We divide 866886 by 11
The aim is to understand the frequency of 11 in 866886.

Let's proceed to step 1:
11 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 11

Advancing to step 2:
86 divided by 11 is 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 77 from 86 leaves us with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 11

Moving on to step 3:
11 can be fit into 96 8 times, resulting in a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Subtract 88 from 96 to get 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 11

Going ahead to step 4:
88 divided by 11 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 788.0
The remainder is 0 after subtracting 88 from 88.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 11

Step 5:
When dividing 8 by 11, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 7880.0
Subtract 0 from 8 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 11

Step 6:
When dividing 86 by 11, we get 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 78807.0
The remainder is 9 after subtracting 77 from 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
90 divided by 11 is 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 78807.8
Subtracting 88 from 90 leaves us 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.

Step 8:
The number 11 fits into 20 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 78807.81
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.

Step 9:
11 goes into 90 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 78807.818
If we subtract 88 from 90, we 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.

Advancing to step 10:
11 goes into 20 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 78807.8181
Subtracting 11 from 20 leaves us 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.

Moving on to step 11:
The number 11 fits into 90 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 78807.81818
Subtracting 88 from 90 leaves us 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.

Step 12:
If we divide 20 by 11, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 78807.818181
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 13:
11 goes into 90 8 times with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 78807.8181818
If we subtract 88 from 90, we 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 14:
11 can be fit into 20 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 78807.81818181
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.

The final outcome is 78807.81818181, with a leftover of 9e-09.
