Solve the short division problems with remainders.

11. $437 \div 19$

Step 1: Take first two digits $43$.
$19 \times 2 = 38$ (since $19 \times 3 = 57 > 43$)
$43 - 38 = 5$
Remainder $5$, carry down to next digit $7$.

Step 2: $5$ carried makes $57$.
$19 \times 3 = 57$
$57 - 57 = 0$
Remainder $0$.

Quotient reads $23$.
23 \ remainder \ 0

12. $436 \div 19$

Step 1: Take first two digits $43$.
$19 \times 2 = 38$ (since $19 \times 3 = 57 > 43$)
$43 - 38 = 5$
Remainder $5$, carry down to next digit $6$.

Step 2: $5$ carried makes $56$.
$19 \times 2 = 38$ (since $19 \times 3 = 57 > 56$)
$56 - 38 = 18$
Remainder $18$.

Quotient reads $22$.
22 \ remainder \ 18
