We look at the division of 380023 by 12 
We want to divide 380023 by 12.

On to step 1:
The number 12 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 12

Going ahead to step 2:
When dividing 38 by 12, we get 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 36 away from 38, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 12

Moving on to step 3:
The number 12 fits into 20 1 times, leaving a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtract 12 from 20 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 12

Moving on to step 4:
80 divided by 12 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 316.0
The remainder is 8 after subtracting 72 from 80.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 12

Going ahead to step 5:
The number 12 fits into 82 6 times, leaving a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 3166.0
Subtract 72 from 82 to get 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 12

Step 6:
12 goes into 103 8 times with a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 31668.0
Subtracting 96 from 103 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
If we divide 70 by 12, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 31668.5
Deduct 60 from 70 and we're left 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.

Advancing 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: 31668.58
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.

Step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 31668.583
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.

Step 10:
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: 31668.5833
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.

The final result is 31668.5833 with a remainder of 4e-05.
