We're dividing 80622039 by 966 
We want to divide 80622039 by 966.

Let's proceed to step 1:
When dividing 8 by 966, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 966

Advancing to step 2:
The number 966 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Grab the next digit (6) from the dividend, add it to 80, then carry on: 806 / 966

Moving on to step 3:
The number 966 fits into 806 0 times, leaving a remainder of 806.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 806, we get 806.
Include the next digit (2) from the dividend after 806, then repeat: 8062 / 966

Going ahead to step 4:
966 goes into 8062 8 times with a remainder of 334.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 7728 from 8062 to get 334.
Bring next digit (2) of the dividend behind the 334 and repeat the process: 3342 / 966

Let's proceed to step 5:
If we divide 3342 by 966, we get 3 and a remainder of 444.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
Subtract 2898 from 3342 to get 444.
Append the next digit (0) from the dividend to 444 and continue with: 4440 / 966

Advancing to step 6:
966 can be fit into 4440 4 times, resulting in a remainder of 576.
The number 4 becomes the next digit in our result. 
Result so far: 834.0
Subtracting 3864 from 4440 leaves us with 576.
Bring next digit (3) of the dividend behind the 576 and repeat the process: 5763 / 966

Going ahead to step 7:
966 can be fit into 5763 5 times, resulting in a remainder of 933.
Put 5 as the next digit of the answer. 
Result so far: 8345.0
Subtract 4830 from 5763 to get 933.
Bring next digit (9) of the dividend behind the 933 and repeat the process: 9339 / 966

Advancing to step 8:
966 goes into 9339 9 times with a remainder of 645.
Use 9 as the next digit of our solution. 
Result so far: 83459.0
The remainder is 645 after subtracting 8694 from 9339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

On to step 9:
966 can be fit into 6450 6 times, resulting in a remainder of 654.
The next digit of our result is 6. 
Result so far: 83459.6
The remainder is 654 after subtracting 5796 from 6450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Moving on to step 10:
When dividing 6540 by 966, we get 6 with a remainder of 744.
Use 6 as the next digit of our solution. 
Result so far: 83459.66
Deduct 5796 from 6540 and we're left with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

The final result is 83459.66 with a remainder of 0.744.
