Step 1: Check an internal table for the process to determine whether the reference was a valia or invalid memory access.

Step 2: If invalid, terminate the process. If valid, page it in.

Step 3: Find a free frame.

Step 4: Schedule a disk operation to read the page into the newly allocated frame.

Step 5: When disk read is complete, modify the internal table kept with the process and the page table to indicate that the page is in memory.

Step 6: Restart the instruction.
