We look at the division of 431159 by 11 
The aim is to understand the frequency of 11 in 431159.

Going ahead to step 1:
4 divided by 11 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 11

Moving on to step 2:
43 divided by 11 is 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 3.0
If we take 33 away from 43, we end up with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 11

Moving on to step 3:
If we divide 101 by 11, we get 9 and a remainder of 2.
The next digit of our result is 9. 
Result so far: 39.0
If we subtract 99 from 101, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 11

Step 4:
21 divided by 11 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 391.0
If we subtract 11 from 21, we get 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 11

On to step 5:
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: 3919.0
Subtracting 99 from 105 leaves us with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 11

Moving on to step 6:
When dividing 69 by 11, we get 6 with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 39196.0
Subtracting 66 from 69 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
The number 11 fits into 30 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 39196.2
Subtracting 22 from 30 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
The number 11 fits into 80 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 39196.27
Subtracting 77 from 80 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
11 goes into 30 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 39196.272
Subtract 22 from 30 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
80 divided by 11 is 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 39196.2727
Deduct 77 from 80 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
30 divided by 11 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 39196.27272
If we take 22 away from 30, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
11 goes into 80 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 39196.272727
Deduct 77 from 80 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
11 can be fit into 30 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 39196.2727272
The remainder is 8 after subtracting 22 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
11 can be fit into 80 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 39196.27272727
If we take 77 away from 80, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 39196.27272727 and a remainder of 3e-09.
