We're dividing 78840992 by 966 
We're looking to find how many times 966 goes into 78840992.

Advancing to step 1:
When dividing 7 by 966, we get 0 with 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.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 966

Advancing to step 2:
When dividing 78 by 966, we get 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Include the next digit (8) from the dividend after 78, then repeat: 788 / 966

On to step 3:
966 goes into 788 0 times with a remainder of 788.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 788 leaves us with 788.
Include the next digit (4) from the dividend after 788, then repeat: 7884 / 966

Advancing to step 4:
When dividing 7884 by 966, we get 8 with a remainder of 156.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 156 after subtracting 7728 from 7884.
Bring next digit (0) of the dividend behind the 156 and repeat the process: 1560 / 966

Let's proceed to step 5:
966 goes into 1560 1 times with a remainder of 594.
The next digit of our result is 1. 
Result so far: 81.0
Subtract 966 from 1560 to get 594.
Grab the next digit (9) from the dividend, add it to 594, then carry on: 5949 / 966

Advancing to step 6:
When dividing 5949 by 966, we get 6 with a remainder of 153.
Put 6 as the next digit of the answer. 
Result so far: 816.0
The remainder is 153 after subtracting 5796 from 5949.
Take the next digit (9) from the dividend and append it to 153, then repeat: 1539 / 966

Step 7:
The number 966 fits into 1539 1 times, leaving a remainder of 573.
Write down 1 as next digit of the result. 
Result so far: 8161.0
If we take 966 away from 1539, we end up with 573.
Take the next digit (2) from the dividend and append it to 573, then repeat: 5732 / 966

Moving on to step 8:
966 can be fit into 5732 5 times, resulting in a remainder of 902.
The number 5 becomes the next digit in our result. 
Result so far: 81615.0
If we subtract 4830 from 5732, we get 902.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9020, and continue the process.

On to step 9:
966 can be fit into 9020 9 times, resulting in a remainder of 326.
Put 9 as the next digit of the answer. 
Result so far: 81615.9
If we take 8694 away from 9020, we end up with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Let's proceed to step 10:
The number 966 fits into 3260 3 times, leaving a remainder of 362.
Record the quotient 3 as the next digit in the result. 
Result so far: 81615.93
If we subtract 2898 from 3260, we get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Advancing to step 11:
966 goes into 3620 3 times with a remainder of 722.
The number 3 becomes the next digit in our result. 
Result so far: 81615.933
Deduct 2898 from 3620 and we're left with 722.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7220, and continue the process.

After the division, we end up with 81615.933 and a remainder of 0.0722.
