We're dividing 82073994 by 966 
The aim is to understand the frequency of 966 in 82073994.

Step 1:
8 divided by 966 is 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.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 966

On to step 2:
966 can be fit into 82 0 times, resulting in a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 82 to get 82.
Bring next digit (0) of the dividend behind the 82 and repeat the process: 820 / 966

Advancing to step 3:
966 goes into 820 0 times with a remainder of 820.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 820 after subtracting 0 from 820.
Fetch the next digit (7) from the dividend, attach it to 820 and continue: 8207 / 966

Step 4:
966 goes into 8207 8 times with a remainder of 479.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 479 after subtracting 7728 from 8207.
Fetch the next digit (3) from the dividend, attach it to 479 and continue: 4793 / 966

Going ahead to step 5:
966 goes into 4793 4 times with a remainder of 929.
The next digit of our result is 4. 
Result so far: 84.0
Deduct 3864 from 4793 and we're left with 929.
Bring next digit (9) of the dividend behind the 929 and repeat the process: 9299 / 966

Going ahead to step 6:
9299 divided by 966 is 9 with a remainder of 605.
Put 9 as the next digit of the answer. 
Result so far: 849.0
Deduct 8694 from 9299 and we're left with 605.
Fetch the next digit (9) from the dividend, attach it to 605 and continue: 6059 / 966

Step 7:
The number 966 fits into 6059 6 times, leaving a remainder of 263.
Use 6 as the next digit of our solution. 
Result so far: 8496.0
If we take 5796 away from 6059, we end up with 263.
Take the next digit (4) from the dividend and append it to 263, then repeat: 2634 / 966

Advancing to step 8:
If we divide 2634 by 966, we get 2 and a remainder of 702.
Use 2 as the next digit of our solution. 
Result so far: 84962.0
Subtracting 1932 from 2634 leaves us with 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Advancing to step 9:
966 can be fit into 7020 7 times, resulting in a remainder of 258.
The number 7 becomes the next digit in our result. 
Result so far: 84962.7
If we subtract 6762 from 7020, we get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 10:
If we divide 2580 by 966, we get 2 and a remainder of 648.
The next digit of our result is 2. 
Result so far: 84962.72
Subtracting 1932 from 2580 leaves us with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Going ahead to step 11:
The number 966 fits into 6480 6 times, leaving a remainder of 684.
Write down 6 as next digit of the result. 
Result so far: 84962.726
Subtract 5796 from 6480 to get 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Advancing to step 12:
If we divide 6840 by 966, we get 7 and a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 84962.7267
If we take 6762 away from 6840, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 13:
When dividing 780 by 966, we get 0 with a remainder of 780.
Write down 0 as next digit of the result. 
Result so far: 84962.7267
If we subtract 0 from 780, we get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Step 14:
If we divide 7800 by 966, we get 8 and a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 84962.726708
The remainder is 72 after subtracting 7728 from 7800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 15:
If we divide 720 by 966, we get 0 and a remainder of 720.
The next digit of our result is 0. 
Result so far: 84962.726708
Deduct 0 from 720 and we're left with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Let's proceed to step 16:
966 goes into 7200 7 times with a remainder of 438.
Record the quotient 7 as the next digit in the result. 
Result so far: 84962.72670807
Subtracting 6762 from 7200 leaves us with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

The final result is 84962.72670807 with a remainder of 4.38e-07.
