Let's divide 12039660 by 165
The aim is to understand the frequency of 165 in 12039660.

Let's proceed to step 1:
165 goes into 1 0 times 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.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 165

Let's proceed to step 2:
12 divided by 165 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 165

Advancing to step 3:
120 divided by 165 is 0 with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 120, we get 120.
Bring next digit (3) of the dividend behind the 120 and repeat the process: 1203 / 165

Step 4:
The number 165 fits into 1203 7 times, leaving a remainder of 48.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 1155 from 1203 and we're left with 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 165

On to step 5:
165 goes into 489 2 times with a remainder of 159.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
If we subtract 330 from 489, we get 159.
Bring next digit (6) of the dividend behind the 159 and repeat the process: 1596 / 165

On to step 6:
165 can be fit into 1596 9 times, resulting in a remainder of 111.
Write down 9 as next digit of the result. 
Result so far: 729.0
Deduct 1485 from 1596 and we're left with 111.
Fetch the next digit (6) from the dividend, attach it to 111 and continue: 1116 / 165

Step 7:
The number 165 fits into 1116 6 times, leaving a remainder of 126.
Put 6 as the next digit of the answer. 
Result so far: 7296.0
If we subtract 990 from 1116, we get 126.
Include the next digit (0) from the dividend after 126, then repeat: 1260 / 165

Step 8:
When dividing 1260 by 165, we get 7 with a remainder of 105.
The number 7 becomes the next digit in our result. 
Result so far: 72967.0
Deduct 1155 from 1260 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 9:
The number 165 fits into 1050 6 times, leaving a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 72967.6
The remainder is 60 after subtracting 990 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
When dividing 600 by 165, we get 3 with a remainder of 105.
The next digit of our result is 3. 
Result so far: 72967.63
Subtracting 495 from 600 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 11:
The number 165 fits into 1050 6 times, leaving a remainder of 60.
The next digit of our result is 6. 
Result so far: 72967.636
If we subtract 990 from 1050, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 12:
165 goes into 600 3 times with a remainder of 105.
Record the quotient 3 as the next digit in the result. 
Result so far: 72967.6363
The remainder is 105 after subtracting 495 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 13:
The number 165 fits into 1050 6 times, leaving a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 72967.63636
Deduct 990 from 1050 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 14:
165 goes into 600 3 times with a remainder of 105.
Use 3 as the next digit of our solution. 
Result so far: 72967.636363
If we take 495 away from 600, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 15:
1050 divided by 165 is 6 with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 72967.6363636
The remainder is 60 after subtracting 990 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 16:
165 goes into 600 3 times with a remainder of 105.
The number 3 becomes the next digit in our result. 
Result so far: 72967.63636363
The remainder is 105 after subtracting 495 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The final result is 72967.63636363 with a remainder of 1.05e-07.
