Convert Decimal to Binary

The very first way to convert is dividing the decimal number by 2 eg: 87 87/2 = 43 - 1 43/2 = 21 - 1 21/2 = 10 - 1 10/2 = 05 - 0 05/2 = 02 - 1 02/2 = 1 - 0 so the binary for the decimal number 87 is 1010111 also there is another way to easily find that is exponent method 2 power zero is 1 2 to the power one is 2 ..... so it comes as 1, 2, 4, 8, 16, 32, 64,128.... so 87 comes in between 64 and 128 so it should be active in that place so 1 at that place so to find it easier 64* 1 + 32 = 96 which is greater than 87 so no 32 64* 1 + 32*0 + 16 = 80 so yes 16 can be active 64*1 + 32*0 + 16*1 + 8 = 88 which is greater than 87 so it (8) should be inactive 64*1+32*0+16*1+8*0+ 4 = 84 so it (4) can be active 64*1+32*0+16*1+8*0+4*1+2= 86 so it(2) can be active 64*1 + 32*0+16*1+8*0+4*1+2*1+1=87 so it(1) can be active so so the answer is 1010111 thank you!
