If you mean, for example, divide one hexadecimal number by another: In any number base, you can use basically the same method you use with decimal numbers - in the case of division, the "long division". However, you have to use the corresponding multiplication table, for example, the multiplication table for multiplying two hexadecimal digits, with a hexadecimal result.
The hexadecimal number system is one using 16 as the base instead of the more familiar ten which we use in the decimal system.

Computer engineers use to use the hexadecimal code to program computers, or the base 16. Hexadecimal numbers use the digits 0 through 9, plus the letters A through F to represent the digits 10 through 15.
Each 4 bits of binary can make 1 hexadecimal digit. There are 16 hexadecimal characters including zero. This can be shown by the equation 2^4 = 16.

That would be a Hexadecimal code.
Any data is stored internally in the computer as binary digits, but those are "bulky" - you need 4 binary digits for every hexadecimal digit, so hexadecimal is really a kind of shortcut to write out binary numbers.Decimal is another option, but conversion between binary and decimal is more cumbersome than with hexadecimal. Therefore, for the new IP addresses (IP version 6), they decided to write them down in hexadecimal, instead of the decimal that is used for IPv4.
The first use of the term hexadecimal dates to 1954. It is unclear who invented the current hexadecimal notation - most likely IBM. Not all computers used hexadecimal until the end of the 70s or later. Hewlett-Packard continued to use octal instead of hexadecimal until after 1980.

hexadecimal, eg. 1ABH = 1AB(16) = 427(10)
The highest numerical digit is 9, but hexadecimal follows that with letters going to F. So in hexadecimal, F would be the highest digit.
The physical address is in binary, just like everything else in the computer. Other bases, such as octal, (decimal,) and hexadecimal are simply representations for our convenience.
Each hexadecimal digit represents four binary digits (bits) (also called a "nibble"), and the primary use of hexadecimal notation is as a human-friendly representation of values in computing and digital electronics. For example, binary coded byte values can range from 0 to 255 (decimal) but may be more conveniently represented as two hexadecimal digits in the range 00 through FF. Hexadecimal is also commonly used to represent computer memory adresses.
