We look at the division of 425969 by 1 
The aim is to understand the frequency of 1 in 425969.

Advancing to step 1:
1 can be fit into 4 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 4 from 4 leaves us with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 1

Step 2:
1 can be fit into 2 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtract 2 from 2 to get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 1

Let's proceed to step 3:
The number 1 fits into 5 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 425.0
The remainder is 0 after subtracting 5 from 5.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

Let's proceed to step 4:
The number 1 fits into 9 9 times, leaving a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 4259.0
Subtracting 9 from 9 leaves us with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

Advancing to step 5:
The number 1 fits into 6 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 42596.0
Subtract 6 from 6 to get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

Moving on to step 6:
1 can be fit into 9 9 times, resulting in a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 425969.0
If we subtract 9 from 9, 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.

Moving on to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 425969.0
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.

Step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 425969.0
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.

The final result is 425969.0 with a remainder of 0.0.
