423687 ÷ 11 
The aim is to understand the frequency of 11 in 423687.

Moving on to step 1:
11 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 11

Step 2:
11 can be fit into 42 3 times, resulting in a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 33 from 42 leaves us with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 11

On to step 3:
11 can be fit into 93 8 times, resulting in a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 38.0
If we subtract 88 from 93, we get 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 11

Going ahead to step 4:
11 can be fit into 56 5 times, resulting in a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 385.0
If we subtract 55 from 56, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 11

Going ahead to step 5:
The number 11 fits into 18 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 3851.0
Subtract 11 from 18 to get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 11

On to step 6:
When dividing 77 by 11, we get 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 38517.0
Subtract 77 from 77 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
When dividing 0 by 11, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 38517.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
0 divided by 11 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 38517.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 38517.0 with a remainder of 0.0.
