We look at the division of 507556 by 11 
The aim is to understand the frequency of 11 in 507556.

Advancing to step 1:
When dividing 5 by 11, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 11

Moving on to step 2:
The number 11 fits into 50 4 times, leaving a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 44 from 50 and we're left with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 11

Advancing to step 3:
When dividing 67 by 11, we get 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 46.0
The remainder is 1 after subtracting 66 from 67.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 11

Let's proceed to step 4:
When dividing 15 by 11, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 461.0
Subtracting 11 from 15 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 11

Moving on to step 5:
The number 11 fits into 45 4 times, leaving a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4614.0
Deduct 44 from 45 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 11

Advancing to step 6:
The number 11 fits into 16 1 times, leaving a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 46141.0
Subtract 11 from 16 to 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.

Advancing to step 7:
50 divided by 11 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 46141.4
If we subtract 44 from 50, we 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 8:
11 goes into 60 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 46141.45
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 9:
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: 46141.454
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.

On to step 10:
The number 11 fits into 60 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 46141.4545
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.

On to step 11:
The number 11 fits into 50 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 46141.45454
If we subtract 44 from 50, we 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.

On to step 12:
The number 11 fits into 60 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 46141.454545
If we take 55 away from 60, 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.

Step 13:
11 can be fit into 50 4 times, resulting in a remainder of 6.
The next digit of our result is 4. 
Result so far: 46141.4545454
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.

On to step 14:
11 goes into 60 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 46141.45454545
If we take 55 away from 60, 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.

The final result is 46141.45454545 with a remainder of 5e-09.
