We're dividing 6618664 by 664 
We're looking to find how many times 664 goes into 6618664.

Step 1:
664 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 664

Step 2:
If we divide 66 by 664, we get 0 and a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 664

Moving on to step 3:
664 can be fit into 661 0 times, resulting in a remainder of 661.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 661 and we're left with 661.
Include the next digit (8) from the dividend after 661, then repeat: 6618 / 664

Let's proceed to step 4:
664 can be fit into 6618 9 times, resulting in a remainder of 642.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 5976 from 6618 and we're left with 642.
Append the next digit (6) from the dividend to 642 and continue with: 6426 / 664

Going ahead to step 5:
664 can be fit into 6426 9 times, resulting in a remainder of 450.
Write down 9 as next digit of the result. 
Result so far: 99.0
If we subtract 5976 from 6426, we get 450.
Take the next digit (6) from the dividend and append it to 450, then repeat: 4506 / 664

Step 6:
If we divide 4506 by 664, we get 6 and a remainder of 522.
Put 6 as the next digit of the answer. 
Result so far: 996.0
The remainder is 522 after subtracting 3984 from 4506.
Fetch the next digit (4) from the dividend, attach it to 522 and continue: 5224 / 664

Advancing to step 7:
The number 664 fits into 5224 7 times, leaving a remainder of 576.
Put 7 as the next digit of the answer. 
Result so far: 9967.0
Deduct 4648 from 5224 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.

Step 8:
When dividing 5760 by 664, we get 8 with a remainder of 448.
Write down 8 as next digit of the result. 
Result so far: 9967.8
Subtracting 5312 from 5760 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 9:
The number 664 fits into 4480 6 times, leaving a remainder of 496.
The number 6 becomes the next digit in our result. 
Result so far: 9967.86
Deduct 3984 from 4480 and we're left with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Moving on to step 10:
664 goes into 4960 7 times with a remainder of 312.
The number 7 becomes the next digit in our result. 
Result so far: 9967.867
Subtract 4648 from 4960 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Advancing to step 11:
If we divide 3120 by 664, we get 4 and a remainder of 464.
The number 4 becomes the next digit in our result. 
Result so far: 9967.8674
If we subtract 2656 from 3120, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

On to step 12:
664 goes into 4640 6 times with a remainder of 656.
The next digit of our result is 6. 
Result so far: 9967.86746
If we subtract 3984 from 4640, we get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

On to step 13:
If we divide 6560 by 664, we get 9 and a remainder of 584.
The next digit of our result is 9. 
Result so far: 9967.867469
If we take 5976 away from 6560, we end up with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Step 14:
5840 divided by 664 is 8 with a remainder of 528.
Put 8 as the next digit of the answer. 
Result so far: 9967.8674698
If we subtract 5312 from 5840, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Going ahead to step 15:
664 can be fit into 5280 7 times, resulting in a remainder of 632.
Record the quotient 7 as the next digit in the result. 
Result so far: 9967.86746987
Subtract 4648 from 5280 to get 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Our division results in 9967.86746987 with a remaining 6.32e-07.
