768339 divided by 15 
We want to figure out the number of times 768339 can be divided by 15.

Let's proceed to step 1:
The number 15 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 15

On to step 2:
If we divide 76 by 15, we get 5 and a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 1 after subtracting 75 from 76.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 15

Moving on to step 3:
If we divide 18 by 15, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 51.0
The remainder is 3 after subtracting 15 from 18.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 15

Step 4:
If we divide 33 by 15, we get 2 and a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 512.0
Subtracting 30 from 33 leaves us with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 15

Moving on to step 5:
15 goes into 33 2 times with a remainder of 3.
The next digit of our result is 2. 
Result so far: 5122.0
If we take 30 away from 33, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 15

Advancing to step 6:
15 goes into 39 2 times with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 51222.0
If we take 30 away from 39, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
15 can be fit into 90 6 times, resulting in a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 51222.6
If we subtract 90 from 90, 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.

On to step 8:
0 divided by 15 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 51222.6
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.

Let's proceed to step 9:
15 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 51222.6
Subtracting 0 from 0 leaves us 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.

Our division results in 51222.6 with a remaining 0.0.
