Hi,
Here's one way:
VARIABLE     input_string     VARCHAR2 (4000)
EXEC  :input_string := 'aaaa,bbbb,cccc,dddd,eeee,ffff,gggg,hhhh,iiiiii,jjjj';
WITH     got_sub_string     AS
     SELECT     CEIL (LEVEL / 4)     AS r_num
     ,     MOD  (LEVEL,  4) + 1     AS c_num
     ,     REGEXP_SUBSTR ( :input_string
                     , '[^,]+'
                     , 1
                     , LEVEL
                     )          AS sub_string
     FROM    dual
     CONNECT BY     LEVEL <= 1 + LENGTH ( :input_string)
                       - LENGTH ( REPLACE ( :input_string
SELECT       MIN (CASE WHEN c_num = 1 THEN sub_string END)     AS col_1
,       MIN (CASE WHEN c_num = 2 THEN sub_string END)     AS col_2
,       MIN (CASE WHEN c_num = 3 THEN sub_string END)     AS col_3
,       MIN (CASE WHEN c_num = 4 THEN sub_string END)     AS col_4
FROM       got_sub_string
GROUP BY  r_num
ORDER BY  r_num
;I assumed seeral things, such as your version of Oracle. This works in Oracle 10 (and up), but could be simplified some in Oracle 11.
