Maybe this?

array=[0,12,14,16,22,43,12,35,67,88,12,11,5,6,1,3]
narray=n_elements(array)
nlen=1
npiece=4
nblock0=nlen*npiece
nblock=narray/nblock0

array=reform(array,nlen,narray/nlen)
off0=indgen(npiece,nblock)

for i=0,npiece-1 do $
print,reform(array[*,off0[i,*]],narray/npiece)

The last loop is just for showing the 4 array, you probably want to
store them:

array0=reform(array[*,off0[0,*]],narray/npiece)
...
