509 in Octal

Decimal 509 in octal conversion provides the detailed information on what is the octal equivalent of (509)10, and the step-by-step work for how to convert the decimal (base-10) number 509 to its octal (base-8) equivalent.

(509)10 in octal is equal to:
(509)10 = (?)8

Perform successive MOD-8 operation for decimal 509, and mark the initial remainder as LSB and the final remainder as MSB as like the below.

MOD-8 of 509	509 / 8 = 63	Remainder is 5 → LSB
MOD-8 of 63	63 / 8 = 7	Remainder is 7
MOD-8 of 7	7 / 8 = 0	Remainder is 7 → MSB

Arrange the remainders from MSB to LSB forms the octal equivalent of 509.
509₁₀ = 775₈

Hence,
509 in octal is 775

where,
509₁₀ is the given decimal number,
10 in 509₁₀ represents the base-10 or decimal number system,
775₈ is the octal equivalent of the decimal 509,
8 in 775₈ represents the base-8 or octal number system.

Important Notes: (509)10 in Octal
The below are some of the important notes to be remembered while converting the (base-10) decimal number 509 into a (base-8) octal equivalent.

1. The first remainder of MOD-8 of 509 is a Least Significant Bit (LSB).
2. The final remainder of MOD-8 of 509 is a Most Significant Bit (MSB).
3. The remainders of MOD-8 of 509 should be written from MSB to LSB to form the octal equivalent for the given decimal number (509)10.
