We're dividing 5259 by 1 
The aim is to understand the frequency of 1 in 5259.

Advancing to step 1:
When dividing 5 by 1, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 5 from 5 to get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 1

Step 2:
If we divide 2 by 1, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 52.0
Subtract 2 from 2 to get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Going ahead to step 3:
1 can be fit into 5 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 525.0
Subtract 5 from 5 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

On to step 4:
1 can be fit into 9 9 times, resulting in a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 5259.0
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.

Step 5:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5259.0
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.

Step 6:
When dividing 0 by 1, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5259.0
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 5259.0 with a remaining 0.0.
