My story "Damsel in the Red Dress" is separated into books. Each book could be considered an arch with two-four mini arcs inside of them, and those are just separated into chapters. because the arcs tend to all be foreshadowed in strung into each other, so the only thing that could be considered an arc are the umbrella of a time frame the events take place in sort of like.
Book one: Starts with the award show and leads to the climax of her doing a speech at the opening of her exhibit in a museum. The overall arc is the process of her becoming a crazy famous artist, from the first moment she got major recognition to the moment she became someone who took over the internet.
