Like this?
test = RandomInteger[{0, 10}, 10]
{5, 9, 9, 2, 0, 4, 10, 4, 5, 4}
NestList[Rest[# - #[[1]]] &, test, 9]
{{5, 9, 9, 2, 0, 4, 10, 4, 5, 4}, {4, 4, -3, -5, -1, 5, -1,
0, -1}, {0, -7, -9, -5, 1, -5, -4, -5}, {-7, -9, -5,
1, -5, -4, -5}, {-2, 2, 8, 2, 3, 2}, {4, 10, 4, 5, 4}, {6, 0, 1,
0}, {-6, -5, -6}, {1, 0}, {-1}}
