We look at the division of 150537 by 11 
The aim is to understand the frequency of 11 in 150537.

Going ahead to step 1:
The number 11 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 11

On to step 2:
11 can be fit into 15 1 times, resulting in a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 4 after subtracting 11 from 15.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 11

Advancing to step 3:
If we divide 40 by 11, we get 3 and a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 33 from 40 and we're left with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 11

Step 4:
If we divide 75 by 11, we get 6 and a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 136.0
Subtract 66 from 75 to get 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 11

Moving on to step 5:
If we divide 93 by 11, we get 8 and a remainder of 5.
The next digit of our result is 8. 
Result so far: 1368.0
Deduct 88 from 93 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 11

Going ahead to step 6:
The number 11 fits into 57 5 times, leaving a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 13685.0
Subtracting 55 from 57 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.

Step 7:
If we divide 20 by 11, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 13685.1
If we take 11 away from 20, we end up 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 8:
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: 13685.18
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.

Let's proceed to step 9:
If we divide 20 by 11, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 13685.181
If we take 11 away from 20, we end up 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 10:
The number 11 fits into 90 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 13685.1818
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.

Advancing to step 11:
If we divide 20 by 11, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 13685.18181
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.

Let's proceed to step 12:
11 can be fit into 90 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 13685.181818
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 13:
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: 13685.1818181
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.

Moving on to step 14:
11 goes into 90 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 13685.18181818
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.

Our division results in 13685.18181818 with a remaining 2e-09.
