We look at the division of 627004 by 1 
The aim is to understand the frequency of 1 in 627004.

Going ahead to step 1:
1 can be fit into 6 6 times, resulting in a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 6 from 6 to get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 1

Moving on to step 2:
1 goes into 2 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
Deduct 2 from 2 and we're left with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 1

On to step 3:
1 can be fit into 7 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 627.0
The remainder is 0 after subtracting 7 from 7.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Advancing to step 4:
If we divide 0 by 1, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 6270.0
Subtract 0 from 0 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Advancing to step 5:
1 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 62700.0
If we subtract 0 from 0, we get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Step 6:
1 goes into 4 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 627004.0
Subtracting 4 from 4 leaves us 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.

Moving on to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 627004.0
The remainder is 0 after subtracting 0 from 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:
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: 627004.0
Subtracting 0 from 0 leaves us 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.

Our division results in 627004.0 with a remaining 0.0.
