Let's divide 558503 by 11
The aim is to understand the frequency of 11 in 558503.

On to step 1:
11 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 11

Advancing to step 2:
11 can be fit into 55 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 55 from 55, we get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 11

On to step 3:
If we divide 8 by 11, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
Subtract 0 from 8 to get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 11

Moving on to step 4:
The number 11 fits into 85 7 times, leaving a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 507.0
Subtract 77 from 85 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 11

Going ahead to step 5:
If we divide 80 by 11, we get 7 and a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 5077.0
Subtract 77 from 80 to get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 11

Going ahead to step 6:
11 goes into 33 3 times with a remainder of 0.
The next digit of our result is 3. 
Result so far: 50773.0
Subtracting 33 from 33 leaves us 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.

Let's proceed to step 7:
11 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 50773.0
If we take 0 away from 0, we end up 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.

Going ahead to step 8:
0 divided by 11 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 50773.0
Subtract 0 from 0 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.

The final outcome is 50773.0, with a leftover of 0.0.
