Let's divide 81516887 by 88
Our goal is to divide 81516887 by 88.

On to step 1:
If we divide 8 by 88, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 88

Moving on to step 2:
The number 88 fits into 81 0 times, leaving a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Fetch the next digit (5) from the dividend, attach it to 81 and continue: 815 / 88

On to step 3:
If we divide 815 by 88, we get 9 and a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 792 from 815 to get 23.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 88

Moving on to step 4:
When dividing 231 by 88, we get 2 with a remainder of 55.
The next digit of our result is 2. 
Result so far: 92.0
Subtracting 176 from 231 leaves us with 55.
Grab the next digit (6) from the dividend, add it to 55, then carry on: 556 / 88

On to step 5:
If we divide 556 by 88, we get 6 and a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 926.0
Deduct 528 from 556 and we're left with 28.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 88

On to step 6:
When dividing 288 by 88, we get 3 with a remainder of 24.
The next digit of our result is 3. 
Result so far: 9263.0
Subtract 264 from 288 to get 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 88

Going ahead to step 7:
248 divided by 88 is 2 with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 92632.0
Subtracting 176 from 248 leaves us with 72.
Take the next digit (7) from the dividend and append it to 72, then repeat: 727 / 88

Advancing to step 8:
The number 88 fits into 727 8 times, leaving a remainder of 23.
The number 8 becomes the next digit in our result. 
Result so far: 926328.0
Subtracting 704 from 727 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 9:
The number 88 fits into 230 2 times, leaving a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 926328.2
If we take 176 away from 230, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 10:
88 can be fit into 540 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 926328.26
If we subtract 528 from 540, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
88 goes into 120 1 times with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 926328.261
The remainder is 32 after subtracting 88 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
If we divide 320 by 88, we get 3 and a remainder of 56.
Write down 3 as next digit of the result. 
Result so far: 926328.2613
The remainder is 56 after subtracting 264 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 13:
88 can be fit into 560 6 times, resulting in a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 926328.26136
Subtracting 528 from 560 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
The number 88 fits into 320 3 times, leaving a remainder of 56.
The number 3 becomes the next digit in our result. 
Result so far: 926328.261363
Subtract 264 from 320 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 15:
When dividing 560 by 88, we get 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 926328.2613636
If we subtract 528 from 560, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 16:
320 divided by 88 is 3 with a remainder of 56.
The number 3 becomes the next digit in our result. 
Result so far: 926328.26136363
Subtracting 264 from 320 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The quotient of the division is 926328.26136363, and the remainder is 5.6e-08.
