It would be helpful if you post the example you are working, and what step is not clear.
FYI, you can download these tables from
https://msi.nga.mil/NGAPortal/MSI.portal
(select "publications" from their menu displayed on the left side, and then Sight Reduction Tables for Marine Navigation)
You can also find Vols 2 and 3 of the Air Sight Reduction Tables. Vol 1 of the Air Sight Reduction Tables is date dependent, and you can find them at
http://astro.ukho.gov.uk/nao/publicat/ukaa_usage.html
Of course, these days people probably use an app (if they do celestial at all).
