80566435 ÷ 966 
We're looking to find how many times 966 goes into 80566435.

Step 1:
966 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 966

Advancing to step 2:
The number 966 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Append the next digit (5) from the dividend to 80 and continue with: 805 / 966

Moving on to step 3:
The number 966 fits into 805 0 times, leaving a remainder of 805.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 805 to get 805.
Take the next digit (6) from the dividend and append it to 805, then repeat: 8056 / 966

Advancing to step 4:
966 goes into 8056 8 times with a remainder of 328.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 7728 from 8056 and we're left with 328.
Include the next digit (6) from the dividend after 328, then repeat: 3286 / 966

Moving on to step 5:
The number 966 fits into 3286 3 times, leaving a remainder of 388.
Use 3 as the next digit of our solution. 
Result so far: 83.0
The remainder is 388 after subtracting 2898 from 3286.
Include the next digit (4) from the dividend after 388, then repeat: 3884 / 966

Step 6:
966 can be fit into 3884 4 times, resulting in a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 834.0
Subtract 3864 from 3884 to get 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 966

Going ahead to step 7:
203 divided by 966 is 0 with a remainder of 203.
The number 0 becomes the next digit in our result. 
Result so far: 8340.0
If we subtract 0 from 203, we get 203.
Bring next digit (5) of the dividend behind the 203 and repeat the process: 2035 / 966

Going ahead to step 8:
When dividing 2035 by 966, we get 2 with a remainder of 103.
The next digit of our result is 2. 
Result so far: 83402.0
If we take 1932 away from 2035, we end up with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 9:
The number 966 fits into 1030 1 times, leaving a remainder of 64.
Record the quotient 1 as the next digit in the result. 
Result so far: 83402.1
If we subtract 966 from 1030, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
When dividing 640 by 966, we get 0 with a remainder of 640.
The next digit of our result is 0. 
Result so far: 83402.1
If we take 0 away from 640, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 11:
966 goes into 6400 6 times with a remainder of 604.
The number 6 becomes the next digit in our result. 
Result so far: 83402.106
If we take 5796 away from 6400, we end up with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Going ahead to step 12:
966 can be fit into 6040 6 times, resulting in a remainder of 244.
The number 6 becomes the next digit in our result. 
Result so far: 83402.1066
If we take 5796 away from 6040, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

After the division, we end up with 83402.1066 and a remainder of 0.00244.
