We look at the division of 660849 by 11 
The aim is to understand the frequency of 11 in 660849.

Going ahead to step 1:
6 divided by 11 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 11

Going ahead to 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 (0) from the dividend to 0 and continue with: 0 / 11

On to step 3:
11 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 60.0
Subtract 0 from 0 to get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 11

Going ahead to step 4:
11 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 600.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 11

Advancing to step 5:
84 divided by 11 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 6007.0
Subtracting 77 from 84 leaves us with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 11

On to step 6:
79 divided by 11 is 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 60077.0
If we take 77 away from 79, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
The number 11 fits into 20 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 60077.1
If we take 11 away from 20, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 8:
When dividing 90 by 11, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 60077.18
Subtract 88 from 90 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
When dividing 20 by 11, we get 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 60077.181
If we take 11 away from 20, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
The number 11 fits into 90 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 60077.1818
Subtract 88 from 90 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
The number 11 fits into 20 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 60077.18181
The remainder is 9 after subtracting 11 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 12:
90 divided by 11 is 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 60077.181818
The remainder is 2 after subtracting 88 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
11 goes into 20 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 60077.1818181
If we subtract 11 from 20, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 14:
11 goes into 90 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 60077.18181818
The remainder is 2 after subtracting 88 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 60077.18181818 with a remaining 2e-09.
