Answer
Fill the blanks with
$3, \quad 4$
Work Step by Step
When we divide numbers, $\quad $(Dividend)$\div$(Divisor)
and obtain a Quotient and Remainder.
we check the result by
$(Dividend)\stackrel{?}{=}(Quotient)\times(Divisor)+(Remainder)$
So, we check this division, where
Dividend = $19,$
Divisor = $5,$
Quotient = $3$
Remainder = $4$
with
$19\stackrel{?}{=}5\cdot 3+4$
$\quad=15+4=19\quad $... (ok)
Fill the blanks with
$3, \quad 4$
