Multiple Split Lines

Each year I make a puzzle for my birthday (13 August) but the rules are chosen by couple of people and try to do something with those before my birthday is arrived. This is the puzzle I created hope you enjoy it.

Rules:

Normal sudoku rules apply. Blue dots divide lines into segments with equal sums (but this sum may be different for different lines). Furthermore for any two adjacent digits along the line, dividing one by the other gives an exact integer (one is a multiple of the other). Digits may repeat on a line and lines don't branch. Different lines don't share cells with each other. Additionally, the grid is partially covered in fog. Placing correct digits will clear the fog from surrounding cells, possibly revealing more clues.

Tricky opening, then smooth sailing

I actually found this one very approachable - maybe because I've been working with multiple lines a lot recently. Really liked the use of fog, and how the constraint combined with equal split logic. And in a rare turn of events, a Dorlir puzzle I could do without asking for any hints - lovely stuff!

That was very enjoyable but definitely a tricky one!
