We look at the division of 76176439 by 966 
Let's see how many times 966 fits into 76176439.

Advancing to step 1:
966 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 966

Going ahead to step 2:
When dividing 76 by 966, we get 0 with a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Bring next digit (1) of the dividend behind the 76 and repeat the process: 761 / 966

Advancing to step 3:
966 goes into 761 0 times with a remainder of 761.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 761 to get 761.
Include the next digit (7) from the dividend after 761, then repeat: 7617 / 966

Moving on to step 4:
If we divide 7617 by 966, we get 7 and a remainder of 855.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 6762 away from 7617, we end up with 855.
Grab the next digit (6) from the dividend, add it to 855, then carry on: 8556 / 966

Moving on to step 5:
If we divide 8556 by 966, we get 8 and a remainder of 828.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Subtracting 7728 from 8556 leaves us with 828.
Fetch the next digit (4) from the dividend, attach it to 828 and continue: 8284 / 966

Moving on to step 6:
966 goes into 8284 8 times with a remainder of 556.
The number 8 becomes the next digit in our result. 
Result so far: 788.0
Subtract 7728 from 8284 to get 556.
Fetch the next digit (3) from the dividend, attach it to 556 and continue: 5563 / 966

Let's proceed to step 7:
966 goes into 5563 5 times with a remainder of 733.
Use 5 as the next digit of our solution. 
Result so far: 7885.0
If we subtract 4830 from 5563, we get 733.
Include the next digit (9) from the dividend after 733, then repeat: 7339 / 966

Advancing to step 8:
966 goes into 7339 7 times with a remainder of 577.
Write down 7 as next digit of the result. 
Result so far: 78857.0
If we subtract 6762 from 7339, we get 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

On to step 9:
966 goes into 5770 5 times with a remainder of 940.
Write down 5 as next digit of the result. 
Result so far: 78857.5
Subtracting 4830 from 5770 leaves us with 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9400, and continue the process.

On to step 10:
The number 966 fits into 9400 9 times, leaving a remainder of 706.
The next digit of our result is 9. 
Result so far: 78857.59
Subtract 8694 from 9400 to get 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Moving on to step 11:
If we divide 7060 by 966, we get 7 and a remainder of 298.
Record the quotient 7 as the next digit in the result. 
Result so far: 78857.597
Deduct 6762 from 7060 and we're left with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Let's proceed to step 12:
2980 divided by 966 is 3 with a remainder of 82.
Put 3 as the next digit of the answer. 
Result so far: 78857.5973
The remainder is 82 after subtracting 2898 from 2980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 13:
966 goes into 820 0 times with a remainder of 820.
The next digit of our result is 0. 
Result so far: 78857.5973
The remainder is 820 after subtracting 0 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

On to step 14:
966 can be fit into 8200 8 times, resulting in a remainder of 472.
The number 8 becomes the next digit in our result. 
Result so far: 78857.597308
If we take 7728 away from 8200, we end up with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Let's proceed to step 15:
When dividing 4720 by 966, we get 4 with a remainder of 856.
The number 4 becomes the next digit in our result. 
Result so far: 78857.5973084
If we subtract 3864 from 4720, we get 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

Advancing to step 16:
966 goes into 8560 8 times with a remainder of 832.
The next digit of our result is 8. 
Result so far: 78857.59730848
If we take 7728 away from 8560, we end up with 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

The final result is 78857.59730848 with a remainder of 8.32e-07.
