SQL SERVER order by random in series

I want to display records in random order, the simplest answer is order by NEWID(), that's fine.

I have EmployeesID from 1 to 100. The output needs to be displayed in random series, i.e.

30.31.32.33...40..20.21.22..30..80.81.82..90.1.2.3..10..and so on..

If there are 100 records, it should be divided into 10 parts and every part displays randomly.

CODE I tried is:

select empId,empName from employees
where empID between 1 and 100
order by NEWID()


INPUT
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100
OUTPUT
50 51 52 53 54 55 56 57 58 59 60 90 91 92 93 94 95 96 97 98 99 100 30 31 32 33 34 35 36 37 38 39 40 10 11 12 13 14 15 16 17 18 19 20 20 21 22 23 24 25 26 27 28 29 30 70 71 72 73 74 75 76 77 78 79 80 60 61 62 63 64 65 66 67 68 69 70 1 2 3 4 5 6 7 8 9 10 40 41 42 43 44 45 46 47 48 49 50 80 81 82 83 84 85 86 87 88 89 90
