We look at the division of 144385 by 1 
The aim is to understand the frequency of 1 in 144385.

Step 1:
1 can be fit into 1 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 1 from 1 leaves us with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Advancing to step 2:
1 goes into 4 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 0 after subtracting 4 from 4.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Moving on to step 3:
4 divided by 1 is 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 144.0
If we subtract 4 from 4, we get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 1

Step 4:
3 divided by 1 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 1443.0
Subtracting 3 from 3 leaves us with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Step 5:
When dividing 8 by 1, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 14438.0
If we subtract 8 from 8, we get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Step 6:
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: 144385.0
Subtracting 5 from 5 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.

Step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 144385.0
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.

Advancing to step 8:
1 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 144385.0
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.

The final outcome is 144385.0, with a leftover of 0.0.
