We look at the division of 337720 by 12 
We want to divide 337720 by 12.

Moving on to step 1:
12 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 12

Going ahead to step 2:
33 divided by 12 is 2 with a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 24 from 33, we get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 12

Going ahead to step 3:
12 can be fit into 97 8 times, resulting in a remainder of 1.
The next digit of our result is 8. 
Result so far: 28.0
Subtract 96 from 97 to get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 12

Going ahead to step 4:
12 goes into 17 1 times with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 281.0
If we take 12 away from 17, we end up with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 12

On to step 5:
12 can be fit into 52 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 2814.0
Deduct 48 from 52 and we're left with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 12

Let's proceed to step 6:
When dividing 40 by 12, we get 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 28143.0
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
When dividing 40 by 12, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 28143.3
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
The number 12 fits into 40 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 28143.33
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 28143.33 and a remainder of 0.004.
