Well, darling, if we're talking about good ol' 21, it can go into 189 a total of 9 times. It's simple math, honey, just divide 189 by 21 and you'll get your answer. Math doesn't have to be a headache, sugar, just let those numbers do their thing.
196/9 = 21/77... recurring.
Oh, dude, 9 and 21 both go into numbers that are multiples of both 9 and 21. So, like, they can go into numbers like 63, 126, 189, and so on. It's just basic math, nothing too mind-blowing.
4 x 21 = 84 with a remainder of 9
1 and 3.
63 and its multiples
To find out how many times 9 goes into 189, you divide 189 by 9. The result is 21, which means that 9 goes into 189 21 times without any remainder. This is because 9 multiplied by 21 equals 189.
Twice with a remainder of three
21 with remainder 5.
