a)

Wykonajmy najpierw dzielenie pisemne:

$\begin{array}{l}\underline{231}\\ 462:2\\ \underline{-4}\\ 06\\ \underline{-6}\\ 02\\ \underline{-2}\\ 0\end{array}\begin{array}{l}\underline{111}\\ 555:5\\ \underline{-5}\\ 05\\ \underline{-5}\\ 05\\ \underline{-5}\\ 0\end{array}\begin{array}{l}\underline{321}\\ 963:3\\ \underline{-9}\\ 06\\ \underline{-6}\\ 03\\ \underline{-3}\\ 0\end{array}$

Sprawdźmy działania:

$\begin{array}{r}231\\ \underline{\cdot 2}\\ 462\end{array}\begin{array}{r}111\\ \underline{\cdot 5}\\ 555\end{array}\begin{array}{r}321\\ \underline{\cdot 3}\\ 963\end{array}$

b)

Wykonajmy najpierw dzielenie pisemne:

$\begin{array}{l}\underline{158}\\ 948:6\\ \underline{-6}\\ 34\\ \underline{-30}\\ 48\\ \underline{-48}\\ 0\end{array}\begin{array}{l}\underline{82}\\ 574:7\\ \underline{-56}\\ 14\\ \underline{-14}\\ 0\\ \\ \end{array}\begin{array}{l}\underline{82}\\ 656:8\\ \underline{-64}\\ 16\\ \underline{-16}\\ 0\\ \\ \end{array}$

Sprawdźmy działania:

$\begin{array}{r}\stackrel{3}{1}\stackrel{4}{5}8\\ \underline{\cdot 6}\\ 948\end{array}\begin{array}{r}\stackrel{1}{8}2\\ \underline{\cdot 7}\\ 574\end{array}\begin{array}{r}\stackrel{1}{8}2\\ \underline{\cdot 8}\\ 656\end{array}$
