To find the modulus of 271875 with respect to 9, we can follow these steps:

1. Sum the digits of the number:
   $2 + 7 + 1 + 8 + 7 + 5 = 30$

2. Sum the digits of the result if necessary:
   $3 + 0 = 3$

3. Find the modulus:
   Since the sum of the digits is 3, the remainder when 271875 is divided by 9 is 3.

Thus, $271875 \mod 9 = 3$.
