Example A.1.1. Convert the decimal 12345 to base 26. Method 1: Find the highest power of 26 that is less than 12345. 262 = 676 26 2 = 676 and 263 = 17576 26 3 = 17576 so 262 26 2 is the highest power of 26 that is less than 12345. Next, divide 12345 by 676= 262 676 = 26 2 to find a quotient and remainder.
