The first major success on the pitch occurred during the 1957–58 season when the club managed to reach the highest provincial level for the first time.

The local rivals quickly recovered, which resulted in fiercely contested derby matches for a number of seasons until 1977.

In that year, Deinze managed to obtain promotion while at the same time Sparta Petegem was relegated to the second provincial division and started struggling, even dropping to the third provincial level in 1986 and only narrowly avoiding yet another relegation the season thereafter.

The club started its climb to higher levels in 1993, winning promotion to the second provincial division, managed to move up to the highest provincial level where it remained nine seasons before finally reaching the national level of Belgian football for the first time in its history in 2008, moving into the Belgian Fourth Division.

Following a short return to the provincial leagues for the 2013–14 season, the club then managed to successive promotions to again reach its highest level ever, with the Belgian Third Division.
