So, for the next event, we will find the new divine in HoPs? How many HoPs you would need in order to get the divine?

The divine is also available in HOP's. After 15 tries, it is offered to you in the reserved sales for 20 passes, and with each new HOP you open, the price decreases down to 5 passes. So if you open 16 HOPs, the divine will be 19 passes.

Without using the reserved sales it took me 52 passes to get the divine

I don't know if anyone's done this yet, but the Derby is basically an arcade game where you have four horses lined up to race to set off a light at the far end. You pay your fee, pick a horse, and then click a button to throw a ball at numbered slots. Number of the slot = number of steps your horse gets to advance. (The other three horses racing beside you are automated.)
Depending on your placement for setting off the light (first/second/third/fourth), you get a certain number of flags. As far as I can tell, it's 15 for first, 14 for second, and 13 for third, so you could guess that it's 12 for fourth. (Anyone care to confirm?)
With the flags you earn from the race, you can buy prizes, which I think will be appreciated -> you can pick your own prizes from a list.

Regarding bonus coins: (@Spyder)
Bonus items block off the hole with the lowest value on the board. So, the first you use blocks off the 3, then the 4, and up, to a max of 5 used per ball throw, where you would definitely get a 6. However, on the next throw all holes are unblocked again, which seems unreasonable - we'd need 50+ bonus coins to guarantee a 6 on every throw.
They don't seem very important to me. I've done three races; got third on the first and third ones, with no bonus items, and got 13 flags from both, then got first on the second one, using 6 bonus items, and got 15 flags - but that's only a difference of 2 flags. Over the span of the three races I only got my ball into the "3" slot thrice, and seemed to get "5" the most.

Flag amount required triples every time you cash in for a prize.

Say hello to Caryopsis.
"Caryopsis is one of the Plant Kingdom horses.
She can be watered instead of drinking.
This horse's skills increase when you give them Droppings. The skills increase depends on the amount of Droppings the horse is given, as well as the season in the game.
When she reaches 80 skill points, she can be pruned. Her skills will then be reset to 0, but she'll give you 1 x Pass seeds!
This mare cannot be sold."

There is also a promo on preprod where you can grab her from the HoPs - not sure when/whether that's coming here, but it took me 20 HoPs to get her. After 15 I was given the option to buy her from reserved sales for 20 passes, with the price dropping one pass with every next HoP I used. c: Additionally, she comes with 80 skill points, so your first pass seed is given as soon as you get her.
