Step 1 of 4 · The rule
A number is divisible by 4 if its last two digits form a number divisible by 4.
N ÷ 4 works ⇔ (last 2 digits) ÷ 4 works.
Why? 100 is divisible by 4 (100 = 4 × 25). So everything from the hundreds place up is automatically ÷ 4 — only the last two digits decide.

Is 1248 divisible by 4?
Ignore the leading digits — only check the last two.
Last two digits: 48
48 ÷ 4 = 12 ✓ (exact)
YES — 1248 is divisible by 4
Step 3 of 4 · Worked: 2 2 5 0
Is 2250 divisible by 4?
Same approach.
Last two digits: 50
50 ÷ 4 = 12 remainder 2 ✗
NO — 2250 is NOT divisible by 4
