We're dividing 12243590 by 664 
We're looking to find how many times 664 goes into 12243590.

Let's proceed to step 1:
If we divide 1 by 664, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 664

Let's proceed to step 2:
The number 664 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 664

Going ahead to step 3:
664 can be fit into 122 0 times, resulting in a remainder of 122.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 122, we get 122.
Fetch the next digit (4) from the dividend, attach it to 122 and continue: 1224 / 664

Step 4:
664 can be fit into 1224 1 times, resulting in a remainder of 560.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 664 from 1224 and we're left with 560.
Include the next digit (3) from the dividend after 560, then repeat: 5603 / 664

Going ahead to step 5:
If we divide 5603 by 664, we get 8 and a remainder of 291.
The next digit of our result is 8. 
Result so far: 18.0
If we take 5312 away from 5603, we end up with 291.
Include the next digit (5) from the dividend after 291, then repeat: 2915 / 664

Step 6:
664 can be fit into 2915 4 times, resulting in a remainder of 259.
Put 4 as the next digit of the answer. 
Result so far: 184.0
If we take 2656 away from 2915, we end up with 259.
Bring next digit (9) of the dividend behind the 259 and repeat the process: 2599 / 664

Going ahead to step 7:
When dividing 2599 by 664, we get 3 with a remainder of 607.
Put 3 as the next digit of the answer. 
Result so far: 1843.0
The remainder is 607 after subtracting 1992 from 2599.
Bring next digit (0) of the dividend behind the 607 and repeat the process: 6070 / 664

Advancing to step 8:
6070 divided by 664 is 9 with a remainder of 94.
Record the quotient 9 as the next digit in the result. 
Result so far: 18439.0
If we take 5976 away from 6070, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 9:
664 goes into 940 1 times with a remainder of 276.
Put 1 as the next digit of the answer. 
Result so far: 18439.1
If we subtract 664 from 940, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Let's proceed to step 10:
664 goes into 2760 4 times with a remainder of 104.
Write down 4 as next digit of the result. 
Result so far: 18439.14
If we subtract 2656 from 2760, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 11:
1040 divided by 664 is 1 with a remainder of 376.
Put 1 as the next digit of the answer. 
Result so far: 18439.141
If we subtract 664 from 1040, we get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 12:
If we divide 3760 by 664, we get 5 and a remainder of 440.
Put 5 as the next digit of the answer. 
Result so far: 18439.1415
The remainder is 440 after subtracting 3320 from 3760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 13:
The number 664 fits into 4400 6 times, leaving a remainder of 416.
Put 6 as the next digit of the answer. 
Result so far: 18439.14156
The remainder is 416 after subtracting 3984 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 14:
664 goes into 4160 6 times with a remainder of 176.
The next digit of our result is 6. 
Result so far: 18439.141566
If we subtract 3984 from 4160, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

After the division, we end up with 18439.141566 and a remainder of 1.76e-05.
