Text separation

[TalkNet_TechnoS]

I need to separate a string of scanned text, in several columns.
Specifically, the barcode of the identity document.
When scanning it, it is presented in the following format:

Procedure N ° @ Surname @ Names @ Sex @ DNI @ Exemplary @ Date Nac @ Date Emission

and I want to separate it in the corresponding fields. Find() only finds me the first match. Is there an expression that fulfills this function?
Thank you very much already
