Let's go!

168/3=

Set it up:

168/3

Do the
DMS loop:  Division, multiplication, subtraction!

 

Division:

How many times does 3 go into 1?  Hey, 3 doesn't go into 1...  3 is bigger than 1!

No problem...  We'll just use the next number too!

 168/3 step 1
How many times 3 will go into 16?  Three goes into 16 five times with a little extra.  Put that 5 right above the 6: 168/3 step 2

 

Multiplication:

Multiply the 5 and the 3 and put the answer right under the 16:

 168/3 step 3

 

Subtraction:

Do the subtraction...
That's 16 - 15 = 1

 168/3 step 4

First DMS loop done!  Almost there!!

Set it up: 
Drag the 8 down.

That makes it a 18...

 168/3 step 5

Now, let's go back into our DMS loop using the 18!

Division:

How many times 3 will go into 18?  Three goes into 18 cleanly... six times.  Put that 6 right above the 8:

 168/3 step 6

 

Multiplication:

Multiply the 6 and the 3 and put the answer right under the 18:

 168/3 step 7

 

Subtraction:

That's 18 - 18 = 0

Yeah, baby!  Done!

The answer is 56.

 168/3 step 8

Check it!!  56 x 3 should = 168!
