if im using std_logic_vector type...how?

generic(n: natural :=25);

port( divCLK: in std_logic;

level:in std_logic_vector (3 downto 0);

Q: out std_logic);

end countersystem;

----------------------------------------------------

architecture behv of countersystem is

signal clkdiv: std_logic_vector(n-1 downto 0);

begin

process(divCLK)

begin

if rising_edge(divCLK) then

clkdiv <= clkdiv + 1;

end if;

Q<=clkdiv(24);

from this i can get 1Hz, but how to get 2Hz,3Hz and so on from these coding...

is it

Q<=clkdiv(23),Q<=clkdiv(22)...and so on?
