What does partitioning mean?
Partitioning is the deliberate division of a larger whole into smaller, distinct parts. The process may be physical, as when a disk is divided into partitions, or conceptual, as when researchers partition a sample into groups for analysis. Partitioning can also refer to the resulting structure or to the method used to create it. Its connotation is generally orderly and systematic rather than arbitrary: the parts are usually separated for a practical purpose, such as storage, classification, distribution, or comparison. The term is especially frequent in computing, but it also appears in mathematics, music, business, and academic writing. In everyday speech, “division” is more usual, whereas “partitioning” is favored when the precise arrangement of separate parts is important. Understanding the word can therefore help distinguish not merely separating something, but organizing it into a purposeful system.
The process of dividing something into separate parts, or the resulting arrangement of those parts.
"The partitioning of the data revealed clear differences between the two groups."
The plural “partitionings” is possible but uncommon; pluralization is normally avoided by using constructions such as “the act of partitioning” or “different partitionings of the market.”
Denoting a process, method, or structure that divides something into separate parts.
"The operating system uses a partitioning scheme to organize the available memory."
This is an attributive participial use and is especially common in technical writing.
Rare; the noun is normally used in the singular or as a mass noun.
"The study compared several different partitionings of the market."
Partitioning turns one whole into purposeful parts, whether the subject is a disk, a market, or a musical score.

Where does partitioning come from?
Partitioning was formed in the 19th century by adding the suffix “-ing” to “partition.” “Partition” came through French from Latin partitio, a division, derived from partire, “to divide,” and ultimately from Latin pars, meaning “part.” The same root also produced words such as “portion,” “part,” and “partner,” reflecting the broad sense of dividing or sharing a whole.

How partitioning is actually used
The word is especially common in computing, mathematics, and organizational contexts. It is more technical than the general word “division” and often suggests a deliberate or systematic arrangement.
