443 divided by 82 
The aim is to understand the frequency of 82 in 443.

Step 1:
4 divided by 82 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 82

On to step 2:
The number 82 fits into 44 0 times, leaving a remainder of 44.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 44 and we're left with 44.
Grab the next digit (3) from the dividend, add it to 44, then carry on: 443 / 82

Moving on to step 3:
When dividing 443 by 82, we get 5 with a remainder of 33.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 410 from 443 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 4:
82 goes into 330 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 5.4
If we subtract 328 from 330, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 5:
When dividing 20 by 82, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 5.4
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 6:
If we divide 200 by 82, we get 2 and a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 5.402
Deduct 164 from 200 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 7:
If we divide 360 by 82, we get 4 and a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 5.4024
If we take 328 away from 360, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 8:
82 can be fit into 320 3 times, resulting in a remainder of 74.
The next digit of our result is 3. 
Result so far: 5.40243
Subtracting 246 from 320 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 9:
82 goes into 740 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 5.402439
Deduct 738 from 740 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
82 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 5.402439
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
When dividing 200 by 82, we get 2 with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 5.40243902
If we subtract 164 from 200, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 5.40243902, with a leftover of 3.6e-08.
