Base 10 to Binary: Right-to-Left

Keep dividing by the base until zero; write all the remainder digits down from right-to-left:

1933 base 10 to binary (base 2):

1933 div 2 = 966 rem 1

966 div 2 = 483 rem 0
483 div 2 = 241 rem 1
241 div 2 = 120 rem 1
120 div 2 = 60 rem 0
60 div 2 = 30 rem 0
30 div 2 = 15 rem 0
15 div 2 = 7 rem 1
7 div 2 = 3 rem 1
3 div 2 = 1 rem 1
1 div 2 = 0 rem 1
