We're dividing 12366203 by 683 
Our goal is to divide 12366203 by 683.

On to step 1:
When dividing 1 by 683, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 683

Advancing to step 2:
683 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 683

Step 3:
683 can be fit into 123 0 times, resulting in a remainder of 123.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 123 after subtracting 0 from 123.
Fetch the next digit (6) from the dividend, attach it to 123 and continue: 1236 / 683

Moving on to step 4:
The number 683 fits into 1236 1 times, leaving a remainder of 553.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 683 from 1236 and we're left with 553.
Bring next digit (6) of the dividend behind the 553 and repeat the process: 5536 / 683

Moving on to step 5:
The number 683 fits into 5536 8 times, leaving a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 72 after subtracting 5464 from 5536.
Include the next digit (2) from the dividend after 72, then repeat: 722 / 683

Let's proceed to step 6:
When dividing 722 by 683, we get 1 with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 181.0
If we subtract 683 from 722, we get 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 683

Advancing to step 7:
When dividing 390 by 683, we get 0 with a remainder of 390.
Put 0 as the next digit of the answer. 
Result so far: 1810.0
Deduct 0 from 390 and we're left with 390.
Append the next digit (3) from the dividend to 390 and continue with: 3903 / 683

Advancing to step 8:
If we divide 3903 by 683, we get 5 and a remainder of 488.
Put 5 as the next digit of the answer. 
Result so far: 18105.0
Deduct 3415 from 3903 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Going ahead to step 9:
4880 divided by 683 is 7 with a remainder of 99.
Write down 7 as next digit of the result. 
Result so far: 18105.7
Subtracting 4781 from 4880 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Let's proceed to step 10:
The number 683 fits into 990 1 times, leaving a remainder of 307.
Put 1 as the next digit of the answer. 
Result so far: 18105.71
Subtract 683 from 990 to get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Step 11:
When dividing 3070 by 683, we get 4 with a remainder of 338.
Write down 4 as next digit of the result. 
Result so far: 18105.714
Deduct 2732 from 3070 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Going ahead to step 12:
When dividing 3380 by 683, we get 4 with a remainder of 648.
Use 4 as the next digit of our solution. 
Result so far: 18105.7144
If we subtract 2732 from 3380, we get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

The final outcome is 18105.7144, with a leftover of 0.00648.
