338271 ÷ 12 
We want to figure out the number of times 338271 can be divided by 12.

Advancing to step 1:
12 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 12

Going ahead to step 2:
12 can be fit into 33 2 times, resulting in a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 24 from 33 to get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 12

Step 3:
When dividing 98 by 12, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Deduct 96 from 98 and we're left with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 12

On to step 4:
22 divided by 12 is 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 281.0
Deduct 12 from 22 and we're left with 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 12

On to step 5:
When dividing 107 by 12, we get 8 with a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 2818.0
If we take 96 away from 107, we end up with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 12

Moving on to step 6:
111 divided by 12 is 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 28189.0
If we subtract 108 from 111, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
When dividing 30 by 12, we get 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 28189.2
The remainder is 6 after subtracting 24 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
When dividing 60 by 12, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 28189.25
Subtract 60 from 60 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 28189.25
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 28189.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 28189.25 with a remaining 0.0.
