The number 960 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 960

Step 2:
When dividing 77 by 960, we get 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Grab the next digit (8) from the dividend, add it to 77, then carry on: 778 / 960

Moving on to step 3:
When dividing 778 by 960, we get 0 with a remainder of 778.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 778 leaves us with 778.
Take the next digit (1) from the dividend and append it to 778, then repeat: 7781 / 960

Advancing to step 4:
960 can be fit into 7781 8 times, resulting in a remainder of 101.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 7680 from 7781 to get 101.
Grab the next digit (5) from the dividend, add it to 101, then carry on: 1015 / 960

Step 5:
960 can be fit into 1015 1 times, resulting in a remainder of 55.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
Subtract 960 from 1015 to get 55.
Append the next digit (8) from the dividend to 55 and continue with: 558 / 960

Going ahead to step 6:
960 goes into 558 0 times with a remainder of 558.
Record the quotient 0 as the next digit in the result. 
Result so far: 810.0
The remainder is 558 after subtracting 0 from 558.
Take the next digit (8) from the dividend and append it to 558, then repeat: 5588 / 960

Let's proceed to step 7:
If we divide 5588 by 960, we get 5 and a remainder of 788.
The next digit of our result is 5. 
Result so far: 8105.0
The remainder is 788 after subtracting 4800 from 5588.
Append the next digit (1) from the dividend to 788 and continue with: 7881 / 960

Step 8:
7881 divided by 960 is 8 with a remainder of 201.
Put 8 as the next digit of the answer. 
Result so far: 81058.0
Subtract 7680 from 7881 to get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

On to step 9:
The number 960 fits into 2010 2 times, leaving a remainder of 90.
The next digit of our result is 2. 
Result so far: 81058.2
Subtract 1920 from 2010 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 10:
If we divide 900 by 960, we get 0 and a remainder of 900.
Put 0 as the next digit of the answer. 
Result so far: 81058.2
If we take 0 away from 900, we end up with 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

Going ahead to step 11:
9000 divided by 960 is 9 with a remainder of 360.
Put 9 as the next digit of the answer. 
Result so far: 81058.209
The remainder is 360 after subtracting 8640 from 9000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 12:
960 goes into 3600 3 times with a remainder of 720.
Write down 3 as next digit of the result. 
Result so far: 81058.2093
Subtract 2880 from 3600 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.

Going ahead to step 13:
7200 divided by 960 is 7 with a remainder of 480.
The next digit of our result is 7. 
Result so far: 81058.20937
If we subtract 6720 from 7200, we 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.

Let's proceed to step 14:
If we divide 4800 by 960, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 81058.209375
Deduct 4800 from 4800 and we're left 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:
If we divide 0 by 960, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 81058.209375
Deduct 0 from 0 and we're left 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.

Let's proceed to step 16:
960 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 81058.209375
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.

After the division, we end up with 81058.209375 and a remainder of 0.0.
