We're dividing 506431 by 11 
The aim is to understand the frequency of 11 in 506431.

Going ahead to step 1:
The number 11 fits into 5 0 times, leaving 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

Going ahead to step 2:
When dividing 50 by 11, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 44 from 50 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 11

Step 3:
The number 11 fits into 66 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 46.0
Subtract 66 from 66 to get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 11

Moving on to step 4:
When dividing 4 by 11, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 460.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 11

Moving on to step 5:
11 can be fit into 43 3 times, resulting in a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 4603.0
The remainder is 10 after subtracting 33 from 43.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 11

Moving on to step 6:
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: 46039.0
If we subtract 99 from 101, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
The number 11 fits into 20 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 46039.1
If we take 11 away from 20, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 8:
The number 11 fits into 90 8 times, leaving a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 46039.18
Subtracting 88 from 90 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
When dividing 20 by 11, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 46039.181
If we subtract 11 from 20, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
If we divide 90 by 11, we get 8 and a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 46039.1818
Subtracting 88 from 90 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
20 divided by 11 is 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 46039.18181
Deduct 11 from 20 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 12:
90 divided by 11 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 46039.181818
Deduct 88 from 90 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
11 can be fit into 20 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 46039.1818181
If we subtract 11 from 20, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 14:
When dividing 90 by 11, we get 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 46039.18181818
The remainder is 2 after subtracting 88 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 46039.18181818, with a leftover of 2e-09.
