Để tính \(349459 \div 56\), ta thực hiện phép chia như sau:

\[ \require{enclose}
\begin{array}{r|l}
56 & 349459 \\
\enclose{downdiagonalstrike}{56} & \enclose{downdiagonalstrike}{6229} \\
\hline
\enclose{downdiagonalstrike}{289} & \enclose{downdiagonalstrike}{54} \\
\enclose{downdiagonalstrike}{280} \\
\hline
\enclose{downdiagonalstrike}{945} & \enclose{downdiagonalstrike}{16} \\
\enclose{downdiagonalstrike}{896} \\
\hline
\enclose{downdiagonalstrike}{490} & \enclose{downdiagonalstrike}{8} \\
\enclose{downdiagonalstrike}{448} \\
\hline
42 & 1 \\
\end{array}
\]

Kết quả là \(349459 \div 56 = 6233\) (phần nguyên), dư \(1\).
