We're dividing 12199631 by 330 
The aim is to understand the frequency of 330 in 12199631.

Step 1:
When dividing 1 by 330, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 330

Moving on to step 2:
12 divided by 330 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 330

Step 3:
330 can be fit into 121 0 times, resulting in a remainder of 121.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 121 to get 121.
Append the next digit (9) from the dividend to 121 and continue with: 1219 / 330

Let's proceed to step 4:
1219 divided by 330 is 3 with a remainder of 229.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 990 from 1219, we get 229.
Bring next digit (9) of the dividend behind the 229 and repeat the process: 2299 / 330

Moving on to step 5:
330 goes into 2299 6 times with a remainder of 319.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Deduct 1980 from 2299 and we're left with 319.
Fetch the next digit (6) from the dividend, attach it to 319 and continue: 3196 / 330

Moving on to step 6:
330 goes into 3196 9 times with a remainder of 226.
Put 9 as the next digit of the answer. 
Result so far: 369.0
If we subtract 2970 from 3196, we get 226.
Append the next digit (3) from the dividend to 226 and continue with: 2263 / 330

Moving on to step 7:
330 can be fit into 2263 6 times, resulting in a remainder of 283.
Use 6 as the next digit of our solution. 
Result so far: 3696.0
If we subtract 1980 from 2263, we get 283.
Include the next digit (1) from the dividend after 283, then repeat: 2831 / 330

On to step 8:
2831 divided by 330 is 8 with a remainder of 191.
Write down 8 as next digit of the result. 
Result so far: 36968.0
If we subtract 2640 from 2831, we get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Moving on to step 9:
The number 330 fits into 1910 5 times, leaving a remainder of 260.
The next digit of our result is 5. 
Result so far: 36968.5
The remainder is 260 after subtracting 1650 from 1910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 10:
When dividing 2600 by 330, we get 7 with a remainder of 290.
Record the quotient 7 as the next digit in the result. 
Result so far: 36968.57
If we take 2310 away from 2600, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 11:
330 goes into 2900 8 times with a remainder of 260.
The number 8 becomes the next digit in our result. 
Result so far: 36968.578
The remainder is 260 after subtracting 2640 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 12:
When dividing 2600 by 330, we get 7 with a remainder of 290.
Write down 7 as next digit of the result. 
Result so far: 36968.5787
Deduct 2310 from 2600 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 13:
If we divide 2900 by 330, we get 8 and a remainder of 260.
Put 8 as the next digit of the answer. 
Result so far: 36968.57878
The remainder is 260 after subtracting 2640 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 14:
When dividing 2600 by 330, we get 7 with a remainder of 290.
Put 7 as the next digit of the answer. 
Result so far: 36968.578787
Subtract 2310 from 2600 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 15:
The number 330 fits into 2900 8 times, leaving a remainder of 260.
Use 8 as the next digit of our solution. 
Result so far: 36968.5787878
Deduct 2640 from 2900 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 16:
If we divide 2600 by 330, we get 7 and a remainder of 290.
Write down 7 as next digit of the result. 
Result so far: 36968.57878787
The remainder is 290 after subtracting 2310 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

After the division, we end up with 36968.57878787 and a remainder of 2.9e-07.
