67648586 ÷ 664 
Let's see how many times 664 fits into 67648586.

Let's proceed to step 1:
The number 664 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 664

Moving on to step 2:
664 can be fit into 67 0 times, resulting in a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Bring next digit (6) of the dividend behind the 67 and repeat the process: 676 / 664

Let's proceed to step 3:
If we divide 676 by 664, we get 1 and a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 664 away from 676, we end up with 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 664

Let's proceed to step 4:
664 goes into 124 0 times with a remainder of 124.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 124 after subtracting 0 from 124.
Take the next digit (8) from the dividend and append it to 124, then repeat: 1248 / 664

Step 5:
If we divide 1248 by 664, we get 1 and a remainder of 584.
Use 1 as the next digit of our solution. 
Result so far: 101.0
If we take 664 away from 1248, we end up with 584.
Take the next digit (5) from the dividend and append it to 584, then repeat: 5845 / 664

Let's proceed to step 6:
664 goes into 5845 8 times with a remainder of 533.
The next digit of our result is 8. 
Result so far: 1018.0
Subtract 5312 from 5845 to get 533.
Take the next digit (8) from the dividend and append it to 533, then repeat: 5338 / 664

On to step 7:
If we divide 5338 by 664, we get 8 and a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 10188.0
If we subtract 5312 from 5338, we get 26.
Fetch the next digit (6) from the dividend, attach it to 26 and continue: 266 / 664

Let's proceed to step 8:
266 divided by 664 is 0 with a remainder of 266.
Record the quotient 0 as the next digit in the result. 
Result so far: 101880.0
If we subtract 0 from 266, we get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Let's proceed to step 9:
When dividing 2660 by 664, we get 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 101880.4
If we subtract 2656 from 2660, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
664 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 101880.4
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
400 divided by 664 is 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 101880.4
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 101880.4 with a remainder of 0.04.
