We have to group 7 bits for each group. i.e., from least significant position to most significant position and then place them with equivalent ASCII code.

Most of the people asking why to take 7bits particularly. The explanation is simple.
A-Z = 65-90
a-z = 97 - 122
2^0 = 1
2^1 = 2
2^2 s= 4
.
.
.
2^6 = 64
2^7 = 128
2^8 = 256
Here all the alphabets including upper and lower decimal values will not exceed 128 which is 2^7, which means the MSB is always 0 which is ignored here.
