How to append data in the content of Notepad

I used the command line (for /l %i in (00000000,1,99999999) do @echo %i > dict.txt) to create a file

After execution, the content of dict.txt is:
00000000
00000001
...........
99999999
Now I want to add the same data in front of each line of data, such as 130, or 139 and so on, and then get

Such as? 13000000000

13000000001

13099999999

Dear "great immortals", how can I operate in batches?

Re sncffb
How do you get numbers with a prefix of 0 like 00000000? In my test, I can only get 0, 1,...10,...100, so I used the recursive binary search method in another reply. Among them, it mentions how to add a prefix to a number.

What Willsort said is correct. You can't directly get 01 02 03 04...
