Puts the remainder of division by 1000 (i.e. the three last digits of the
number) in m_mod.

Remainder of division by 500 (i.e. the three last digits or if that number
would be higher than 500, the three last digits minus 500)

2 last digits.

2 last digits minus 50 if necessary.

Last digit.

Last digit minus 5 if necessary.

Divides the number by 1000, cutting of everything after the point (because
this is integer division). So basically this returns everything but the
three last digits.

>   d_div = m_mod/500

This is one if the third to last digit (i.e. the one who specifies the
hundreds) is 5 or higher and zero otherwise.

>   c_div = d_mod/100

The third to last digit minus 5 if it's 5 or higher.

The same thing for the second to last and last digit accordingly.

I hope this is what I just did and you understand it now.
