We're dividing 180449 by 12 
Let's see how many times 12 fits into 180449.

Advancing to step 1:
If we divide 1 by 12, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 12

Going ahead to step 2:
12 can be fit into 18 1 times, resulting in a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 6 after subtracting 12 from 18.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 12

Advancing to step 3:
When dividing 60 by 12, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 60 from 60 and we're left with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 12

Moving on to step 4:
When dividing 4 by 12, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
If we subtract 0 from 4, we get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 12

Advancing to step 5:
When dividing 44 by 12, we get 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 1503.0
Subtracting 36 from 44 leaves us with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 12

Going ahead to step 6:
The number 12 fits into 89 7 times, leaving a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 15037.0
Subtracting 84 from 89 leaves us with 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: 15037.4
Deduct 48 from 50 and we're left 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.

Step 8:
12 goes into 20 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 15037.41
Subtracting 12 from 20 leaves us 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.

Step 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 15037.416
Deduct 72 from 80 and we're left 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.

Going ahead to step 10:
12 goes into 80 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 15037.4166
Deduct 72 from 80 and we're left 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.

The final outcome is 15037.4166, with a leftover of 8e-05.
