25 ÷ 425
you have your dividend and the divisor
for example: The divisor is the number you use to divde(25) the other number and the dividend is the number you going to divide.
To start you look at the first number of the dividend (4) we want to divide 4 by 25. How many times does four go into 25? 0 times

25|425
now you multiply 25 x 0 that equals 0

next you subtract 4-0 and you will get 4

42
you place the 4 under the 4 and 0 like so. You bring down the number 2 now.
Now you have to divide 42 by 25 ( 42 ÷ 25) and you will get 1 and 17 remainder. ( ignore the remainders at this point) Place the 1 at the top of the

Now you want to divide 175 ÷25 = 7 and zero remainder.

Next multiply 7 x 25 = 175 place 175 under the 175 and subtract 175-175= 000.
Therefore the answer must be 17 or if you want to be technical...017. :)
I hope this helps...
