664664 ÷ 88 
We're looking to find how many times 88 goes into 664664.

Moving on to step 1:
The number 88 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
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 88

Advancing to step 2:
When dividing 66 by 88, we get 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Grab the next digit (4) from the dividend, add it to 66, then carry on: 664 / 88

Going ahead to step 3:
88 goes into 664 7 times with a remainder of 48.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 48 after subtracting 616 from 664.
Include the next digit (6) from the dividend after 48, then repeat: 486 / 88

Step 4:
When dividing 486 by 88, we get 5 with a remainder of 46.
The next digit of our result is 5. 
Result so far: 75.0
Subtract 440 from 486 to get 46.
Append the next digit (6) from the dividend to 46 and continue with: 466 / 88

On to step 5:
88 goes into 466 5 times with a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 755.0
The remainder is 26 after subtracting 440 from 466.
Grab the next digit (4) from the dividend, add it to 26, then carry on: 264 / 88

Step 6:
88 goes into 264 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 7553.0
If we subtract 264 from 264, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
88 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 7553.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
88 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7553.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 7553.0, with a leftover of 0.0.
