    The below is the example problem with step by step work to find what is 18 decimal in binary.
    18 Decimal To Binary Conversion:
    step 1 Perform the successive MOD operation by 2 for the given decimal number 18 and note down the remainder (either 0 or 1) for each operation. The last remainder is the MSB (most significant bit) and the first remainder is the LSB (least significant bit).
    18 / 2 = 9   : Remainder is 0 → LSB
    9 / 2 = 4   : Remainder is 1
    4 / 2 = 2   : Remainder is 0
    2 / 2 = 1   : Remainder is 0
    1 / 2 = 0   : Remainder is 1 → MSB

    step 2 Write the remainders from MSB to LSB provide the equivalent binary number
    10010
    1810 = 100102
