Without the TLB, in the paging every data/instruction access requires two memory accesses

One for the page table and one for the data / instruction .

Can any one explain it with diagram (if possible)?

Without TLB two memory access is required if only 1 level of paging is used. Three memory access will be used if 2 level of paging is being used.... and so on.
