363181 ÷ 99 
The aim is to understand the frequency of 99 in 363181.

Going ahead to step 1:
3 divided by 99 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 99

Step 2:
36 divided by 99 is 0 with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 36 leaves us with 36.
Bring next digit (3) of the dividend behind the 36 and repeat the process: 363 / 99

Let's proceed to step 3:
99 goes into 363 3 times with a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 297 from 363 and we're left with 66.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 99

Advancing to step 4:
99 can be fit into 661 6 times, resulting in a remainder of 67.
The next digit of our result is 6. 
Result so far: 36.0
Subtracting 594 from 661 leaves us with 67.
Take the next digit (8) from the dividend and append it to 67, then repeat: 678 / 99

On to step 5:
If we divide 678 by 99, we get 6 and a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 366.0
Subtracting 594 from 678 leaves us with 84.
Grab the next digit (1) from the dividend, add it to 84, then carry on: 841 / 99

Moving on to step 6:
The number 99 fits into 841 8 times, leaving a remainder of 49.
The number 8 becomes the next digit in our result. 
Result so far: 3668.0
Subtract 792 from 841 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
If we divide 490 by 99, we get 4 and a remainder of 94.
The next digit of our result is 4. 
Result so far: 3668.4
If we take 396 away from 490, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 8:
940 divided by 99 is 9 with a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 3668.49
Deduct 891 from 940 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 9:
When dividing 490 by 99, we get 4 with a remainder of 94.
The number 4 becomes the next digit in our result. 
Result so far: 3668.494
If we take 396 away from 490, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 10:
99 goes into 940 9 times with a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 3668.4949
Subtracting 891 from 940 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 11:
If we divide 490 by 99, we get 4 and a remainder of 94.
The number 4 becomes the next digit in our result. 
Result so far: 3668.49494
Subtracting 396 from 490 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 12:
If we divide 940 by 99, we get 9 and a remainder of 49.
The next digit of our result is 9. 
Result so far: 3668.494949
Deduct 891 from 940 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 13:
99 goes into 490 4 times with a remainder of 94.
The next digit of our result is 4. 
Result so far: 3668.4949494
Deduct 396 from 490 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 14:
99 goes into 940 9 times with a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 3668.49494949
If we take 891 away from 940, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final result is 3668.49494949 with a remainder of 4.9e-08.
