To divide 10 years by 0.9, you follow the basic division rule:

\[
\frac{10 \, \text{years}}{0.9} = \frac{10}{0.9}
\]

To simplify this, you can multiply both the numerator and denominator by 10 to remove the decimal in the denominator:

\[
\frac{10}{0.9} = \frac{10 \times 10}{0.9 \times 10} = \frac{100}{9}
\]

Now, perform the division:

\[
\frac{100}{9} \approx 11.11 \, \text{years}
\]

So, dividing 10 years by 0.9 gives approximately **11.11 years**.
