We look at the division of 763920 by 15 
We want to divide 763920 by 15.

Step 1:
When dividing 7 by 15, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 15

Moving on to step 2:
The number 15 fits into 76 5 times, leaving a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 1 after subtracting 75 from 76.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 15

Let's proceed to step 3:
The number 15 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
Subtracting 0 from 13 leaves us with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 15

On to step 4:
When dividing 139 by 15, we get 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 509.0
Deduct 135 from 139 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 15

Moving on to step 5:
42 divided by 15 is 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 5092.0
Subtracting 30 from 42 leaves us with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 15

Moving on to step 6:
When dividing 120 by 15, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 50928.0
The remainder is 0 after subtracting 120 from 120.
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 7:
15 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 50928.0
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.

On to step 8:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 50928.0
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.

In conclusion, the division gives 50928.0 with a balance of 0.0.
