Let's use an area model to find the answer to $133\div7$133÷7.
a
We set up the area model using a rectangle like this.
| $7$7 | |
| Total area: $133$133 |
Now if we don't know straight away what $133\div7$133÷7 is, we start with something we do know, like groups of $10$10.
Fill in the area used so far if we take out $10$10 groups of $7$7.
| $10$10 | ||
| $7$7 | $\editable{}$ | |
| Total area: $133$133 | ||
b
How much area is remaining?
| $10$10 | ||
| $7$7 | $70$70 | $\editable{}$ |
| Total area: $133$133 | ||
c
What is the width of the second rectangle?
| $10$10 | $\editable{}$ | |
| $7$7 | $70$70 | $63$63 |
| Total area: $133$133 | ||
