We're dividing 12279645 by 303 
Our goal is to divide 12279645 by 303.

Advancing to step 1:
303 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 303

On to step 2:
The number 303 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 303

Advancing to step 3:
The number 303 fits into 122 0 times, leaving a remainder of 122.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 122, we end up with 122.
Bring next digit (7) of the dividend behind the 122 and repeat the process: 1227 / 303

Advancing to step 4:
303 goes into 1227 4 times with a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 1212 from 1227 to get 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 303

Moving on to step 5:
The number 303 fits into 159 0 times, leaving a remainder of 159.
The next digit of our result is 0. 
Result so far: 40.0
Deduct 0 from 159 and we're left with 159.
Grab the next digit (6) from the dividend, add it to 159, then carry on: 1596 / 303

On to step 6:
303 goes into 1596 5 times with a remainder of 81.
The next digit of our result is 5. 
Result so far: 405.0
If we subtract 1515 from 1596, we get 81.
Fetch the next digit (4) from the dividend, attach it to 81 and continue: 814 / 303

Advancing to step 7:
The number 303 fits into 814 2 times, leaving a remainder of 208.
Record the quotient 2 as the next digit in the result. 
Result so far: 4052.0
The remainder is 208 after subtracting 606 from 814.
Fetch the next digit (5) from the dividend, attach it to 208 and continue: 2085 / 303

Advancing to step 8:
303 can be fit into 2085 6 times, resulting in a remainder of 267.
The next digit of our result is 6. 
Result so far: 40526.0
If we take 1818 away from 2085, we end up with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

On to step 9:
When dividing 2670 by 303, we get 8 with a remainder of 246.
Write down 8 as next digit of the result. 
Result so far: 40526.8
The remainder is 246 after subtracting 2424 from 2670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Going ahead to step 10:
When dividing 2460 by 303, we get 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 40526.88
Deduct 2424 from 2460 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 40526.88 with a remaining 0.036.
