Your code does not work because
1) you collect all div-elements and
2) elementsByTagName[num].OuterHtml.Contains("URaP8 Kf Pf b-K b-K-Xb") can match with multiple div-elements

Some solutions could be
1) If HTML-element has an id-attribute, use that because it is unique in your web-page:
HtmlElement textBox = this.WebBrowser1.Document.GetElementById("Id for this element");

2) If the element has a name-attribute, try to use it:
if (elementsByTagName[num].Name == "Name of this element")

3) Instead of collection all the div-elements, try to narrow your search. For example, if your textbox is an input-element then get only page's input-tags:
HtmlElementCollection elementsByTagName = this.WebBrowser1.Document.Body.GetElementsByTagName("input");
and narrow results further with element's attributes:
if (elementsByTagName[num].GetAttribute("type") == "text")
Now you would get all the HTML-elements similar to <input type="text"></input>
