Let's divide 353984 by 99
The aim is to understand the frequency of 99 in 353984.

Advancing to step 1:
99 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 99

Step 2:
The number 99 fits into 35 0 times, leaving a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Bring next digit (3) of the dividend behind the 35 and repeat the process: 353 / 99

Step 3:
The number 99 fits into 353 3 times, leaving a remainder of 56.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 297 from 353 and we're left with 56.
Bring next digit (9) of the dividend behind the 56 and repeat the process: 569 / 99

On to step 4:
The number 99 fits into 569 5 times, leaving a remainder of 74.
The next digit of our result is 5. 
Result so far: 35.0
Deduct 495 from 569 and we're left with 74.
Bring next digit (8) of the dividend behind the 74 and repeat the process: 748 / 99

Let's proceed to step 5:
When dividing 748 by 99, we get 7 with a remainder of 55.
Write down 7 as next digit of the result. 
Result so far: 357.0
The remainder is 55 after subtracting 693 from 748.
Take the next digit (4) from the dividend and append it to 55, then repeat: 554 / 99

Advancing to step 6:
If we divide 554 by 99, we get 5 and a remainder of 59.
Use 5 as the next digit of our solution. 
Result so far: 3575.0
Subtract 495 from 554 to 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.

On to step 7:
99 can be fit into 590 5 times, resulting in a remainder of 95.
Put 5 as the next digit of the answer. 
Result so far: 3575.5
Subtract 495 from 590 to 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.

Advancing to step 8:
99 can be fit into 950 9 times, resulting in a remainder of 59.
The next digit of our result is 9. 
Result so far: 3575.59
If we take 891 away from 950, we end up 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.

Step 9:
The number 99 fits into 590 5 times, leaving a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 3575.595
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.

Moving on to step 10:
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: 3575.5959
The remainder is 59 after subtracting 891 from 950.
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 11:
590 divided by 99 is 5 with a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 3575.59595
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 12:
99 goes into 950 9 times with a remainder of 59.
Record the quotient 9 as the next digit in the result. 
Result so far: 3575.595959
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 13:
99 can be fit into 590 5 times, resulting in a remainder of 95.
Write down 5 as next digit of the result. 
Result so far: 3575.5959595
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.

Let's proceed to step 14:
When dividing 950 by 99, we get 9 with a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 3575.59595959
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.

The quotient of the division is 3575.59595959, and the remainder is 5.9e-08.
