Выполним вычисления:

1. $$\begin{array}{r}521600 \\ \underline{48}\phantom{0000}} \\ 41 \\ \underline{40} \\ 16 \\ \underline{16} \\ 0 \\ \underline{0} \\ 0 \\ \underline{0} \\ 0 \\ 0\end{array} | \begin{array}{l}8 \\ 65200\end{array}$$ $$521600 : 8 = 65200$$
2. $$\begin{array}{r}102018 \\ \underline{6}\phantom{000}} \\ 42 \\ \underline{42} \\ 0 \\ \underline{0} \\ 1 \\ \underline{0} \\ 18 \\ 18\end{array} | \begin{array}{l}6 \\ 17003\end{array}$$ $$102018 : 6 = 17003$$
3. $$2907 \cdot 3 \cdot 10 + 5403 = 8721 \cdot 10 + 5403 = 87210 + 5403 = 92613$$
4. $$780 \cdot 5 \cdot 100 – 20 471 = 3900 \cdot 100 - 20471 = 390000 - 20471 = 369529$$
