Let's divide 515429 by 11
The aim is to understand the frequency of 11 in 515429.

Moving on to step 1:
When dividing 5 by 11, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 11

On to step 2:
If we divide 51 by 11, we get 4 and a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 44 from 51 and we're left with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 11

Moving on to step 3:
75 divided by 11 is 6 with a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
If we subtract 66 from 75, we get 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 11

Step 4:
11 goes into 94 8 times with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 468.0
If we subtract 88 from 94, we get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 11

On to step 5:
11 goes into 62 5 times with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 4685.0
Deduct 55 from 62 and we're left with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 11

On to step 6:
If we divide 79 by 11, we get 7 and a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 46857.0
If we subtract 77 from 79, 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:
If we divide 20 by 11, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 46857.1
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.

Moving on to step 8:
11 goes into 90 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 46857.18
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 9:
If we divide 20 by 11, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 46857.181
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 10:
If we divide 90 by 11, we get 8 and a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 46857.1818
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.

Step 11:
If we divide 20 by 11, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 46857.18181
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.

Advancing to step 12:
11 goes into 90 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 46857.181818
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.

Advancing to step 13:
11 can be fit into 20 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 46857.1818181
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.

On to step 14:
90 divided by 11 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 46857.18181818
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 quotient of the division is 46857.18181818, and the remainder is 2e-09.
