We look at the division of 818449 by 11 
The aim is to understand the frequency of 11 in 818449.

Advancing to step 1:
When dividing 8 by 11, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 11

On to step 2:
If we divide 81 by 11, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 77 from 81 leaves us with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 11

Going ahead to step 3:
11 goes into 48 4 times with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
Subtract 44 from 48 to get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 11

Moving on to step 4:
11 goes into 44 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 744.0
If we subtract 44 from 44, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 11

Advancing to step 5:
11 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 7440.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 11

On to step 6:
The number 11 fits into 49 4 times, leaving a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 74404.0
If we take 44 away from 49, 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.

Let's proceed to step 7:
50 divided by 11 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 74404.4
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 8:
11 goes into 60 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 74404.45
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.

Going ahead to step 9:
When dividing 50 by 11, we get 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 74404.454
Deduct 44 from 50 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.

On to step 10:
If we divide 60 by 11, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 74404.4545
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.

Advancing to step 11:
11 can be fit into 50 4 times, resulting in a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 74404.45454
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.

On to step 12:
11 goes into 60 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 74404.454545
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.

Step 13:
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: 74404.4545454
If we subtract 44 from 50, we 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.

Let's proceed to step 14:
60 divided by 11 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 74404.45454545
If we subtract 55 from 60, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 74404.45454545, with a leftover of 5e-09.
