We're dividing 494394 by 12 
Let's see how many times 12 fits into 494394.

Let's proceed to step 1:
12 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our 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

Going ahead to step 2:
49 divided by 12 is 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 48 from 49 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 12

Going ahead to step 3:
12 goes into 14 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 41.0
Subtract 12 from 14 to get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 12

Step 4:
23 divided by 12 is 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 411.0
Deduct 12 from 23 and we're left with 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 12

Moving on to step 5:
12 goes into 119 9 times with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 4119.0
If we subtract 108 from 119, we get 11.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 12

Going ahead to step 6:
The number 12 fits into 114 9 times, leaving a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 41199.0
If we take 108 away from 114, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 41199.5
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
When dividing 0 by 12, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 41199.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
0 divided by 12 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 41199.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 41199.5, and the remainder is 0.0.
