15303399 ÷ 768 
Our goal is to divide 15303399 by 768.

Going ahead to step 1:
1 divided by 768 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 768

Step 2:
If we divide 15 by 768, we get 0 and a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 768

Let's proceed to step 3:
768 can be fit into 153 0 times, resulting in a remainder of 153.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 153, we get 153.
Grab the next digit (0) from the dividend, add it to 153, then carry on: 1530 / 768

Let's proceed to step 4:
768 can be fit into 1530 1 times, resulting in a remainder of 762.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 768 from 1530 leaves us with 762.
Fetch the next digit (3) from the dividend, attach it to 762 and continue: 7623 / 768

Step 5:
The number 768 fits into 7623 9 times, leaving a remainder of 711.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 6912 away from 7623, we end up with 711.
Append the next digit (3) from the dividend to 711 and continue with: 7113 / 768

Moving on to step 6:
768 goes into 7113 9 times with a remainder of 201.
Record the quotient 9 as the next digit in the result. 
Result so far: 199.0
If we subtract 6912 from 7113, we get 201.
Fetch the next digit (9) from the dividend, attach it to 201 and continue: 2019 / 768

Advancing to step 7:
When dividing 2019 by 768, we get 2 with a remainder of 483.
The next digit of our result is 2. 
Result so far: 1992.0
Deduct 1536 from 2019 and we're left with 483.
Append the next digit (9) from the dividend to 483 and continue with: 4839 / 768

Advancing to step 8:
The number 768 fits into 4839 6 times, leaving a remainder of 231.
The next digit of our result is 6. 
Result so far: 19926.0
If we subtract 4608 from 4839, we get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Going ahead to step 9:
768 goes into 2310 3 times with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 19926.3
Subtract 2304 from 2310 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
768 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 19926.3
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
If we divide 600 by 768, we get 0 and a remainder of 600.
The next digit of our result is 0. 
Result so far: 19926.3
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

After the division, we end up with 19926.3 and a remainder of 0.06.
