Render a div on the right and keep the nav centered - html

Question

I would like to render a nav and a div containing several buttons on the same "line" by getting the nav centered. However, I can not get a satisfying result. If I put my div after the nav, the div is displayed on the right side but under the nav, in part due to the following CSS statements:
header {
position: relative;
width: 100%
background: #333;
}
nav {
position: relative;
margin: 0 auto;
}
If I remove the header width attribute and make the nav float to the left, then I lose the centered position of my nav.
Here is the HTML code:
<div class='header'>
<div class='header-content'>
<div class='welcome-div'>
<h1>
Hello
</h1>
<header>
<nav id='drop-down-menu'>
<div class="button"></div>
<ul>
<li class='active'><a href='#'>HOME</a></li>
<li><a href='#'>ABOUT</a></li>
<li><a href='#'>PRODUCTS</a>
<ul>
<li><a href='#'>Product 1</a>
<ul>
<li><a href='#'>Sub Product</a></li>
<li><a href='#'>Sub Product</a></li>
</ul>
</li>
<li><a href='#'>Product 2</a>
<ul>
<li><a href='#'>Sub Product</a></li>
<li><a href='#'>Sub Product</a></li>
</ul>
</li>
</ul>
</li>
<li><a href='#'>BIO</a></li>
<li><a href='#'>VIDEO</a></li>
<li><a href='#'>GALLERY</a></li>
<li><a href='#'>CONTACT</a></li>
</ul>
</nav>
<div class='lang'>
<a class='hover-fade'>Français</a>
<a class='hover-fade'>English</a>
<a class='hover-fade'>日本語</a>
</div>
</header>
</div>
</div>
</div>
<div class='clear'/>
The CSS one:

}
.clear {
clear: both;
}
And a JSFiddle sample.
I would like to keep the same layout, but with the 3 buttons aligned with the nav.
Thanks for your answers.

Absolutely position your lang block in top right of header:
* {
margin: 0;
padding: 0;
text-decoration: none;
}
header {
position: relative;
width: 100%
background: #333;
}
nav {
position: relative;
margin: 0 auto;
}

#drop-down-menu ul,
