About Decimal to Binary Conversion
Every decimal number has an exact binary representation. The standard method is repeated division by 2: divide your number by 2, note the remainder, then repeat with the quotient until you reach 0. Read the remainders from bottom to top and you have the binary number.
For example, 214 in decimal is 11010110 in binary — 8 bits, which fits in a single byte. This tool also shows the hex and octal equivalents alongside the binary output.
