30749 divided by 99 
The aim is to understand the frequency of 99 in 30749.

Let's proceed to step 1:
When dividing 3 by 99, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 99

On to step 2:
99 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 99

Step 3:
307 divided by 99 is 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 297 from 307 to get 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 99

Step 4:
When dividing 104 by 99, we get 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 31.0
Deduct 99 from 104 and we're left with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 99

Let's proceed to step 5:
99 goes into 59 0 times with a remainder of 59.
Record the quotient 0 as the next digit in the result. 
Result so far: 310.0
If we take 0 away from 59, 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.

Advancing to step 6:
If we divide 590 by 99, we get 5 and a remainder of 95.
Use 5 as the next digit of our solution. 
Result so far: 310.5
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 7:
The number 99 fits into 950 9 times, leaving a remainder of 59.
Use 9 as the next digit of our solution. 
Result so far: 310.59
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.

Let's proceed to step 8:
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: 310.595
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.

Step 9:
99 goes into 950 9 times with a remainder of 59.
Use 9 as the next digit of our solution. 
Result so far: 310.5959
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.

Step 10:
99 can be fit into 590 5 times, resulting in a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 310.59595
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.

On to step 11:
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: 310.595959
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.

Advancing to step 12:
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: 310.5959595
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.

Moving on to step 13:
99 goes into 950 9 times with a remainder of 59.
Use 9 as the next digit of our solution. 
Result so far: 310.59595959
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.

Our division results in 310.59595959 with a remaining 5.9e-08.
