We look at the division of 86523569 by 960 
We want to figure out the number of times 86523569 can be divided by 960.

Let's proceed to step 1:
960 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 960

Advancing to step 2:
If we divide 86 by 960, we get 0 and a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Take the next digit (5) from the dividend and append it to 86, then repeat: 865 / 960

Step 3:
960 goes into 865 0 times with a remainder of 865.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 865, we get 865.
Append the next digit (2) from the dividend to 865 and continue with: 8652 / 960

Let's proceed to step 4:
When dividing 8652 by 960, we get 9 with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 12 after subtracting 8640 from 8652.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 960

Moving on to step 5:
When dividing 123 by 960, we get 0 with a remainder of 123.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Subtracting 0 from 123 leaves us with 123.
Grab the next digit (5) from the dividend, add it to 123, then carry on: 1235 / 960

Let's proceed to step 6:
960 goes into 1235 1 times with a remainder of 275.
The number 1 becomes the next digit in our result. 
Result so far: 901.0
If we take 960 away from 1235, we end up with 275.
Append the next digit (6) from the dividend to 275 and continue with: 2756 / 960

Going ahead to step 7:
960 can be fit into 2756 2 times, resulting in a remainder of 836.
The next digit of our result is 2. 
Result so far: 9012.0
If we subtract 1920 from 2756, we get 836.
Grab the next digit (9) from the dividend, add it to 836, then carry on: 8369 / 960

Advancing to step 8:
The number 960 fits into 8369 8 times, leaving a remainder of 689.
The next digit of our result is 8. 
Result so far: 90128.0
Subtracting 7680 from 8369 leaves us with 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

Moving on to step 9:
When dividing 6890 by 960, we get 7 with a remainder of 170.
Write down 7 as next digit of the result. 
Result so far: 90128.7
Deduct 6720 from 6890 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 10:
1700 divided by 960 is 1 with a remainder of 740.
Write down 1 as next digit of the result. 
Result so far: 90128.71
If we take 960 away from 1700, we end up with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Let's proceed to step 11:
960 goes into 7400 7 times with a remainder of 680.
Use 7 as the next digit of our solution. 
Result so far: 90128.717
If we subtract 6720 from 7400, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Moving on to step 12:
When dividing 6800 by 960, we get 7 with a remainder of 80.
Use 7 as the next digit of our solution. 
Result so far: 90128.7177
Subtract 6720 from 6800 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 90128.7177 with a remainder of 0.0008.
