We're dividing 115278 by 15 
Our goal is to divide 115278 by 15.

Going ahead to step 1:
15 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 15

On to step 2:
15 can be fit into 11 0 times, resulting in a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 15

Step 3:
The number 15 fits into 115 7 times, leaving a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 105 away from 115, we end up with 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 15

Moving on to step 4:
102 divided by 15 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
Deduct 90 from 102 and we're left with 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 15

Going ahead to step 5:
15 goes into 127 8 times with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 768.0
If we subtract 120 from 127, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 15

Step 6:
15 can be fit into 78 5 times, resulting in a remainder of 3.
The next digit of our result is 5. 
Result so far: 7685.0
The remainder is 3 after subtracting 75 from 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
If we divide 30 by 15, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 7685.2
Deduct 30 from 30 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.

Advancing to step 8:
0 divided by 15 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7685.2
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.

Step 9:
15 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7685.2
Subtract 0 from 0 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.

The final outcome is 7685.2, with a leftover of 0.0.
