666155 divided by 11 
The aim is to understand the frequency of 11 in 666155.

Moving on to step 1:
The number 11 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 11

Step 2:
66 divided by 11 is 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 66 from 66 leaves us with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 11

Step 3:
6 divided by 11 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 60.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 11

Step 4:
11 goes into 61 5 times with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 605.0
If we subtract 55 from 61, we get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 11

Going ahead to step 5:
65 divided by 11 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 6055.0
Subtracting 55 from 65 leaves us with 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 11

Let's proceed to step 6:
If we divide 105 by 11, we get 9 and a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 60559.0
Deduct 99 from 105 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

60 divided by 11 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 60559.5
Subtracting 55 from 60 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
The number 11 fits into 50 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 60559.54
Subtract 44 from 50 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
60 divided by 11 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 60559.545
Deduct 55 from 60 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
11 can be fit into 50 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 60559.5454
Subtracting 44 from 50 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
11 goes into 60 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 60559.54545
The remainder is 5 after subtracting 55 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
When dividing 50 by 11, we get 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 60559.545454
If we take 44 away from 50, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
60 divided by 11 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 60559.5454545
If we take 55 away from 60, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 14:
The number 11 fits into 50 4 times, leaving a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 60559.54545454
The remainder is 6 after subtracting 44 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 60559.54545454 with a remainder of 6e-09.
