We're dividing 12720266 by 363 
Let's see how many times 363 fits into 12720266.

Moving on to step 1:
If we divide 1 by 363, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 363

Advancing to step 2:
12 divided by 363 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 363

Step 3:
The number 363 fits into 127 0 times, leaving a remainder of 127.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 127, we get 127.
Fetch the next digit (2) from the dividend, attach it to 127 and continue: 1272 / 363

Step 4:
363 can be fit into 1272 3 times, resulting in a remainder of 183.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 1089 from 1272, we get 183.
Append the next digit (0) from the dividend to 183 and continue with: 1830 / 363

Step 5:
363 goes into 1830 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 35.0
Subtract 1815 from 1830 to get 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 363

Step 6:
If we divide 152 by 363, we get 0 and a remainder of 152.
The number 0 becomes the next digit in our result. 
Result so far: 350.0
Subtracting 0 from 152 leaves us with 152.
Take the next digit (6) from the dividend and append it to 152, then repeat: 1526 / 363

Moving on to step 7:
The number 363 fits into 1526 4 times, leaving a remainder of 74.
Record the quotient 4 as the next digit in the result. 
Result so far: 3504.0
Subtract 1452 from 1526 to get 74.
Bring next digit (6) of the dividend behind the 74 and repeat the process: 746 / 363

Step 8:
363 can be fit into 746 2 times, resulting in a remainder of 20.
The next digit of our result is 2. 
Result so far: 35042.0
If we subtract 726 from 746, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
When dividing 200 by 363, we get 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 35042.0
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 10:
363 goes into 2000 5 times with a remainder of 185.
The next digit of our result is 5. 
Result so far: 35042.05
If we subtract 1815 from 2000, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 11:
If we divide 1850 by 363, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 35042.055
Subtracting 1815 from 1850 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 35042.055, and the remainder is 0.0035.
