The cremation process itself typically takes between 2 to 3 hours. However, the total time from death to receiving the cremated remains can be longer due to several factors:

1. Authorization and Paperwork: Before cremation can take place, the proper legal authorizations must be obtained, which might include death certificates, cremation permits, and authorization from the next of kin or the deceased's legal representative. This paperwork can add time to the process, especially if there are delays or complications.

2. Preparation: The removal of medical devices, jewelry, and other non-combustible items, as well as placing the body in a suitable container, can also add to the overall timeframe.

3. Cooling and Processing: After the cremation process is complete, the remains need time to cool down before they can be processed into a finer consistency. This additional processing can take another hour or more.

4. Crematory Schedule: Depending on how busy the crematory is, there might be a wait before the cremation can take place.

5. Return of the Remains: Once the remains are processed, they are usually placed in a temporary container or an urn provided by the family, after which they can be returned to the family or the designated person.

Considering all these factors, while the cremation itself takes a few hours, the entire process, from death to receiving the ashes, can take several days. In some regions or under particular circumstances, it might even take longer.
