We're dividing 25907 by 1 
The aim is to understand the frequency of 1 in 25907.

Advancing to step 1:
2 divided by 1 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 2 away from 2, we end up with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Step 2:
5 divided by 1 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtract 5 from 5 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

Going ahead to step 3:
1 goes into 9 9 times with a remainder of 0.
The next digit of our result is 9. 
Result so far: 259.0
Deduct 9 from 9 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

Moving on to step 4:
0 divided by 1 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2590.0
Subtracting 0 from 0 leaves us with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

Advancing to step 5:
The number 1 fits into 7 7 times, leaving a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 25907.0
If we take 7 away from 7, 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.

Moving on to step 6:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 25907.0
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.

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: 25907.0
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.

The final outcome is 25907.0, with a leftover of 0.0.
