Knit pattern help

I am knitting my first sweater and I am having some trouble understanding the pattern. Can an experienced knitter please help me?
This is the part I am currently stuck on.
Shape sleeves
Cast on 5(6:7:8:9) sts at beg of next 8 rows. 88(100:112:124:136) sts. Work a further 18(22:24:26:28) rows. Divide for fronts
They told me to transfer to a circular needle so I did. Am I suppose to knit it together now? And what does divide for fronts mean?
Here is the whole pattern for reference.

Hello, and welcome. Before answering your question could I ask you to edit down the patern for copyright reasons?

It you take out everything from MATERIALS, to ABBREVIATIONS inclusive and FRONT EDGING to the end that will be a start.

No, you dont need to knit it together. The pattern still refering to rows and not rounds is the clue to this.

Divide for fronts isn’t an instruction but a ‘Chapter heading’, so follow the instructions that start
Next row K36(41:47:52:58) sts, leave these sts on a spare needle,…and you will be dividing for fronts.

Thank you so much. I edit it like you suggested and your help is very much appreciated. I will probably have more question as I continue with this pattern so thank you again.

Thanks for editing the pattern, it stops anyone getting into trouble, and I’m happy to be of help. If you have any further questions feel free to post them on this thread, and someone will answer.
