We look at the division of 515395 by 11 
The aim is to understand the frequency of 11 in 515395.

Moving on to step 1:
11 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 11

Let's proceed to step 2:
11 goes into 51 4 times with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 44 from 51 and we're left with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 11

Advancing to step 3:
75 divided by 11 is 6 with a remainder of 9.
The next digit of our result is 6. 
Result so far: 46.0
If we subtract 66 from 75, we get 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 11

Going ahead to step 4:
11 goes into 93 8 times with a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 468.0
Deduct 88 from 93 and we're left with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 11

Moving on to step 5:
When dividing 59 by 11, we get 5 with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 4685.0
The remainder is 4 after subtracting 55 from 59.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 11

Moving on to step 6:
11 can be fit into 45 4 times, resulting in a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 46854.0
If we take 44 away from 45, 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 7:
When dividing 10 by 11, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 46854.0
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.

Step 8:
If we divide 100 by 11, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 46854.09
Deduct 99 from 100 and we're left 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.

Advancing to step 9:
11 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 46854.09
If we take 0 away from 10, we end up 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.

Advancing to step 10:
11 can be fit into 100 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 46854.0909
The remainder is 1 after subtracting 99 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
10 divided by 11 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 46854.0909
Subtract 0 from 10 to 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.

Let's proceed to step 12:
100 divided by 11 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 46854.090909
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:
The number 11 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 46854.090909
Subtract 0 from 10 to 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.

On to step 14:
The number 11 fits into 100 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 46854.09090909
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.

The final result is 46854.09090909 with a remainder of 1e-09.
