The problem provided is to divide \( \frac{6}{5 - i} \) and express the result in standard form (which is the form \( a + bi \), where \( a \) and \( b \) are real numbers).

### Step-by-Step Solution:
1. To divide by a complex number, multiply both the numerator and denominator by the **conjugate** of the denominator. The conjugate of \( 5 - i \) is \( 5 + i \).

2. Multiply the numerator and the denominator by \( 5 + i \):

\[
\frac{6}{5 - i} \times \frac{5 + i}{5 + i} = \frac{6(5 + i)}{(5 - i)(5 + i)}
\]

3. Simplify the denominator using the difference of squares formula:
\[
(5 - i)(5 + i) = 5^2 - i^2 = 25 - (-1) = 25 + 1 = 26
\]

4. Now, multiply the numerator:
\[
6(5 + i) = 30 + 6i
\]

5. Therefore, the expression becomes:
\[
\frac{30 + 6i}{26} = \frac{30}{26} + \frac{6i}{26} = \frac{15}{13} + \frac{3i}{13}
\]

### Final Answer:
The result in standard form is:
\[
\frac{15}{13} + \frac{3i}{13}
\]
