 divided by 99 is 1 with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 191.0
If we take 99 away from 135, we end up with 36.
Grab the next digit (1) from the dividend, add it to 36, then carry on: 361 / 99

Moving on to step 6:
The number 99 fits into 361 3 times, leaving a remainder of 64.
The next digit of our result is 3. 
Result so far: 1913.0
If we subtract 297 from 361, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 7:
99 goes into 640 6 times with a remainder of 46.
The next digit of our result is 6. 
Result so far: 1913.6
Subtract 594 from 640 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 8:
When dividing 460 by 99, we get 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 1913.64
If we take 396 away from 460, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 9:
99 goes into 640 6 times with a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 1913.646
Deduct 594 from 640 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
If we divide 460 by 99, we get 4 and a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 1913.6464
If we subtract 396 from 460, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 11:
640 divided by 99 is 6 with a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 1913.64646
If we subtract 594 from 640, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 12:
The number 99 fits into 460 4 times, leaving a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 1913.646464
Subtract 396 from 460 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 13:
When dividing 640 by 99, we get 6 with a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 1913.6464646
The remainder is 46 after subtracting 594 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 14:
99 can be fit into 460 4 times, resulting in a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 1913.64646464
If we subtract 396 from 460, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 1913.64646464 with a balance of 6.4e-08.
