proplem in division

[marwa]

helo,

i'm new here and i need some help for a project

the problem is in a process that is used to display a number ranges from 0 to 9999 on a seven segment

the proplem i face is related ti division

here is the process

signal seg: integer ; -- this signal is the number will be displayed.

output : process ( seg )

begin

if ( seg < 10 ) then
anode <= "0111";
digit3 <= seg ;


elsif ( seg < 100) then
anode <= "0011" ;
digit2 <= seg /10 ;
digit3 <= seg rem 10 ;

elsif ( seg < 1000) then
anode <= "0001";

digit1 <= seg / 100 ;
REM0 <= seg rem 100 ;

digit2 <= REM0 /10 ;
digit3 <= REM0 rem 10 ;

else
anode <= "0000";
digit0 <= seg / 1,000 ;
REM0 <= seg rem 1,000 ;

digit1 <= REM0 / 100 ;
REM1 <= REM0 rem 100 ;

digit2 <= REM1 /10 ;
digit3 <= REM1 rem 10 ;

end if;

end process;




help !!!
