To find the percentage of oil spilled that is caused by natural seepage, you can use the following formula for percentage:

\[ \text{Percentage} = \left( \frac{\text{Part}}{\text{Total}} \right) \times 100 \]

In this context:
- The part caused by natural seepage is 341 million gallons.
- The total amount of oil spilled is 800 million gallons.

Plug these values into the formula:

\[ \text{Percentage} = \left( \frac{341 \text{ million gallons}}{800 \text{ million gallons}} \right) \times 100 \]

Let's do the calculation step-by-step:

1. Divide 341 by 800:

\[ \frac{341}{800} = 0.42625 \]

2. Multiply the result by 100 to convert it to a percentage:

\[ 0.42625 \times 100 = 42.625\% \]

Therefore, approximately 42.625% of all oil spilled is caused by natural seepage.
