389 in Binary

Decimal 389 in binary conversion provides the detailed information on what is the binary equivalent of (389)10, and the step-by-step work for how to convert the decimal (base-10) number 389 to its binary (base-2) equivalent.

(389)10 in binary is equal to:
(389)₁₀ = (?)₂
Perform successive MOD-2 operation for decimal 389, and mark the initial remainder as LSB and the final remainder as MSB as like the below.

389 MOD-2	389 / 2 = 194	Remainder is 1 → LSB
194 MOD-2	194 / 2 = 97	Remainder is 0
97 MOD-2	97 / 2 = 48	Remainder is 1
48 MOD-2	48 / 2 = 24	Remainder is 0
24 MOD-2	24 / 2 = 12	Remainder is 0
12 MOD-2	12 / 2 = 6	Remainder is 0
6 MOD-2	6 / 2 = 3	Remainder is 0
3 MOD-2	3 / 2 = 1	Remainder is 1
1 MOD-2	1 / 2 = 0	Remainder is 1 → MSB

Arrange the remainders from MSB to LSB forms the binary equivalent of 389.
389₁₀ = 110000101₂

Hence,
389 in binary is 110000101

where,
389₁₀ is the given decimal number,
10 in 389₁₀ represents the base-10 or decimal number system,
110000101₂ is the binary equivalent of the decimal 41,
2 in 110000101₂ represents the base-2 or binary number system.

Important Notes: (389)10 in Binary
The below are some of the important notes to be remembered while converting the base-10 number 389 into a binary number.

1. The initial or first remainder while performing MOD-2 operation for 389 is a Least Significant Bit (LSB).
2. The last remainder while performing MOD-2 operation for 389 is a Most Significant Bit (MSB).
3. The remainders of MOD-2 operation for 389 should be written from MSB to LSB to form the binary equivalent for the given decimal number (389)10.
