We're dividing 83123456 by 966 
Let's see how many times 966 fits into 83123456.

Step 1:
When dividing 8 by 966, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 966

Going ahead to step 2:
966 can be fit into 83 0 times, resulting in a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Include the next digit (1) from the dividend after 83, then repeat: 831 / 966

Advancing to step 3:
831 divided by 966 is 0 with a remainder of 831.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 831 after subtracting 0 from 831.
Include the next digit (2) from the dividend after 831, then repeat: 8312 / 966

Let's proceed to step 4:
The number 966 fits into 8312 8 times, leaving a remainder of 584.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 7728 from 8312 to get 584.
Take the next digit (3) from the dividend and append it to 584, then repeat: 5843 / 966

Going ahead to step 5:
966 goes into 5843 6 times with a remainder of 47.
Write down 6 as next digit of the result. 
Result so far: 86.0
If we subtract 5796 from 5843, we get 47.
Append the next digit (4) from the dividend to 47 and continue with: 474 / 966

On to step 6:
474 divided by 966 is 0 with a remainder of 474.
Use 0 as the next digit of our solution. 
Result so far: 860.0
Deduct 0 from 474 and we're left with 474.
Fetch the next digit (5) from the dividend, attach it to 474 and continue: 4745 / 966

On to step 7:
The number 966 fits into 4745 4 times, leaving a remainder of 881.
Record the quotient 4 as the next digit in the result. 
Result so far: 8604.0
The remainder is 881 after subtracting 3864 from 4745.
Include the next digit (6) from the dividend after 881, then repeat: 8816 / 966

Step 8:
If we divide 8816 by 966, we get 9 and a remainder of 122.
Record the quotient 9 as the next digit in the result. 
Result so far: 86049.0
Deduct 8694 from 8816 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 9:
966 goes into 1220 1 times with a remainder of 254.
Write down 1 as next digit of the result. 
Result so far: 86049.1
The remainder is 254 after subtracting 966 from 1220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

On to step 10:
If we divide 2540 by 966, we get 2 and a remainder of 608.
Use 2 as the next digit of our solution. 
Result so far: 86049.12
Deduct 1932 from 2540 and we're left with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

On to step 11:
If we divide 6080 by 966, we get 6 and a remainder of 284.
The number 6 becomes the next digit in our result. 
Result so far: 86049.126
Deduct 5796 from 6080 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Going ahead to step 12:
966 can be fit into 2840 2 times, resulting in a remainder of 908.
The number 2 becomes the next digit in our result. 
Result so far: 86049.1262
Subtracting 1932 from 2840 leaves us with 908.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9080, and continue the process.

Moving on to step 13:
9080 divided by 966 is 9 with a remainder of 386.
Record the quotient 9 as the next digit in the result. 
Result so far: 86049.12629
The remainder is 386 after subtracting 8694 from 9080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Let's proceed to step 14:
966 can be fit into 3860 3 times, resulting in a remainder of 962.
Use 3 as the next digit of our solution. 
Result so far: 86049.126293
If we take 2898 away from 3860, we end up with 962.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9620, and continue the process.

Let's proceed to step 15:
966 goes into 9620 9 times with a remainder of 926.
The number 9 becomes the next digit in our result. 
Result so far: 86049.1262939
Deduct 8694 from 9620 and we're left with 926.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9260, and continue the process.

Let's proceed to step 16:
966 can be fit into 9260 9 times, resulting in a remainder of 566.
Write down 9 as next digit of the result. 
Result so far: 86049.12629399
Subtract 8694 from 9260 to get 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

The quotient of the division is 86049.12629399, and the remainder is 5.66e-07.
