Here is something I came up with. You can copy-paste into Developer Tools-> Templates and play with it.
A bit shift to the right is achieved by dividing a number by 2**n where n is the number of bits to shift.

{% set num = 825307441 %}
{% set num1= (num/2**0) | int | bitwise_and(255) %}
{% set num2= (num/2**8) | int | bitwise_and(255) %}
{% set num3= (num/2**16) | int | bitwise_and(255) %}
{% set num4= (num/2**24) | int | bitwise_and(255) %}
{% set ToByte = num1, num2, num3, num4 %}
{{ ToByte[0], ToByte[1], ToByte[2], ToByte[3] }}
