We're dividing 664515 by 88 
We want to divide 664515 by 88.

Step 1:
6 divided by 88 is 0 with 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.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 88

Let's proceed to step 2:
88 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 88

Step 3:
If we divide 664 by 88, we get 7 and a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 616 from 664 and we're left with 48.
Append the next digit (5) from the dividend to 48 and continue with: 485 / 88

Going ahead to step 4:
88 goes into 485 5 times with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 75.0
Deduct 440 from 485 and we're left with 45.
Append the next digit (1) from the dividend to 45 and continue with: 451 / 88

Step 5:
The number 88 fits into 451 5 times, leaving a remainder of 11.
The next digit of our result is 5. 
Result so far: 755.0
Deduct 440 from 451 and we're left with 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 88

Advancing to step 6:
115 divided by 88 is 1 with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 7551.0
Subtracting 88 from 115 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
88 goes into 270 3 times with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 7551.3
Subtracting 264 from 270 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
88 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 7551.3
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
When dividing 600 by 88, we get 6 with a remainder of 72.
The next digit of our result is 6. 
Result so far: 7551.306
The remainder is 72 after subtracting 528 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 10:
88 goes into 720 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 7551.3068
The remainder is 16 after subtracting 704 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
When dividing 160 by 88, we get 1 with a remainder of 72.
The number 1 becomes the next digit in our result. 
Result so far: 7551.30681
The remainder is 72 after subtracting 88 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 12:
88 goes into 720 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 7551.306818
Subtract 704 from 720 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
When dividing 160 by 88, we get 1 with a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 7551.3068181
If we subtract 88 from 160, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 14:
If we divide 720 by 88, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 7551.30681818
If we take 704 away from 720, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 7551.30681818, and the remainder is 1.6e-08.
