We're dividing 12721484 by 115 
Let's see how many times 115 fits into 12721484.

Step 1:
If we divide 1 by 115, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 115

Going ahead to step 2:
When dividing 12 by 115, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 115

Going ahead to step 3:
127 divided by 115 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 115 from 127 to get 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 115

Going ahead to step 4:
When dividing 122 by 115, we get 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 115 from 122 and we're left with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 115

Advancing to step 5:
If we divide 71 by 115, we get 0 and a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
Deduct 0 from 71 and we're left with 71.
Bring next digit (4) of the dividend behind the 71 and repeat the process: 714 / 115

On to step 6:
The number 115 fits into 714 6 times, leaving a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 1106.0
If we take 690 away from 714, we end up with 24.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 115

Moving on to step 7:
If we divide 248 by 115, we get 2 and a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 11062.0
If we take 230 away from 248, we end up with 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 115

Let's proceed to step 8:
115 can be fit into 184 1 times, resulting in a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 110621.0
Subtract 115 from 184 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 9:
115 can be fit into 690 6 times, resulting in a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 110621.6
Deduct 690 from 690 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.

Going ahead to step 10:
115 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 110621.6
If we take 0 away from 0, we end up 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.

Advancing to step 11:
If we divide 0 by 115, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 110621.6
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 110621.6, with a leftover of 0.0.
