Let's divide 12358493 by 665
Our goal is to divide 12358493 by 665.

Let's proceed to step 1:
The number 665 fits into 1 0 times, leaving 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.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 665

Step 2:
665 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 665

Going ahead to step 3:
The number 665 fits into 123 0 times, leaving a remainder of 123.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 123, we get 123.
Include the next digit (5) from the dividend after 123, then repeat: 1235 / 665

Advancing to step 4:
The number 665 fits into 1235 1 times, leaving a remainder of 570.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 570 after subtracting 665 from 1235.
Bring next digit (8) of the dividend behind the 570 and repeat the process: 5708 / 665

Going ahead to step 5:
When dividing 5708 by 665, we get 8 with a remainder of 388.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we take 5320 away from 5708, we end up with 388.
Fetch the next digit (4) from the dividend, attach it to 388 and continue: 3884 / 665

Advancing to step 6:
If we divide 3884 by 665, we get 5 and a remainder of 559.
Put 5 as the next digit of the answer. 
Result so far: 185.0
The remainder is 559 after subtracting 3325 from 3884.
Append the next digit (9) from the dividend to 559 and continue with: 5599 / 665

Advancing to step 7:
When dividing 5599 by 665, we get 8 with a remainder of 279.
Put 8 as the next digit of the answer. 
Result so far: 1858.0
The remainder is 279 after subtracting 5320 from 5599.
Grab the next digit (3) from the dividend, add it to 279, then carry on: 2793 / 665

Let's proceed to step 8:
665 can be fit into 2793 4 times, resulting in a remainder of 133.
Put 4 as the next digit of the answer. 
Result so far: 18584.0
Subtract 2660 from 2793 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Going ahead to step 9:
The number 665 fits into 1330 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 18584.2
If we subtract 1330 from 1330, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
0 divided by 665 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 18584.2
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
If we divide 0 by 665, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 18584.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 18584.2 and a remainder of 0.0.
