93558 ÷ 99 
The aim is to understand the frequency of 99 in 93558.

Step 1:
When dividing 9 by 99, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 99

On to step 2:
99 goes into 93 0 times with a remainder of 93.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 93 after subtracting 0 from 93.
Bring next digit (5) of the dividend behind the 93 and repeat the process: 935 / 99

Step 3:
When dividing 935 by 99, we get 9 with a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 891 from 935 and we're left with 44.
Bring next digit (5) of the dividend behind the 44 and repeat the process: 445 / 99

On to step 4:
If we divide 445 by 99, we get 4 and a remainder of 49.
Write down 4 as next digit of the result. 
Result so far: 94.0
If we take 396 away from 445, we end up with 49.
Take the next digit (8) from the dividend and append it to 49, then repeat: 498 / 99

Going ahead to step 5:
When dividing 498 by 99, we get 5 with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 945.0
Subtract 495 from 498 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 6:
If we divide 30 by 99, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 945.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
300 divided by 99 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 945.03
The remainder is 3 after subtracting 297 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 8:
99 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 945.03
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
99 can be fit into 300 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 945.0303
Subtract 297 from 300 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
99 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 945.0303
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
99 can be fit into 300 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 945.030303
Subtracting 297 from 300 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 12:
99 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 945.030303
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
99 goes into 300 3 times with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 945.03030303
If we take 297 away from 300, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 945.03030303 and a remainder of 3e-09.
