We look at the division of 539640 by 11 
The aim is to understand the frequency of 11 in 539640.

Let's proceed to step 1:
11 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 11

Step 2:
The number 11 fits into 53 4 times, leaving a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 44 from 53, we get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 11

Let's proceed to step 3:
If we divide 99 by 11, we get 9 and a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 49.0
If we subtract 99 from 99, we get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 11

Step 4:
The number 11 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 490.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 11

On to step 5:
11 can be fit into 64 5 times, resulting in a remainder of 9.
The next digit of our result is 5. 
Result so far: 4905.0
Subtract 55 from 64 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 11

Moving on to step 6:
90 divided by 11 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 49058.0
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.

Going ahead to step 7:
11 goes into 20 1 times with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 49058.1
The remainder is 9 after subtracting 11 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 8:
The number 11 fits into 90 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 49058.18
If we subtract 88 from 90, 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.

Going ahead to step 9:
20 divided by 11 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 49058.181
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.

On to step 10:
The number 11 fits into 90 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 49058.1818
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.

Advancing to step 11:
If we divide 20 by 11, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 49058.18181
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 12:
11 can be fit into 90 8 times, resulting in a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 49058.181818
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.

Let's proceed to step 13:
The number 11 fits into 20 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 49058.1818181
Subtract 11 from 20 to 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.

Advancing to step 14:
11 goes into 90 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 49058.18181818
Subtract 88 from 90 to 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.

The final outcome is 49058.18181818, with a leftover of 2e-09.
