We look at the division of 811699 by 11 
The aim is to understand the frequency of 11 in 811699.

Going ahead to step 1:
11 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 11

Moving on to step 2:
81 divided by 11 is 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 77 from 81, we get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 11

Let's proceed to step 3:
11 goes into 41 3 times with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
If we subtract 33 from 41, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 11

Advancing to step 4:
86 divided by 11 is 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 737.0
Subtract 77 from 86 to get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 11

On to step 5:
99 divided by 11 is 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 7379.0
If we subtract 99 from 99, we get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 11

Going ahead to step 6:
11 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 73790.0
Subtracting 0 from 9 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.

Let's proceed to step 7:
11 can be fit into 90 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 73790.8
If we take 88 away from 90, 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.

Going ahead to step 8:
11 goes into 20 1 times with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 73790.81
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:
90 divided by 11 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 73790.818
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.

Moving on to step 10:
11 can be fit into 20 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 73790.8181
Deduct 11 from 20 and we're left 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 11:
When dividing 90 by 11, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 73790.81818
If we take 88 away from 90, 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.

Advancing to step 12:
If we divide 20 by 11, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 73790.818181
Subtract 11 from 20 to 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.

Going ahead to step 13:
When dividing 90 by 11, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 73790.8181818
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.

On to 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: 73790.81818181
Subtract 11 from 20 to 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.

Our division results in 73790.81818181 with a remaining 9e-09.
