Let's divide 499780 by 12
Our goal is to divide 499780 by 12.

Step 1:
12 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 12

Step 2:
12 goes into 49 4 times with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 48 from 49, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 12

Going ahead to step 3:
12 goes into 19 1 times with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 41.0
Deduct 12 from 19 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 12

Moving on to step 4:
77 divided by 12 is 6 with a remainder of 5.
The next digit of our result is 6. 
Result so far: 416.0
Deduct 72 from 77 and we're left with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 12

On to step 5:
If we divide 58 by 12, we get 4 and a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 4164.0
Deduct 48 from 58 and we're left with 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 12

Going ahead to step 6:
100 divided by 12 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 41648.0
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.

On to step 7:
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: 41648.3
If we take 36 away from 40, we end up 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 8:
12 goes into 40 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 41648.33
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.

After the division, we end up with 41648.33 and a remainder of 0.004.
