How did Toyota use the approach?
The PDCA cycle is one of the main elements of the Toyota Just-in-Time Production System. Over the past 20 years, these technologies have become almost the main example of lean manufacturing using PDCA. For more information on the application of Toyota PDCA in lean manufacturing, read the book The Toyota Method by Jeffrey Lake (2003). According to Edward Deming, the PDCA methodology can be used to:

Continuous quality improvement.

Reduction in the number of defects due to more uniform characteristics.

Understanding the meaning of quality.

How to use in a large company?
The hierarchy of the PDCA cycle when working with a large organization looks like this:

The small ring is inside the large one. If a company operates as a single PDCA cycle, each department, group, or mini-cycle fits into it, creating a PDCA hierarchy.

Constant improvement of the PDCA cycle. It does not freeze at one level, each of its elements solves part of the problems, allows achieving part of the results, works longer, corresponds to the level of one step. The next cycle acquires new goals and opportunities, which contributes to the continued growth of the business.

However, for many businesses, the Deming Cycle is a great way to slowly perfect a product, maintain good quality, and stay ahead of competitors.
