In the partial solution described in the original post, you can improve the solution if change the following code

private float calculateProgression(WebView content) {
    float contentHeight = content.getContentHeight();
    float currentScrollPosition = content.getScrollY();
    float percentWebview = currentScrollPosition/ contentHeight;
    return percentWebview;
}

due to the top position of the component, when you are using content.getTop () is not necessary; So what it does is add to the actual position of the scroll Y position where the component is located with respect to it parent and runs down the content. I hope my explanation is clear.
