How it works
These division mental math drills go from the facts for 2, 5 and 10 to four digits divided by a digit. Every question is built as divisor times answer, so nothing leaves a remainder.

Facts first
The warm-up mixes the facts for 2, 3, 4, 5, 6 and 10, with answers from 2 to 12. How many 7s, 8s and 9s and How many 11s and 12s finish the tables; the Drill menu is under More options.
Halving and tens
Dividing by 8 is three halvings: 336 ÷ 8 goes 168, 84, 42. Dividing by 20 drops a zero and halves. Dividing by 25 counts four to every hundred, and by 50 two.
Bigger divisions
Split off a piece the divisor fits: 4,872 ÷ 6 is 4,800 ÷ 6 = 800 and 72 ÷ 6 = 12, so 812.
Questions and answers
How do you do division in your head?
Break the number into pieces the divisor fits. For 72 ÷ 3, take 60 ÷ 3 = 20 and 12 ÷ 3 = 4, so 24. For an even divisor, halve first: 54 ÷ 6 is 27 ÷ 3 = 9.
Do any questions have remainders?
No. Each question is made by multiplying the divisor by a whole answer, so every division comes out exactly. The number pad has no decimal point.
Are these division mental math games?
They are timed drills with a score to beat: your own best for each drill and run length. There are no levels to unlock, no lives and no characters.
Where are the drills on dividing bigger numbers by 4 and by 5?
On mental math practice, under Division: Divide by 4 and Divide by 5 go past the tables, beside Halve a three-digit number and Three digits divided by one digit. Here 4 and 5 are in the fact drills.
