There are different ways to practice math specially division.

First you need to know the exact meaning of division. Division also means repeated subtraction. Let me explain with an example

56/5

56-5=51-5=46-5=41-5=36-5=31-5=26-5=21-5=16-5=11-5=6-5=1

quotient is number of times 5 subtracted i.e, 11 and remainder is 1

another way is long division method. This also be done by subtracting in tens or hundreds.

Lets take the same example 56/5

56 - (10 times 5, 50) = 6 - (1 time 5, 5) = 1` `

Quotient is 10+1 = 11 and remainder is 1.

One more example 468/ 13

468 - (10 times 13, 130) = 338 - (10 times 13, 130) = 208 -(10 times 13, 130) = 78 - (6 times 13,78) = 0

quotient is 10+10+10+6 = 36, remainder 0.
