    321 in Binary

    Decimal 321 in binary conversion provides the detailed information on what is the binary equivalent of (321)10, and the step-by-step work for how to convert the decimal (base-10) number 321 to its binary (base-2) equivalent.

    (321)10 in binary is equal to:
    (321)10 = (?)2
    Perform successive MOD-2 operation for decimal 321, and mark the initial remainder as LSB and the final remainder as MSB as like the below.

    321 MOD-2     321 / 2 = 160  Remainder is 1 → LSB
    160 MOD-2     160 / 2 = 80  Remainder is 0
    80 MOD-2     80 / 2 = 40  Remainder is 0
    40 MOD-2     40 / 2 = 20  Remainder is 0
    20 MOD-2     20 / 2 = 10  Remainder is 0
    10 MOD-2     10 / 2 = 5  Remainder is 0
    5 MOD-2     5 / 2 = 2  Remainder is 1
    2 MOD-2     2 / 2 = 1  Remainder is 0
    1 MOD-2     1 / 2 = 0  Remainder is 1 → MSB
    Arrange the remainders from MSB to LSB forms the binary equivalent of 321.
    32110 = 1010000012

    Hence,
    321 in binary is 101000001

    where,
    32110 is the given decimal number,
    10 in 32110 represents the base-10 or decimal number system,
    1010000012 is the binary equivalent of the decimal 41,
    2 in 1010000012 represents the base-2 or binary number system.

    Important Notes: (321)10 in Binary
    The below are some of the important notes to be remembered while converting the base-10 number 321 into a binary number.
    1. The initial or first remainder while performing MOD-2 operation for 321 is a Least Significant Bit (LSB).
    2. The last remainder while performing MOD-2 operation for 321 is a Most Significant Bit (MSB).
    3. The remainders of MOD-2 operation for 321 should be written from MSB to LSB to form the binary equivalent for the given decimal number (321)10.
