If we take 0 away from 5, we end up with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 966

On to step 2:
966 goes into 57 0 times with a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Fetch the next digit (8) from the dividend, attach it to 57 and continue: 578 / 966

Moving on to step 3:
966 goes into 578 0 times with a remainder of 578.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 578 to get 578.

Let's proceed to step 4:
966 can be fit into 5785 5 times, resulting in a remainder of 955.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 4830 from 5785 to get 955.
Take the next digit (4) from the dividend and append it to 955, then repeat: 9554 / 966

Step 5:
When dividing 9554 by 966, we get 9 with a remainder of 860.
Write down 9 as next digit of the result. 
Result so far: 59.0
If we take 8694 away from 9554, we end up with 860.
Include the next digit (8) from the dividend after 860, then repeat: 8608 / 966

Advancing to step 6:
966 goes into 8608 8 times with a remainder of 880.
Put 8 as the next digit of the answer. 
Result so far: 598.0
Subtracting 7728 from 8608 leaves us with 880.
Include the next digit (9) from the dividend after 880, then repeat: 8809 / 966

Moving on to step 7:
If we divide 8809 by 966, we get 9 and a remainder of 115.
Record the quotient 9 as the next digit in the result. 
Result so far: 5989.0
Deduct 8694 from 8809 and we're left with 115.
Grab the next digit (0) from the dividend, add it to 115, then carry on: 1150 / 966

Advancing to step 8:
When dividing 1150 by 966, we get 1 with a remainder of 184.
The next digit of our result is 1. 
Result so far: 59891.0
Subtract 966 from 1150 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 9:
If we divide 1840 by 966, we get 1 and a remainder of 874.
The next digit of our result is 1. 
Result so far: 59891.1
If we take 966 away from 1840, we end up with 874.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8740, and continue the process.

On to step 10:
When dividing 8740 by 966, we get 9 with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 59891.19
If we subtract 8694 from 8740, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 11:
460 divided by 966 is 0 with a remainder of 460.
Record the quotient 0 as the next digit in the result. 
Result so far: 59891.19
Deduct 0 from 460 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 12:
When dividing 4600 by 966, we get 4 with a remainder of 736.
The next digit of our result is 4. 
Result so far: 59891.1904
Subtracting 3864 from 4600 leaves us with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Let's proceed to step 13:
7360 divided by 966 is 7 with a remainder of 598.
Write down 7 as next digit of the result. 
Result so far: 59891.19047
If we subtract 6762 from 7360, we get 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Going ahead to step 14:
966 can be fit into 5980 6 times, resulting in a remainder of 184.
The next digit of our result is 6. 
Result so far: 59891.190476
Subtract 5796 from 5980 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 15:
966 can be fit into 1840 1 times, resulting in a remainder of 874.
The next digit of our result is 1. 
Result so far: 59891.1904761
Deduct 966 from 1840 and we're left with 874.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8740, and continue the process.

Going ahead to step 16:
966 goes into 8740 9 times with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 59891.19047619
If we subtract 8694 from 8740, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final result is 59891.19047619 with a remainder of 4.6e-08.
