When exactly is the timing when this card's [Trash] [All Turns] effect triggers?
It triggers at the timing when this card is in the trash and your [Dorugoramon] would be deleted. [Trash] means that an effect can trigger and activate when the card is in the trash.

If I use this card's [Trash] effect to digivolve when my [Dorugoramon] would be deleted by its DP becoming 0, can I prevent that deletion?
Yes, you can. However, the DP-reducing effect will be carried over after the [Dorugoramon] effect activates and digivolution occurs, therefore deletion will occur again if the DP is still 0 after the effect activates and digivolution occurs.
