To find the percent of a number, you first convert the percent into its decimal form (in this case, 13.4 becomes 0.134) and multiply it by the number you want to find the percent of (in this case, 1,349,585,838)
$${\mathtt{0.134}}{\mathtt{\,\times\,}}{\mathtt{1\,349\,585\,838}} = {\mathtt{180\,844\,502.292}}$$
