182808 divided by 99 
The aim is to understand the frequency of 99 in 182808.

Step 1:
If we divide 1 by 99, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 99

On to step 2:
If we divide 18 by 99, we get 0 and a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 99

Going ahead to step 3:
99 can be fit into 182 1 times, resulting in a remainder of 83.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 99 from 182 leaves us with 83.
Include the next digit (8) from the dividend after 83, then repeat: 838 / 99

Step 4:
If we divide 838 by 99, we get 8 and a remainder of 46.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 792 from 838, we get 46.
Take the next digit (0) from the dividend and append it to 46, then repeat: 460 / 99

Moving on to step 5:
99 goes into 460 4 times with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 184.0
The remainder is 64 after subtracting 396 from 460.
Bring next digit (8) of the dividend behind the 64 and repeat the process: 648 / 99

Let's proceed to step 6:
99 goes into 648 6 times with a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 1846.0
Deduct 594 from 648 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 7:
If we divide 540 by 99, we get 5 and a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 1846.5
Deduct 495 from 540 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 8:
When dividing 450 by 99, we get 4 with a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 1846.54
Deduct 396 from 450 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 9:
540 divided by 99 is 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 1846.545
The remainder is 45 after subtracting 495 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 10:
99 can be fit into 450 4 times, resulting in a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 1846.5454
If we take 396 away from 450, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 11:
The number 99 fits into 540 5 times, leaving a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 1846.54545
Deduct 495 from 540 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 12:
450 divided by 99 is 4 with a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 1846.545454
If we subtract 396 from 450, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 13:
99 goes into 540 5 times with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 1846.5454545
If we take 495 away from 540, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 14:
The number 99 fits into 450 4 times, leaving a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 1846.54545454
If we take 396 away from 450, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 1846.54545454 and a remainder of 5.4e-08.
