To convert the binary number $10110011010$ to octal, follow these steps:

1. Group the binary digits into groups of 3, starting from the right. If the leftmost group has fewer than 3 digits, pad it with zeros.

   $10110011010 \rightarrow 010 110 011 010$

2. Convert each group of 3 binary digits to its octal equivalent:

   • $010_2 = 2_8$
   • $110_2 = 6_8$
   • $011_2 = 3_8$
   • $010_2 = 2_8$

3. Write the octal equivalent by combining the results:

   The octal representation of $10110011010_2$ is $2632_8$.
