We look at the division of 263518 by 11 
The aim is to understand the frequency of 11 in 263518.

Advancing to step 1:
11 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 11

Step 2:
11 goes into 26 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 22 from 26, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 11

Advancing to step 3:
When dividing 43 by 11, we get 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we take 33 away from 43, we end up with 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 11

Advancing to step 4:
11 can be fit into 105 9 times, resulting in a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 239.0
Deduct 99 from 105 and we're left with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 11

Let's proceed to step 5:
The number 11 fits into 61 5 times, leaving a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 2395.0
Subtracting 55 from 61 leaves us with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 11

Advancing to step 6:
68 divided by 11 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 23956.0
Deduct 66 from 68 and we're left 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 7:
The number 11 fits into 20 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 23956.1
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.

Let's proceed to step 8:
When dividing 90 by 11, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 23956.18
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.

On to step 9:
If we divide 20 by 11, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 23956.181
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.

Advancing to step 10:
If we divide 90 by 11, we get 8 and a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 23956.1818
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.

Step 11:
20 divided by 11 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 23956.18181
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.

On to step 12:
11 goes into 90 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 23956.181818
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.

Going ahead to step 13:
If we divide 20 by 11, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 23956.1818181
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.

Advancing to step 14:
11 can be fit into 90 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 23956.18181818
The remainder is 2 after subtracting 88 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 23956.18181818 with a remaining 2e-09.
