We're dividing 77648709 by 966 
Our goal is to divide 77648709 by 966.

Advancing to step 1:
966 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 966

Step 2:
When dividing 77 by 966, we get 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Fetch the next digit (6) from the dividend, attach it to 77 and continue: 776 / 966

Advancing to step 3:
966 can be fit into 776 0 times, resulting in a remainder of 776.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 776 to get 776.
Bring next digit (4) of the dividend behind the 776 and repeat the process: 7764 / 966

On to step 4:
7764 divided by 966 is 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 7728 from 7764 to get 36.
Grab the next digit (8) from the dividend, add it to 36, then carry on: 368 / 966

Advancing to step 5:
The number 966 fits into 368 0 times, leaving a remainder of 368.
Use 0 as the next digit of our solution. 
Result so far: 80.0
If we take 0 away from 368, we end up with 368.
Include the next digit (7) from the dividend after 368, then repeat: 3687 / 966

Let's proceed to step 6:
When dividing 3687 by 966, we get 3 with a remainder of 789.
Use 3 as the next digit of our solution. 
Result so far: 803.0
If we take 2898 away from 3687, we end up with 789.
Append the next digit (0) from the dividend to 789 and continue with: 7890 / 966

Advancing to step 7:
7890 divided by 966 is 8 with a remainder of 162.
The number 8 becomes the next digit in our result. 
Result so far: 8038.0
Subtract 7728 from 7890 to get 162.
Grab the next digit (9) from the dividend, add it to 162, then carry on: 1629 / 966

Step 8:
When dividing 1629 by 966, we get 1 with a remainder of 663.
Use 1 as the next digit of our solution. 
Result so far: 80381.0
If we subtract 966 from 1629, we get 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

Moving on to step 9:
966 can be fit into 6630 6 times, resulting in a remainder of 834.
The number 6 becomes the next digit in our result. 
Result so far: 80381.6
The remainder is 834 after subtracting 5796 from 6630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

Let's proceed to step 10:
966 goes into 8340 8 times with a remainder of 612.
Put 8 as the next digit of the answer. 
Result so far: 80381.68
Subtract 7728 from 8340 to get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Let's proceed to step 11:
When dividing 6120 by 966, we get 6 with a remainder of 324.
Record the quotient 6 as the next digit in the result. 
Result so far: 80381.686
Subtract 5796 from 6120 to get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Let's proceed to step 12:
The number 966 fits into 3240 3 times, leaving a remainder of 342.
Write down 3 as next digit of the result. 
Result so far: 80381.6863
Subtracting 2898 from 3240 leaves us with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Moving on to step 13:
The number 966 fits into 3420 3 times, leaving a remainder of 522.
Record the quotient 3 as the next digit in the result. 
Result so far: 80381.68633
If we subtract 2898 from 3420, we get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Our division results in 80381.68633 with a remaining 0.000522.
