15305732 ÷ 768 
We want to figure out the number of times 15305732 can be divided by 768.

Going ahead to step 1:
When dividing 1 by 768, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 768

Moving on to step 2:
15 divided by 768 is 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 768

Let's proceed to step 3:
When dividing 153 by 768, we get 0 with a remainder of 153.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 153 to get 153.
Bring next digit (0) of the dividend behind the 153 and repeat the process: 1530 / 768

Going ahead to step 4:
768 can be fit into 1530 1 times, resulting in a remainder of 762.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 768 from 1530 to get 762.
Fetch the next digit (5) from the dividend, attach it to 762 and continue: 7625 / 768

Step 5:
The number 768 fits into 7625 9 times, leaving a remainder of 713.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we subtract 6912 from 7625, we get 713.
Bring next digit (7) of the dividend behind the 713 and repeat the process: 7137 / 768

Advancing to step 6:
768 can be fit into 7137 9 times, resulting in a remainder of 225.
Write down 9 as next digit of the result. 
Result so far: 199.0
Subtracting 6912 from 7137 leaves us with 225.
Bring next digit (3) of the dividend behind the 225 and repeat the process: 2253 / 768

On to step 7:
2253 divided by 768 is 2 with a remainder of 717.
Write down 2 as next digit of the result. 
Result so far: 1992.0
The remainder is 717 after subtracting 1536 from 2253.
Fetch the next digit (2) from the dividend, attach it to 717 and continue: 7172 / 768

On to step 8:
The number 768 fits into 7172 9 times, leaving a remainder of 260.
Write down 9 as next digit of the result. 
Result so far: 19929.0
Subtracting 6912 from 7172 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 9:
768 goes into 2600 3 times with a remainder of 296.
Record the quotient 3 as the next digit in the result. 
Result so far: 19929.3
Subtracting 2304 from 2600 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 10:
The number 768 fits into 2960 3 times, leaving a remainder of 656.
Put 3 as the next digit of the answer. 
Result so far: 19929.33
Subtracting 2304 from 2960 leaves us with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

The quotient of the division is 19929.33, and the remainder is 0.656.
