Two things to keep in mind regarding numbering across multiple frames: First, you have to set up a List, as discussed in this post. Second, fi you have more than one unthreaded text frame on the same page, the numbering can get wonky because the numbering is based on the order you created the text frames. Cut and paste a frame and the number updates.
When you are ready to restart numbering, you can use the technique above, or you can place your cursor inside a numbered paragraph above, click the Format Painter (the paintbrush icon on the Home tab under Clipboard), then click on the line where you want to restart numbering. Using Format Painter this way solves several paragraph numbering problems (the number sequence, indents, and inter-paragraph spacing) simultaneously.
One of the harder things to do in Adobe InDesign, surprisingly for a page layout tool, is to create multilevel or outline format numbered lists. The right way to accomplish this, according to the folks at Adobe, is to create a Style for every level of the list you’d like to have! Here are Adobe’s instructions on how to do so (This content is taken directly from https://helpx.adobe.com/indesign/using/bullets-numbering.html#create_multi_level_lists):
With the numbered paragraphs shown above, there is no extra spacing between the paragraphs. That’s easy to fix. Go ahead and type out at least part of your first numbered paragraph, then go to the Page Layout tab and adjust the value of Spacing After in the Paragraph section. Still no extra space? There’s one more setting to check. Click the launcher arrow in the lower right-hand corner to go to the Paragraph dialog box, uncheck the box next to “Don’t add space between paragraphs of the same style.” Click OK. That paragraph and all the remaining numbered ones will have more breathing room.

One solution is to format the heading with the style and follow it with a hidden paragraph mark. You should format the text in the next paragraph with a style that is not included in the Table of Contents. A hidden paragraph mark keeps the text together on one line when it is printed, even though it is actually two separate paragraphs. The Table of Contents command picks up only those paragraphs with heading styles and places them into the Table of Contents.
Place the insertion point in the paragraph and choose Restart Numbering from the context menu or choose Type > Bulleted And Numbered Lists > Restart Numbering. In normal lists, this command assigns the number 1 (or letter A) to a paragraph and makes it the first paragraph in a list. In multi-level lists, this command assigns the first lower-level number to a nested paragraph.
