Abstract: A container dividing system partitions a storage container to allow a user to separate the contents of the storage container during storage, transport, or freight. The container dividing system includes a storage container, a divider, a divider receiving base, and at least two divider-retaining mounts. The divider partitions a storage volume of the storage container into a plurality of storage volumes, which the contents can be discretely placed. The divider-receiving base secures the divider to a container base of the storage container. The at least two divider-retaining mounts secure the divider to a lateral wall of the storage container. The divider is positioned within the divider-receiving base and the at least two divider-retaining mounts.
