8431509 ÷ 960 
We want to figure out the number of times 8431509 can be divided by 960.

Let's proceed to step 1:
If we divide 8 by 960, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 960

Going ahead to step 2:
960 goes into 84 0 times with a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Fetch the next digit (3) from the dividend, attach it to 84 and continue: 843 / 960

Step 3:
If we divide 843 by 960, we get 0 and a remainder of 843.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 843 to get 843.
Include the next digit (1) from the dividend after 843, then repeat: 8431 / 960

Moving on to step 4:
8431 divided by 960 is 8 with a remainder of 751.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 751 after subtracting 7680 from 8431.
Take the next digit (5) from the dividend and append it to 751, then repeat: 7515 / 960

Advancing to step 5:
7515 divided by 960 is 7 with a remainder of 795.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
If we take 6720 away from 7515, we end up with 795.
Append the next digit (0) from the dividend to 795 and continue with: 7950 / 960

Step 6:
When dividing 7950 by 960, we get 8 with a remainder of 270.
Put 8 as the next digit of the answer. 
Result so far: 878.0
If we subtract 7680 from 7950, we get 270.
Fetch the next digit (9) from the dividend, attach it to 270 and continue: 2709 / 960

Let's proceed to step 7:
When dividing 2709 by 960, we get 2 with a remainder of 789.
The number 2 becomes the next digit in our result. 
Result so far: 8782.0
If we subtract 1920 from 2709, we get 789.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7890, and continue the process.

Going ahead to step 8:
7890 divided by 960 is 8 with a remainder of 210.
Write down 8 as next digit of the result. 
Result so far: 8782.8
Subtract 7680 from 7890 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 9:
When dividing 2100 by 960, we get 2 with a remainder of 180.
Put 2 as the next digit of the answer. 
Result so far: 8782.82
Subtract 1920 from 2100 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 10:
The number 960 fits into 1800 1 times, leaving a remainder of 840.
Put 1 as the next digit of the answer. 
Result so far: 8782.821
Subtracting 960 from 1800 leaves us with 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Step 11:
960 goes into 8400 8 times with a remainder of 720.
Record the quotient 8 as the next digit in the result. 
Result so far: 8782.8218
Subtract 7680 from 8400 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Moving on to step 12:
If we divide 7200 by 960, we get 7 and a remainder of 480.
Use 7 as the next digit of our solution. 
Result so far: 8782.82187
Subtract 6720 from 7200 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 13:
960 goes into 4800 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 8782.821875
The remainder is 0 after subtracting 4800 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 14:
If we divide 0 by 960, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8782.821875
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.

Advancing to step 15:
When dividing 0 by 960, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8782.821875
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.

In conclusion, the division gives 8782.821875 with a balance of 0.0.
