Найдите частное при делении многочлена \(\displaystyle -77z^{\,11}+49z^{\,7}-7z^{\,5}\) на одночлен \(\displaystyle 7z^{\,3}\) в столбик, при известном процессе деления:

\(\displaystyle -\)	\(\displaystyle \small\color{blue}{\bf -77z^{\,11}}\)	\(\displaystyle +\)	\(\displaystyle \small 49z^{\,7}\)	\(\displaystyle -\)	\(\displaystyle \small 7z^{\,5}\)	\(\displaystyle \small 7z^{\,3}\)
	\(\displaystyle \small -77z^{\,11}\)					[ ]	[ ]	[ ]
		\(\displaystyle -\)	\(\displaystyle \small\color{yellowgreen}{\bf 49z^{\,7}}\)	\(\displaystyle -\)	\(\displaystyle \small 7z^{\,5}\)
			\(\displaystyle \small 49z^{\,7}\)
				\(\displaystyle -\)	\(\displaystyle \small\color{orange}{\bf -7z^{\,5}}\)
					\(\displaystyle \small -7z^{\,5}\)
					\(\displaystyle \small0\)

С учетом найденного частного запишите разложение на множители:

\(\displaystyle -77z^{\,11}+49z^{\,7}-7z^{\,5}=7z^{\, 3}\cdot\big(\)[ ]\(\displaystyle \big){\small . }\)
