Let's divide 115499 by 15
We're looking to find how many times 15 goes into 115499.

On to step 1:
1 divided by 15 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 15

On to step 2:
15 goes into 11 0 times with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 11, we end up with 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 15

Let's proceed to step 3:
The number 15 fits into 115 7 times, leaving a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 105 from 115 to get 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 15

Advancing to step 4:
If we divide 104 by 15, we get 6 and a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 76.0
The remainder is 14 after subtracting 90 from 104.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 15

On to step 5:
15 goes into 149 9 times with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 769.0
Deduct 135 from 149 and we're left with 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 15

Moving on to step 6:
The number 15 fits into 149 9 times, leaving a remainder of 14.
The next digit of our result is 9. 
Result so far: 7699.0
If we subtract 135 from 149, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
140 divided by 15 is 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 7699.9
Subtract 135 from 140 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 7699.93
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
15 goes into 50 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 7699.933
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 7699.933 and a remainder of 0.0005.
