We divide 390581 by 12
We're looking to find how many times 12 goes into 390581.

Moving on to step 1:
3 divided by 12 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 12

Step 2:
12 can be fit into 39 3 times, resulting in a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 36 from 39 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 12

On to step 3:
If we divide 30 by 12, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 32.0
If we take 24 away from 30, we end up with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 12

Let's proceed to step 4:
12 goes into 65 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 325.0
Deduct 60 from 65 and we're left with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 12

Step 5:
12 goes into 58 4 times with a remainder of 10.
The next digit of our result is 4. 
Result so far: 3254.0
If we take 48 away from 58, we end up with 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 12

On to step 6:
The number 12 fits into 101 8 times, leaving a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 32548.0
Subtract 96 from 101 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
12 can be fit into 50 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 32548.4
Subtracting 48 from 50 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
If we divide 20 by 12, we get 1 and a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 32548.41
If we take 12 away from 20, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
12 goes into 80 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 32548.416
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
If we divide 80 by 12, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 32548.4166
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 32548.4166, and the remainder is 8e-05.
