You can use Hierarchical Query along with REGEXP_SUBSTR() function :

SELECT id, REGEXP_SUBSTR(text,'[^#]+',1,level)||'#' AS text
  FROM t
 CONNECT BY level <= REGEXP_COUNT(text,'#')
    AND PRIOR SYS_GUID() IS NOT NULL
    AND PRIOR id = id;

ID      TEXT
------  ---------------------
182234  ZO-Z-000-4OB-566WD1#
182234  ZO-Z-000-4OB-566WD#
182234  ZO-Z-000-4OB-566WD2#
182245  ZO-Z-000-4OB-567WD1#
182245  ZO-Z-000-4OB-567WD#

Wait, if you are on 18c. The below is how you solve it:

select * from t,
lateral
(
    select REGEXP_SUBSTR(text,'[^#]+',1,level)||'#' as new_text
    from dual 
    connect by REGEXP_SUBSTR(text,'[^#]+',1,level) is not null
)
