We're dividing 81515489 by 110 
Our goal is to divide 81515489 by 110.

Let's proceed to step 1:
110 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 110

Going ahead to step 2:
When dividing 81 by 110, we get 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Include the next digit (5) from the dividend after 81, then repeat: 815 / 110

Step 3:
110 can be fit into 815 7 times, resulting in a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 770 away from 815, we end up with 45.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 110

Let's proceed to step 4:
110 goes into 451 4 times with a remainder of 11.
The next digit of our result is 4. 
Result so far: 74.0
If we subtract 440 from 451, we get 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 110

Step 5:
110 can be fit into 115 1 times, resulting in a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 741.0
The remainder is 5 after subtracting 110 from 115.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 110

On to step 6:
If we divide 54 by 110, we get 0 and a remainder of 54.
The next digit of our result is 0. 
Result so far: 7410.0
Subtracting 0 from 54 leaves us with 54.
Include the next digit (8) from the dividend after 54, then repeat: 548 / 110

Advancing to step 7:
110 goes into 548 4 times with a remainder of 108.
Write down 4 as next digit of the result. 
Result so far: 74104.0
If we take 440 away from 548, we end up with 108.
Take the next digit (9) from the dividend and append it to 108, then repeat: 1089 / 110

Let's proceed to step 8:
The number 110 fits into 1089 9 times, leaving a remainder of 99.
Put 9 as the next digit of the answer. 
Result so far: 741049.0
Subtract 990 from 1089 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 9:
The number 110 fits into 990 9 times, leaving a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 741049.9
Subtract 990 from 990 to 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 10:
110 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 741049.9
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.

On to step 11:
When dividing 0 by 110, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 741049.9
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 741049.9 and a remainder of 0.0.
