**Steps to reproduce:**
- Install Sales and l10n_cl_edi_stock
- Switch to a Chilean company (e.g. CL Company)
- Create a SO:
  * Customer: [a Chilean customer] (e.g. Blanco Martin & Asociados EIRL)
  * Product: [any storable product with quantity on hand]
- Confirm the invoice
- Go to the delivery
- In "Detailed Operations" tab, add a product with "Done" set to 1
- Save the delivery
=> In "Operations" tab, "Demand" of the added product should be 0
- Do not validate the delivery
- Click on "Print > Delivery Guide SII DTE 52 (CL)"

**Issue:**
A traceback is raised due to a division by 0.

**Cause:**
The Total price of a product line is computed from its "Demand" quantity.
It's also the case for the price unit that is computed with this formula: `(Total price / Demand quantity)` where Demand quantity is 0 in this case.

**Solution:**
The computation can be made from "Done" quantity.
