How it works

Binary is base 2: each digit is a bit worth a power of two (1, 2, 4, 8, 16, 32 …). To convert a decimal number to binary, divide it by 2 again and again, writing down each remainder (0 or 1), until the quotient reaches 0. The binary number is the remainders read from the last one to the first. To check, add the powers of two where the bits are 1.
