The tag used to create a division in a webpage is the `<div>` tag. This tag serves as a block-level element that is designed to group together other HTML elements, which allows for better structure and styling of a webpage. Using `<div>` improves the organization of content, enables the application of CSS styles to multiple elements at once, and helps in creating layouts.

Block-level elements like `<div>` take up the full width available, meaning they start on a new line and stack vertically in the layout. This feature is particularly useful for dividing sections of a webpage into logical groups, such as headers, footers, sidebars, and main content areas.

The other choices do not fulfill the same purpose. The `<span>` tag is an inline element primarily used for styling specific parts of text or grouping inline-elements, not for creating divisions. The `<section>` tag is semantic, meant for defining sections of content that share a common theme, but it does not replace the more general-purpose `<div>`. The `<group>` tag is not a standard HTML tag and does not serve any function in HTML.
