How to correctly convert blockchain api amount?

Question

PHP

Shalom everyone!
Forgive me in advance for a possibly stupid question (I’m not particularly good at math)

When requesting a blockchain api ( https://blockchain.info/rawaddr/16JXPyqRCTZbpBViwG... )
The number of bitcoins that came is 3403691 how to convert it to this format
0.03403691 PHP but you can just paint it like a first-grader in mathematical operations
Thanks in advance!

<?php
$a=3403691;
