We're dividing 668120 by 72 
We want to figure out the number of times 668120 can be divided by 72.

On to step 1:
6 divided by 72 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 72

Advancing to step 2:
When dividing 66 by 72, we get 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Bring next digit (8) of the dividend behind the 66 and repeat the process: 668 / 72

Step 3:
When dividing 668 by 72, we get 9 with a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 648 from 668 and we're left with 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 72

Advancing to step 4:
72 can be fit into 201 2 times, resulting in a remainder of 57.
Use 2 as the next digit of our solution. 
Result so far: 92.0
Subtracting 144 from 201 leaves us with 57.
Include the next digit (2) from the dividend after 57, then repeat: 572 / 72

Advancing to step 5:
When dividing 572 by 72, we get 7 with a remainder of 68.
Write down 7 as next digit of the result. 
Result so far: 927.0
Subtract 504 from 572 to get 68.
Fetch the next digit (0) from the dividend, attach it to 68 and continue: 680 / 72

Advancing to step 6:
The number 72 fits into 680 9 times, leaving a remainder of 32.
Use 9 as the next digit of our solution. 
Result so far: 9279.0
Deduct 648 from 680 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 7:
If we divide 320 by 72, we get 4 and a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 9279.4
If we take 288 away from 320, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 8:
320 divided by 72 is 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 9279.44
Deduct 288 from 320 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 9279.44 with a remaining 0.032.
