There is a parallel account recorded in
1 Chronicles 15:25 So David and the elders of Israel and the commanders of units of a thousand went to bring up the ark of the covenant of the Lord from the house of Obed-Edom, with rejoicing. 26 Because God had helped the Levites who were carrying the ark of the covenant of the Lord, seven bulls and seven rams were sacrificed.
That seem to be the summary of sacrifices.
More sacrifices were performed at the destination, in
1 Chronicles 16:1
They brought the ark of God and set it inside the tent that David had pitched for it, and they presented burnt offerings and fellowship offerings before God.
Sacrificing after six every steps all the way to Zion practically is not likely.
