I'm using Magento CE 1.9.2
For a while I was trying to disable OnePage and multishipping.
Shipping Settings => Options => Allow Shipping to Multiple Addresses value to 'No'
Checkout => Checkout setting = > Enable OnePage Checkout value to 'No'
The problem is that if these two options are set to No, there is no button
Proceed to Checkout display on the cart page.
All I want a multi-step checkout and not want to allow multi-shipping.
