1. The problem asks to convert the scientific notation $6.29 \times 10^6$ into an ordinary number. 2. Scientific notation expresses numbers as a product of a number between 1 and 10 and a power of 10. 3. The power of 10, $10^6$, means we multiply by 1 followed by 6 zeros. 4. To convert $6.29 \times 10^6$, move the decimal point in 6.29 six places to the right. 5. Moving the decimal 6 places right: $6.29 \to 6290000$ (adding zeros as needed). 6. Therefore, $6.29 \times 10^6 = 6290000$. 7. So, Summer takes 6290000 steps in a year written as an ordinary number.
