We're dividing 481663 by 12 
We're looking to find how many times 12 goes into 481663.

On to step 1:
The number 12 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 12

Going ahead to step 2:
The number 12 fits into 48 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 48 from 48, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 12

Advancing to step 3:
1 divided by 12 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Subtract 0 from 1 to get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 12

Going ahead to step 4:
When dividing 16 by 12, we get 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 401.0
Subtract 12 from 16 to get 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 12

Advancing to step 5:
The number 12 fits into 46 3 times, leaving a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 4013.0
The remainder is 10 after subtracting 36 from 46.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 12

Advancing to step 6:
12 can be fit into 103 8 times, resulting in a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 40138.0
If we take 96 away from 103, we end up 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:
12 goes into 70 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 40138.5
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.

Let's proceed to step 8:
If we divide 100 by 12, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 40138.58
Deduct 96 from 100 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.

Moving on to step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 40138.583
The remainder is 4 after subtracting 36 from 40.
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.
Record the quotient 3 as the next digit in the result. 
Result so far: 40138.5833
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.

The quotient of the division is 40138.5833, and the remainder is 4e-05.
