We're dividing 335496 by 99 
The aim is to understand the frequency of 99 in 335496.

Going ahead to step 1:
When dividing 3 by 99, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 99

Advancing to step 2:
The number 99 fits into 33 0 times, leaving a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 33 and we're left with 33.
Include the next digit (5) from the dividend after 33, then repeat: 335 / 99

Let's proceed to step 3:
When dividing 335 by 99, we get 3 with a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 297 away from 335, we end up with 38.
Include the next digit (4) from the dividend after 38, then repeat: 384 / 99

Going ahead to step 4:
384 divided by 99 is 3 with a remainder of 87.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
If we take 297 away from 384, we end up with 87.
Include the next digit (9) from the dividend after 87, then repeat: 879 / 99

Let's proceed to step 5:
879 divided by 99 is 8 with a remainder of 87.
Put 8 as the next digit of the answer. 
Result so far: 338.0
Deduct 792 from 879 and we're left with 87.
Bring next digit (6) of the dividend behind the 87 and repeat the process: 876 / 99

Step 6:
99 goes into 876 8 times with a remainder of 84.
Use 8 as the next digit of our solution. 
Result so far: 3388.0
Subtracting 792 from 876 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 7:
840 divided by 99 is 8 with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 3388.8
The remainder is 48 after subtracting 792 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 8:
480 divided by 99 is 4 with a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 3388.84
If we subtract 396 from 480, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 9:
The number 99 fits into 840 8 times, leaving a remainder of 48.
The next digit of our result is 8. 
Result so far: 3388.848
Deduct 792 from 840 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
The number 99 fits into 480 4 times, leaving a remainder of 84.
Use 4 as the next digit of our solution. 
Result so far: 3388.8484
Subtracting 396 from 480 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 11:
If we divide 840 by 99, we get 8 and a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 3388.84848
Deduct 792 from 840 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 12:
When dividing 480 by 99, we get 4 with a remainder of 84.
Write down 4 as next digit of the result. 
Result so far: 3388.848484
Subtracting 396 from 480 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 13:
The number 99 fits into 840 8 times, leaving a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 3388.8484848
If we subtract 792 from 840, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 14:
If we divide 480 by 99, we get 4 and a remainder of 84.
Use 4 as the next digit of our solution. 
Result so far: 3388.84848484
Subtracting 396 from 480 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Our division results in 3388.84848484 with a remaining 8.4e-08.
