Why are the numbers 500, 700 and 900 not linear with the other hundreds in Spanish?

British expats 'in tears' as Spain to deport 500 for failing to register for residency under post-Brexit regulations. By March 31 they will be deemed as illegal immigrants.
Nobody suspects Spanish deportation.

tl;dr:
Spanish extreme athlete, Beatriz Flamini, has emerged from a cave outside Granada, after living 70 meters deep for 500 days with no contact with the outside world. Flamini, who is an elite sportswoman and mountaineer, is said to have broken a world record for the longest time spent in a cave. Her experiment was closely monitored by scientists seeking to learn more about the capacities of the human mind and circadian rhythms. Flamini spent her time underground doing exercises, painting and drawing, and knitting woolly hats. She took two GoPro cameras to document her time, and got through 60 books and 1,000 liters of water, according to her support team.
Flamini was monitored by a group of psychologists, researchers, speleologists — specialists in the study of caves — and physical trainers who watched her every move and monitored her physical and mental well-being. According to Spanish news agency EFE, her experience is being studied by scientists at the universities of Granada and Almeria and a Madrid-based sleep clinic to determine the impact of social isolation and extreme temporary disorientation on people's perception of time, the possible neuropsychological and cognitive changes humans undergo underground, and the impact on circadian rhythms and sleep.
