Filtered data value is so long

I am using stm32f4 discovery board.
from ADC I take 1ksample/sec and accumulate it.
after accumulation of 30Ksamples, process it through band pass filter.
output of band pass filter is very large +ve and -ve values ex.3267832. it is not in range of voltage level i fed for filtering.
any idea?? how can i get filter output in my input range?
do i need to divide it with some fix value?

and can i send that filtered data 30K values to output (DAC) for understanding of filter output. this 30K value need to send every 1sec.

thanks in advance
