The image shows the step-by-step process of dividing 17.2 by 0.2:

1. Start with $17.2 \div 0.2$.
2. Multiply both the numerator (17.2) and the denominator (0.2) by 10 to eliminate the decimal in the denominator.
3. The numerator becomes $172$, and the denominator becomes $2$.
4. Now, divide $172 \div 2$, which equals $86$.

Let me know if you'd like more details or further clarification.

Relative Questions:

1. How does multiplying by 10 help in division?
2. What if the denominator was $0.5$ instead of $0.2$?
3. Can you explain why the decimal places are handled this way?
4. How would this division look if you expressed 17.2 as a fraction?
5. Is there an alternative way to approach this calculation without multiplying by 10?

Tip: When dividing by a decimal, it's often easier to eliminate the decimal by multiplying both numbers by powers of 10.
