We look at the division of 867131 by 11 
The aim is to understand the frequency of 11 in 867131.

Advancing to step 1:
11 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 11

Going ahead 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 (7) from the dividend, attach it to 9 and continue: 97 / 11

Advancing to step 3:
If we divide 97 by 11, we get 8 and a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
If we subtract 88 from 97, we get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 11

Going ahead to step 4:
91 divided by 11 is 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 788.0
If we subtract 88 from 91, we get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 11

Advancing to step 5:
When dividing 33 by 11, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 7883.0
Subtracting 33 from 33 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 11

On to step 6:
The number 11 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 78830.0
If we subtract 0 from 1, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
When dividing 10 by 11, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 78830.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
When dividing 100 by 11, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 78830.09
If we take 99 away from 100, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
11 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 78830.09
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
100 divided by 11 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 78830.0909
If we subtract 99 from 100, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 11:
When dividing 10 by 11, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 78830.0909
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
11 can be fit into 100 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 78830.090909
Subtract 99 from 100 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 13:
If we divide 10 by 11, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 78830.090909
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
The number 11 fits into 100 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 78830.09090909
Deduct 99 from 100 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 78830.09090909 and a remainder of 1e-09.
