I need to create an approval workflow that has many levels, the approval would go like this:

Step 1:Manager Approval

Step 2: Director Approval

Step 3: Finance Approval
Step 4: VP Approval

Step 5: CEO Approval

At each step the user sent the approval request would have to select the next level approver to send them an approval task all the way up until it gets to Step 5 for the final CEO approval.

What is the best way to accomplish this?
