Let's divide 11617042 by 666
The aim is to understand the frequency of 666 in 11617042.

On to step 1:
If we divide 1 by 666, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 666

On to step 2:
666 can be fit into 11 0 times, resulting in a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 11, we end up with 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 666

Step 3:
The number 666 fits into 116 0 times, leaving a remainder of 116.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 116 after subtracting 0 from 116.
Include the next digit (1) from the dividend after 116, then repeat: 1161 / 666

Moving on to step 4:
666 goes into 1161 1 times with a remainder of 495.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 666 from 1161, we get 495.
Fetch the next digit (7) from the dividend, attach it to 495 and continue: 4957 / 666

On to step 5:
When dividing 4957 by 666, we get 7 with a remainder of 295.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we take 4662 away from 4957, we end up with 295.
Grab the next digit (0) from the dividend, add it to 295, then carry on: 2950 / 666

On to step 6:
666 can be fit into 2950 4 times, resulting in a remainder of 286.
Use 4 as the next digit of our solution. 
Result so far: 174.0
If we take 2664 away from 2950, we end up with 286.
Take the next digit (4) from the dividend and append it to 286, then repeat: 2864 / 666

Moving on to step 7:
If we divide 2864 by 666, we get 4 and a remainder of 200.
Write down 4 as next digit of the result. 
Result so far: 1744.0
If we take 2664 away from 2864, we end up with 200.
Take the next digit (2) from the dividend and append it to 200, then repeat: 2002 / 666

Let's proceed to step 8:
If we divide 2002 by 666, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 17443.0
If we subtract 1998 from 2002, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
666 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 17443.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
400 divided by 666 is 0 with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 17443.0
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 17443.0 with a remainder of 0.4.
