Let's divide 505880 by 11
The aim is to understand the frequency of 11 in 505880.

Step 1:
5 divided by 11 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 11

Step 2:
11 goes into 50 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 44 from 50 leaves us with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 11

Let's proceed to step 3:
11 goes into 65 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Subtracting 55 from 65 leaves us with 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 11

Going ahead to step 4:
When dividing 108 by 11, we get 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 459.0
Deduct 99 from 108 and we're left with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 11

Moving on to step 5:
11 can be fit into 98 8 times, resulting in a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 4598.0
If we take 88 away from 98, we end up with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 11

On to step 6:
11 goes into 100 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 45989.0
Subtract 99 from 100 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
The number 11 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 45989.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
If we divide 100 by 11, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 45989.09
If we subtract 99 from 100, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
If we divide 10 by 11, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 45989.09
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
100 divided by 11 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 45989.0909
Subtract 99 from 100 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 11:
11 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 45989.0909
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
The number 11 fits into 100 9 times, leaving a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 45989.090909
If we take 99 away from 100, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
11 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 45989.090909
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
11 can be fit into 100 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 45989.09090909
Subtracting 99 from 100 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 45989.09090909, and the remainder is 1e-09.
