If you look at the mixed fraction 52 5/15, you'll see that the numerator is the same as the remainder (5), the denominator is our original divisor (15), and the whole number is our final answer (52).

So far, polyunsaturated fatty acids and their biologically active derivatives have been shown to regulate cell survival, neurogenesis, brain inflammation and synaptic function. Rao, J. S. et al. n-3 polyunsaturated fatty acid deprivation in rats decreases frontal cortex BDNF via a p38 MAPK-dependent mechanism. Mol. Psychiatry 12, 36–46 (2007). Though some were sold to civilians postwar, to be used as ferries and trawlers, 1 was retained by the German Navy and received periodic upgrades before being scrapped. The remaining vessels went to the British and Americans as war plunder and were scrapped soon after.

The M-802 is also equipped with depth charges as a supplicant to its torpedo armament. 4 WBG depth charges with 100 kg of TNT apiece are mounted on launchers to either side of the rear 37 mm, with 2 firing to each side. Their high weight means they land relatively close to the vessel, meaning they are only effective at destroying torpedoes approaching amidships or PT boats making close runs against the side of the vessel.

Biochemistry 52, 7254–7261 (2013). The M-17 is similar to the M-802 but without the reinforced engine armour or the torpedoes. As with most sub-chasers, it's slow and won't arrive first to the battlefield, but the ship has well armoured 105 mm main guns with enough fire power to hull break many ships or pen destroyers with base fuze HE in desperate scenarios. Facing destroyers is ill-advised as they have higher caliber guns in larger quantity. Larrieu, T. et al. Hypothalamo-pituitary-adrenal axis mediates n-3 polyunsaturated fatty acids deficient-diet induced depressive- and anxiety-like symptoms along with neuronal atrophy. Transl.

Now you've learned the long division approach to 15 divided by 785, here are a few other ways you might do the calculation: Coastal fleet spawn means can get into combat with smaller vessels faster than previous spawn location.
