We divide 85866964 by 966
We want to divide 85866964 by 966.

Advancing to step 1:
If we divide 8 by 966, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 966

Let's proceed to step 2:
85 divided by 966 is 0 with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Take the next digit (8) from the dividend and append it to 85, then repeat: 858 / 966

Advancing to step 3:
The number 966 fits into 858 0 times, leaving a remainder of 858.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 858, we end up with 858.
Take the next digit (6) from the dividend and append it to 858, then repeat: 8586 / 966

Step 4:
If we divide 8586 by 966, we get 8 and a remainder of 858.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 7728 from 8586 leaves us with 858.
Bring next digit (6) of the dividend behind the 858 and repeat the process: 8586 / 966

Step 5:
966 can be fit into 8586 8 times, resulting in a remainder of 858.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
If we subtract 7728 from 8586, we get 858.
Take the next digit (9) from the dividend and append it to 858, then repeat: 8589 / 966

Step 6:
The number 966 fits into 8589 8 times, leaving a remainder of 861.
Use 8 as the next digit of our solution. 
Result so far: 888.0
Subtract 7728 from 8589 to get 861.
Fetch the next digit (6) from the dividend, attach it to 861 and continue: 8616 / 966

On to step 7:
The number 966 fits into 8616 8 times, leaving a remainder of 888.
Record the quotient 8 as the next digit in the result. 
Result so far: 8888.0
Subtracting 7728 from 8616 leaves us with 888.
Append the next digit (4) from the dividend to 888 and continue with: 8884 / 966

Moving on to step 8:
966 goes into 8884 9 times with a remainder of 190.
Put 9 as the next digit of the answer. 
Result so far: 88889.0
Subtract 8694 from 8884 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 9:
If we divide 1900 by 966, we get 1 and a remainder of 934.
Write down 1 as next digit of the result. 
Result so far: 88889.1
Deduct 966 from 1900 and we're left with 934.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9340, and continue the process.

Advancing to step 10:
9340 divided by 966 is 9 with a remainder of 646.
The next digit of our result is 9. 
Result so far: 88889.19
The remainder is 646 after subtracting 8694 from 9340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Going ahead to step 11:
The number 966 fits into 6460 6 times, leaving a remainder of 664.
Use 6 as the next digit of our solution. 
Result so far: 88889.196
Subtract 5796 from 6460 to get 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Let's proceed to step 12:
6640 divided by 966 is 6 with a remainder of 844.
The number 6 becomes the next digit in our result. 
Result so far: 88889.1966
Subtract 5796 from 6640 to get 844.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

The final result is 88889.1966 with a remainder of 0.00844.
