81282031 ÷ 966 
The aim is to understand the frequency of 966 in 81282031.

Advancing to 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.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 966

Advancing to step 2:
966 can be fit into 81 0 times, resulting in a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Fetch the next digit (2) from the dividend, attach it to 81 and continue: 812 / 966

Advancing to step 3:
812 divided by 966 is 0 with a remainder of 812.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 812 after subtracting 0 from 812.
Fetch the next digit (8) from the dividend, attach it to 812 and continue: 8128 / 966

Step 4:
If we divide 8128 by 966, we get 8 and a remainder of 400.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 7728 away from 8128, we end up with 400.
Include the next digit (2) from the dividend after 400, then repeat: 4002 / 966

Advancing to step 5:
If we divide 4002 by 966, we get 4 and a remainder of 138.
Write down 4 as next digit of the result. 
Result so far: 84.0
Subtract 3864 from 4002 to get 138.
Take the next digit (0) from the dividend and append it to 138, then repeat: 1380 / 966

Step 6:
966 can be fit into 1380 1 times, resulting in a remainder of 414.
Record the quotient 1 as the next digit in the result. 
Result so far: 841.0
Subtracting 966 from 1380 leaves us with 414.
Grab the next digit (3) from the dividend, add it to 414, then carry on: 4143 / 966

Advancing to step 7:
The number 966 fits into 4143 4 times, leaving a remainder of 279.
Record the quotient 4 as the next digit in the result. 
Result so far: 8414.0
Deduct 3864 from 4143 and we're left with 279.
Fetch the next digit (1) from the dividend, attach it to 279 and continue: 2791 / 966

Step 8:
966 can be fit into 2791 2 times, resulting in a remainder of 859.
The number 2 becomes the next digit in our result. 
Result so far: 84142.0
The remainder is 859 after subtracting 1932 from 2791.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8590, and continue the process.

Let's proceed to step 9:
The number 966 fits into 8590 8 times, leaving a remainder of 862.
Write down 8 as next digit of the result. 
Result so far: 84142.8
If we subtract 7728 from 8590, we get 862.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8620, and continue the process.

Step 10:
The number 966 fits into 8620 8 times, leaving a remainder of 892.
Use 8 as the next digit of our solution. 
Result so far: 84142.88
Deduct 7728 from 8620 and we're left with 892.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8920, and continue the process.

The final outcome is 84142.88, with a leftover of 0.892.
