Since we are dividing by b, the remainder d can be expressed fractionally as d/b. Thus, we have:
a/b = c + d/b
a = bc + d
a - bc = d

There's a nice rule that says, "If N divided by D equals Q with remainder R, then N = DQ + R"BTGmoderatorLU wrote: ↑Sat Jun 27, 2020 2:51 pmSource: Manhattan Prep

For example, since 17 divided by 5 equals 3 with remainder 2, then we can write 17 = (5)(3) + 2
Likewise, since 53 divided by 10 equals 5 with remainder 3, then we can write 53 = (10)(5) + 3
GIVEN: When a is divided by b, the quotient is c and the remainder is d.
We can write: a =cb + d
Subtract cb from both sides of the equation to get: a - cb = d
