Fourth grade division rests almost entirely on multiplication recall. The standard's mention of the relationship between multiplication and division is not decoration — it is the method. A student who knows that 8 × 90 is 720 gets through 784 ÷ 8 quickly; a student who does not will be slow no matter how well they have learned the long-division layout.
Quoted verbatim from the Common Core State Standards for Mathematics. Nothing here is paraphrased.
