We're dividing 66515 by 88 
Let's see how many times 88 fits into 66515.

On to step 1:
When dividing 6 by 88, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 88

Let's proceed to step 2:
The number 88 fits into 66 0 times, leaving a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Include the next digit (5) from the dividend after 66, then repeat: 665 / 88

On to step 3:
If we divide 665 by 88, we get 7 and a remainder of 49.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 616 from 665 and we're left with 49.
Include the next digit (1) from the dividend after 49, then repeat: 491 / 88

On to step 4:
When dividing 491 by 88, we get 5 with a remainder of 51.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
If we subtract 440 from 491, we get 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 88

Step 5:
The number 88 fits into 515 5 times, leaving a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 755.0
If we take 440 away from 515, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 6:
The number 88 fits into 750 8 times, leaving a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 755.8
If we take 704 away from 750, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 7:
88 can be fit into 460 5 times, resulting in a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 755.85
Deduct 440 from 460 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
The number 88 fits into 200 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 755.852
Subtract 176 from 200 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
88 can be fit into 240 2 times, resulting in a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 755.8522
If we take 176 away from 240, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 755.8522 and a remainder of 0.00064.
