66263907 divided by 664 
We want to divide 66263907 by 664.

Step 1:
664 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 664

Going ahead to step 2:
66 divided by 664 is 0 with 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.
Fetch the next digit (2) from the dividend, attach it to 66 and continue: 662 / 664

On to step 3:
664 goes into 662 0 times with a remainder of 662.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 662, we get 662.
Fetch the next digit (6) from the dividend, attach it to 662 and continue: 6626 / 664

Going ahead to step 4:
664 goes into 6626 9 times with a remainder of 650.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 5976 away from 6626, we end up with 650.
Include the next digit (3) from the dividend after 650, then repeat: 6503 / 664

Advancing to step 5:
If we divide 6503 by 664, we get 9 and a remainder of 527.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
Subtract 5976 from 6503 to get 527.
Fetch the next digit (9) from the dividend, attach it to 527 and continue: 5279 / 664

On to step 6:
If we divide 5279 by 664, we get 7 and a remainder of 631.
The number 7 becomes the next digit in our result. 
Result so far: 997.0
Subtracting 4648 from 5279 leaves us with 631.
Append the next digit (0) from the dividend to 631 and continue with: 6310 / 664

Advancing to step 7:
6310 divided by 664 is 9 with a remainder of 334.
Write down 9 as next digit of the result. 
Result so far: 9979.0
If we take 5976 away from 6310, we end up with 334.
Append the next digit (7) from the dividend to 334 and continue with: 3347 / 664

Advancing to step 8:
664 goes into 3347 5 times with a remainder of 27.
Write down 5 as next digit of the result. 
Result so far: 99795.0
If we subtract 3320 from 3347, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 9:
270 divided by 664 is 0 with a remainder of 270.
Put 0 as the next digit of the answer. 
Result so far: 99795.0
Subtracting 0 from 270 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 10:
664 goes into 2700 4 times with a remainder of 44.
The next digit of our result is 4. 
Result so far: 99795.04
Subtract 2656 from 2700 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 11:
When dividing 440 by 664, we get 0 with a remainder of 440.
Write down 0 as next digit of the result. 
Result so far: 99795.04
Subtracting 0 from 440 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 12:
664 goes into 4400 6 times with a remainder of 416.
The next digit of our result is 6. 
Result so far: 99795.0406
If we take 3984 away from 4400, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 13:
664 goes into 4160 6 times with a remainder of 176.
Write down 6 as next digit of the result. 
Result so far: 99795.04066
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 99795.04066 and a remainder of 0.000176.
