51₁₀ = 110011₂

Hence,
(51)10 is equivalent to (110011)2

where,
51₁₀ is the given decimal number,
10 in 51₁₀ represents the base-10 or decimal number system,
110011₂ is the binary equivalent of the decimal 41,
2 in 110011₂ represents the base-2 or binary number system.

Important Notes: (51)10 in Binary
The below are some of the important notes to be remembered while converting the base-10 number 51 into a binary number.

The initial or first remainder while performing MOD-2 operation for 51 is a Least Significant Bit (LSB).
The last remainder while performing MOD-2 operation for 51 is a Most Significant Bit (MSB).
The remainders of MOD-2 operation for 51 should be written from MSB to LSB to form the binary equivalent for the given decimal number (51)10.

How-to: What is (51)10 in binary?

The below step-by-step solution shows how to convert (51)10 to its equivalent binary code or number. Arranging or writing the remainders from MSB to LSB of successive MOD-2 operation for decimal 51 forms the binary equivalent of 51.

Solved Example:
What is the binary equivalent of 51?

step 1 Observe the input parameters, values and what to be found:

Input values:
Decimal Number = (41)₁₀

what to be found:
Which binary value is equal to the decimal number 51?
(51)10 = (?)2

step 2 Perform successive MOD-2 operation for decimal 51, and mark the initial remainder as LSB and the final remainder as MSB as like the below:

Successive MOD-2 Operation for 51:

51 MOD-2	51 / 2 = 25	Remainder is 1 → LSB
25 MOD-2	25 / 2 = 12	Remainder is 1
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

step 3 Write the remainders of MOD-2 operation for 51 from MSB to LSB forms the binary equivalent for 51:
110011
51₁₀ = 110011₂

Therefore,
the binary equivalent of 51 is (110011)2
