Instead of multiplying a single digit at a time with a number of digits, single digit products are written down and eventually added.
58*26 would be calculated as
8*6=48
8*20=160
50*6=300
50*20=1000
then add up the four numbers to get 1508.
You can take a look at the site:

The formatting limitations of this site does not allow me to align vertical columns, so it will not be illustrative.
