We look at the division of 15149 by 11 
The aim is to understand the frequency of 11 in 15149.

Advancing to step 1:
11 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 11

Advancing to step 2:
11 goes into 15 1 times with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 11 from 15 leaves us with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 11

Step 3:
When dividing 41 by 11, we get 3 with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 33 from 41 to get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 11

Step 4:
11 can be fit into 84 7 times, resulting in a remainder of 7.
The next digit of our result is 7. 
Result so far: 137.0
Subtract 77 from 84 to get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 11

On to step 5:
The number 11 fits into 79 7 times, leaving a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 1377.0
The remainder is 2 after subtracting 77 from 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 6:
When dividing 20 by 11, we get 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 1377.1
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 7:
11 can be fit into 90 8 times, resulting in a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 1377.18
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.

On to step 8:
When dividing 20 by 11, we get 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 1377.181
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.

Going ahead to step 9:
11 goes into 90 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 1377.1818
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.

Moving on to step 10:
When dividing 20 by 11, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1377.18181
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 11:
11 can be fit into 90 8 times, resulting in a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 1377.181818
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.

On to step 12:
11 goes into 20 1 times with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1377.1818181
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.

Step 13:
If we divide 90 by 11, we get 8 and a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 1377.18181818
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.

The final outcome is 1377.18181818, with a leftover of 2e-09.
