We're dividing 366511 by 12 
We want to divide 366511 by 12.

On to step 1:
The number 12 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 12

Step 2:
When dividing 36 by 12, we get 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 0 after subtracting 36 from 36.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 12

Advancing to step 3:
If we divide 6 by 12, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Subtract 0 from 6 to get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 12

On to step 4:
12 can be fit into 65 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 305.0
The remainder is 5 after subtracting 60 from 65.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 12

Step 5:
When dividing 51 by 12, we get 4 with a remainder of 3.
The next digit of our result is 4. 
Result so far: 3054.0
If we subtract 48 from 51, we get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 12

Going ahead to step 6:
12 can be fit into 31 2 times, resulting in a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 30542.0
The remainder is 7 after subtracting 24 from 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
The number 12 fits into 70 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 30542.5
If we subtract 60 from 70, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

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: 30542.58
The remainder is 4 after subtracting 96 from 100.
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.
The next digit of our result is 3. 
Result so far: 30542.583
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.

Going ahead to step 10:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 30542.5833
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.

After the division, we end up with 30542.5833 and a remainder of 4e-05.
