## Work to Find What is 40 Decimal in Binary

The below is the example problem with step by step work to find what is 40 decimal in binary.
40 Decimal To Binary Conversion:
step 1 Perform the successive MOD operation by 2 for the given decimal number 40 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).
40 / 2 = 20   : Remainder is 0 → LSB
20 / 2 = 10   : Remainder is 0
10 / 2 = 5   : Remainder is 0
5 / 2 = 2   : Remainder is 1
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
101000
4010 = 1010002
