12397385 divided by 664 
We're looking to find how many times 664 goes into 12397385.

Going ahead to step 1:
664 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 664

On to step 2:
664 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 664

Step 3:
The number 664 fits into 123 0 times, leaving 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 (9) from the dividend, attach it to 123 and continue: 1239 / 664

On to step 4:
The number 664 fits into 1239 1 times, leaving a remainder of 575.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 664 from 1239, we get 575.
Include the next digit (7) from the dividend after 575, then repeat: 5757 / 664

On to step 5:
664 can be fit into 5757 8 times, resulting in a remainder of 445.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 5312 from 5757 and we're left with 445.
Include the next digit (3) from the dividend after 445, then repeat: 4453 / 664

Step 6:
664 goes into 4453 6 times with a remainder of 469.
The number 6 becomes the next digit in our result. 
Result so far: 186.0
Deduct 3984 from 4453 and we're left with 469.
Append the next digit (8) from the dividend to 469 and continue with: 4698 / 664

Let's proceed to step 7:
664 can be fit into 4698 7 times, resulting in a remainder of 50.
Use 7 as the next digit of our solution. 
Result so far: 1867.0
If we subtract 4648 from 4698, we get 50.
Bring next digit (5) of the dividend behind the 50 and repeat the process: 505 / 664

Step 8:
If we divide 505 by 664, we get 0 and a remainder of 505.
The next digit of our result is 0. 
Result so far: 18670.0
If we take 0 away from 505, we end up with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Going ahead to step 9:
664 can be fit into 5050 7 times, resulting in a remainder of 402.
The next digit of our result is 7. 
Result so far: 18670.7
Subtract 4648 from 5050 to get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Step 10:
If we divide 4020 by 664, we get 6 and a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 18670.76
The remainder is 36 after subtracting 3984 from 4020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
360 divided by 664 is 0 with a remainder of 360.
The number 0 becomes the next digit in our result. 
Result so far: 18670.76
Deduct 0 from 360 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 12:
664 can be fit into 3600 5 times, resulting in a remainder of 280.
Record the quotient 5 as the next digit in the result. 
Result so far: 18670.7605
Subtract 3320 from 3600 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 13:
664 goes into 2800 4 times with a remainder of 144.
The number 4 becomes the next digit in our result. 
Result so far: 18670.76054
Subtract 2656 from 2800 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 14:
1440 divided by 664 is 2 with a remainder of 112.
Record the quotient 2 as the next digit in the result. 
Result so far: 18670.760542
Subtracting 1328 from 1440 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 15:
1120 divided by 664 is 1 with a remainder of 456.
The number 1 becomes the next digit in our result. 
Result so far: 18670.7605421
Subtract 664 from 1120 to get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

On to step 16:
When dividing 4560 by 664, we get 6 with a remainder of 576.
Use 6 as the next digit of our solution. 
Result so far: 18670.76054216
Deduct 3984 from 4560 and we're left with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

In conclusion, the division gives 18670.76054216 with a balance of 5.76e-07.
