866877 ÷ 11 
The aim is to understand the frequency of 11 in 866877.

Let's proceed to step 1:
When dividing 8 by 11, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 11

Advancing to step 2:
86 divided by 11 is 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 77 away from 86, we end up with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 11

Step 3:
When dividing 96 by 11, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 78.0
If we subtract 88 from 96, we get 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 11

On to step 4:
11 goes into 88 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 788.0
Subtracting 88 from 88 leaves us with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 11

Let's proceed to step 5:
7 divided by 11 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 7880.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 11

Step 6:
The number 11 fits into 77 7 times, leaving a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 78807.0
Subtract 77 from 77 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
11 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 78807.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 11 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 78807.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 78807.0 with a balance of 0.0.
