$\snippet{name: long_division, x: 995, y: 4}$
995 : 4 = 248 (ост.3)
 
Проверка:
248 * 4 + 3 = 992 + 3 = 995

$\snippet{name: long_division, x: 510, y: 21}$
510 : 21 = 24 (ост.6)
 
Проверка:
24 * 21 + 6 = 504 + 6 = 510
$\snippet{name: column_multiplication, x: 24, y: 21}$
 

$\snippet{name: long_division, x: 3964, y: 18}$
3964 : 18 = 220 (ост.4)
