337897 divided by 12 
We want to divide 337897 by 12.

Let's proceed to step 1:
If we divide 3 by 12, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 12

Going ahead to step 2:
If we divide 33 by 12, we get 2 and a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 24 from 33 and we're left with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 12

On to step 3:
97 divided by 12 is 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we subtract 96 from 97, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 12

Step 4:
12 goes into 18 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 281.0
The remainder is 6 after subtracting 12 from 18.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 12

On to step 5:
69 divided by 12 is 5 with a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 2815.0
If we subtract 60 from 69, we get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 12

Advancing to step 6:
97 divided by 12 is 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 28158.0
If we take 96 away from 97, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
The number 12 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 28158.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
100 divided by 12 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 28158.08
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 9:
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: 28158.083
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.

Moving on to step 10:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 28158.0833
Subtracting 36 from 40 leaves us 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.

Our division results in 28158.0833 with a remaining 4e-05.
