We look at the division of 515080 by 11 
The aim is to understand the frequency of 11 in 515080.

Step 1:
5 divided by 11 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 11

Advancing to step 2:
11 goes into 51 4 times with a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 44 from 51 leaves us with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 11

Going ahead to step 3:
When dividing 75 by 11, we get 6 with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Deduct 66 from 75 and we're left with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 11

On to step 4:
11 goes into 90 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 468.0
The remainder is 2 after subtracting 88 from 90.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 11

Let's proceed to step 5:
11 goes into 28 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 4682.0
If we take 22 away from 28, we end up with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 11

Let's proceed to step 6:
11 goes into 60 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 46825.0
The remainder is 5 after subtracting 55 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
11 can be fit into 50 4 times, resulting in a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 46825.4
Subtract 44 from 50 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
When dividing 60 by 11, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 46825.45
Subtract 55 from 60 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
If we divide 50 by 11, we get 4 and a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 46825.454
If we subtract 44 from 50, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
When dividing 60 by 11, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 46825.4545
Subtracting 55 from 60 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 11:
11 goes into 50 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 46825.45454
Subtract 44 from 50 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
If we divide 60 by 11, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 46825.454545
Subtract 55 from 60 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 13:
50 divided by 11 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 46825.4545454
The remainder is 6 after subtracting 44 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
If we divide 60 by 11, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 46825.45454545
Subtracting 55 from 60 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 46825.45454545 and a remainder of 5e-09.
