How to convert a long string into desired length variables or cells?

i have a string that contains 256000 character. Actually it has hexadecimal numbers like "ea3672f1a90....."

I would like to convert this string into a variable like 256000x1 double (every number in a cell) or maybe every 8 number in a cell like 32000x1 variable.

How can i do that i tried so many codes but couldnt achieved success.

S = "ea3672f1a9012345";
V1 = sscanf(S,'%1x')

V1 = 16×1

14 10 3 6 7 2 15 1 10 9

V2 = sscanf(S,'%8x')

V2 = 2×1
