We look at the division of 3649318 by 309 
We're looking to find how many times 309 goes into 3649318.

Step 1:
3 divided by 309 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 309

Going ahead to step 2:
The number 309 fits into 36 0 times, leaving a remainder of 36.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Append the next digit (4) from the dividend to 36 and continue with: 364 / 309

Step 3:
When dividing 364 by 309, we get 1 with a remainder of 55.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 309 from 364 leaves us with 55.
Grab the next digit (9) from the dividend, add it to 55, then carry on: 559 / 309

On to step 4:
When dividing 559 by 309, we get 1 with a remainder of 250.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 309 from 559 and we're left with 250.
Bring next digit (3) of the dividend behind the 250 and repeat the process: 2503 / 309

Moving on to step 5:
309 can be fit into 2503 8 times, resulting in a remainder of 31.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
Subtracting 2472 from 2503 leaves us with 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 309

Going ahead to step 6:
309 goes into 311 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1181.0
Subtracting 309 from 311 leaves us with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 309

Let's proceed to step 7:
28 divided by 309 is 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 11810.0
Subtracting 0 from 28 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
280 divided by 309 is 0 with a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 11810.0
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 9:
The number 309 fits into 2800 9 times, leaving a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 11810.09
The remainder is 19 after subtracting 2781 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 10:
309 goes into 190 0 times with a remainder of 190.
Use 0 as the next digit of our solution. 
Result so far: 11810.09
The remainder is 190 after subtracting 0 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 11:
309 can be fit into 1900 6 times, resulting in a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 11810.0906
If we take 1854 away from 1900, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
If we divide 460 by 309, we get 1 and a remainder of 151.
The number 1 becomes the next digit in our result. 
Result so far: 11810.09061
Subtract 309 from 460 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Step 13:
309 goes into 1510 4 times with a remainder of 274.
Write down 4 as next digit of the result. 
Result so far: 11810.090614
If we subtract 1236 from 1510, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 14:
2740 divided by 309 is 8 with a remainder of 268.
Write down 8 as next digit of the result. 
Result so far: 11810.0906148
Subtract 2472 from 2740 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 15:
When dividing 2680 by 309, we get 8 with a remainder of 208.
Write down 8 as next digit of the result. 
Result so far: 11810.09061488
If we subtract 2472 from 2680, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

After the division, we end up with 11810.09061488 and a remainder of 2.08e-07.
