Each step will be shown below. A division box shows 4 on the left, and 683 inside.

 In the division box, now 400 is below 683, with difference of 283. Think ''$4$ goes into $600$ how many times?''
At least $100$ times, but not more than $200$.

In the division box, now 280 is below 283, with difference of 3.  Think ''$4$ goes into $280$ how many times?''
Exactly $70$ times. 
Think ''$4$ goes into $3$ how many times?''
Exactly $0.75$ times.
