We look at the division of 253258 by 11 
The aim is to understand the frequency of 11 in 253258.

Step 1:
11 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 11

Going ahead to step 2:
The number 11 fits into 25 2 times, leaving a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 3 after subtracting 22 from 25.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 11

Going ahead to step 3:
When dividing 33 by 11, we get 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 23.0
Deduct 33 from 33 and we're left with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 11

Advancing to step 4:
When dividing 2 by 11, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 230.0
Subtract 0 from 2 to get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 11

Step 5:
25 divided by 11 is 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2302.0
Deduct 22 from 25 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 11

Step 6:
If we divide 38 by 11, we get 3 and a remainder of 5.
The next digit of our result is 3. 
Result so far: 23023.0
If we take 33 away from 38, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
50 divided by 11 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 23023.4
Subtracting 44 from 50 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
The number 11 fits into 60 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 23023.45
The remainder is 5 after subtracting 55 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
50 divided by 11 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 23023.454
Subtracting 44 from 50 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
11 goes into 60 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 23023.4545
If we subtract 55 from 60, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 11:
50 divided by 11 is 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 23023.45454
Subtract 44 from 50 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 12:
11 can be fit into 60 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 23023.454545
Subtracting 55 from 60 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 13:
The number 11 fits into 50 4 times, leaving a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 23023.4545454
The remainder is 6 after subtracting 44 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
When dividing 60 by 11, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 23023.45454545
If we subtract 55 from 60, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 23023.45454545 and a remainder of 5e-09.
