337900 divided by 12 
We want to figure out the number of times 337900 can be divided by 12.

Going ahead 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
Subtracting 0 from 3 leaves us with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 12

Going ahead to step 2:
If we divide 33 by 12, we get 2 and a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 24 from 33 leaves us with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 12

Going ahead to step 3:
12 goes into 97 8 times with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Deduct 96 from 97 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 12

Let's proceed to step 4:
12 goes into 19 1 times with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 281.0
Subtract 12 from 19 to get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 12

Moving on to step 5:
When dividing 70 by 12, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 2815.0
The remainder is 10 after subtracting 60 from 70.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 12

Going ahead to step 6:
100 divided by 12 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 28158.0
If we subtract 96 from 100, we 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.

Moving on to step 7:
If we divide 40 by 12, we get 3 and a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 28158.3
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.

On to step 8:
40 divided by 12 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 28158.33
Deduct 36 from 40 and we're left 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.

After the division, we end up with 28158.33 and a remainder of 0.004.
