   The number is 7,08,30,529. Let's identify the place value of each digit: 7 is in the crores place (70,000,000). 0 is in the ten lakhs place (0). 8 is in the lakhs place (8,00,000). 3 is in the ten thousands place (30,000). 0 is in the thousands place (0). 5 is in the hundreds place (500). 2 is in the tens place (20). 9 is in the ones place (9). The digit 8 is in the lakhs place, so its place value representation is 8,00,000, which is 8 million.
