The number is seventy-nine million, fifty thousand (79,050,000), so the five is in the ten-thousands place because it is part of the word "fifty." The 7 is in the ten-millions place, the 9 in the millions place, the first 0 in the hundred thousands place, the five in the ten-thousands place, and the next 0 in the hundreds place.
