254585 ÷ 1 
The aim is to understand the frequency of 1 in 254585.

Let's proceed to step 1:
When dividing 2 by 1, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 2 from 2 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

Moving on to step 2:
The number 1 fits into 5 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 25.0
The remainder is 0 after subtracting 5 from 5.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 1

On to step 3:
4 divided by 1 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 254.0
Subtract 4 from 4 to get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 1

Going ahead to step 4:
When dividing 5 by 1, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 2545.0
If we subtract 5 from 5, we get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

Moving on to step 5:
1 goes into 8 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 25458.0
If we take 8 away from 8, we end up with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Moving on to step 6:
The number 1 fits into 5 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 254585.0
The remainder is 0 after subtracting 5 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
1 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 254585.0
Deduct 0 from 0 and we're left 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.

Advancing to step 8:
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: 254585.0
Subtract 0 from 0 to 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 254585.0, with a leftover of 0.0.
