Converting a hexadecimal number to octal without a calculator involves first converting the hexadecimal number to binary, then grouping the binary digits into groups of three, and finally converting each group to its octal equivalent. Here's a step-by-step guide for hexadecimal number57F:

516 = 01012

716 = 01112

F16 = 11112
