We look at the division of 515682 by 1 
The aim is to understand the frequency of 1 in 515682.

Moving on to step 1:
1 can be fit into 5 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 5 away from 5, we end up with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

Moving on to step 2:
The number 1 fits into 1 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 51.0
The remainder is 0 after subtracting 1 from 1.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Going ahead to step 3:
5 divided by 1 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 515.0
If we subtract 5 from 5, we get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

Moving on to step 4:
1 goes into 6 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 5156.0
If we subtract 6 from 6, we get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

Let's proceed to step 5:
The number 1 fits into 8 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 51568.0
Deduct 8 from 8 and we're left with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

Advancing to step 6:
1 goes into 2 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 515682.0
If we take 2 away from 2, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 515682.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 1 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 515682.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 515682.0 and a remainder of 0.0.
