Ill break it down for you so you can understand.
We use a method called "long division" to help us divide large numbers. But, if it does not go in, we need to make it into a decimal. Observe.
4 ⟌19
Four does not go into one. (Start with the first number then go right if it doesn't go in.) ((Also add a 0 up top)
0
4 ⟌19
4 does not go into 19 but it can go into 16. (Put a four at the top.)
04
4 ⟌19
-16
____
3
Now, if it can't go in, then put a point after the 4 and add a zero to the three.
04.75
4 ⟌19
-16
____ (4 x 7)
30 28

____
2 (0) (5 x 4)
20 20

Your answer is 04.75 OR 4.75.
