Выполним вычисления по порядку.

$$518 \cdot 204$$

$$518 \cdot 4 = 2072$$
$$518 \cdot 200 = 103600$$
$$2072 + 103600 = 105672$$

$$518 \cdot 204 = 105672$$

$$766 \cdot 530$$

$$766 \cdot 5 = 3830$$
$$766 \cdot 500 = 383000$$
$$383000 + 3830 = 405980$$

$$766 \cdot 530 = 405980$$

$$283410 : 603$$

$$283410 : 603 = 470$$
$$603 \cdot 470 = 283410$$

$$166520 : 724$$

$$166520 : 724 = 230$$
$$724 \cdot 230 = 166520$$

$$435 \cdot 87$$

$$435 \cdot 7 = 3045$$
$$435 \cdot 80 = 34800$$
$$3045 + 34800 = 37845$$

$$435 \cdot 87 = 37845$$

$$608 \cdot 95$$

$$608 \cdot 5 = 3040$$
$$608 \cdot 90 = 54720$$
$$3040 + 54720 = 57760$$

$$608 \cdot 95 = 57760$$

$$5476 : 37$$

$$5476 : 37 = 148$$
$$37 \cdot 148 = 5476$$

$$12098 : 46$$

$$12098 : 46 = 263$$
$$46 \cdot 263 = 12098$$
