15223 divided by 82 
The aim is to understand the frequency of 82 in 15223.

Going ahead to step 1:
1 divided by 82 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 82

Moving on to step 2:
When dividing 15 by 82, we get 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 82

Step 3:
The number 82 fits into 152 1 times, leaving a remainder of 70.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 82 from 152, we get 70.
Include the next digit (2) from the dividend after 70, then repeat: 702 / 82

Step 4:
82 goes into 702 8 times with a remainder of 46.
The next digit of our result is 8. 
Result so far: 18.0
Subtract 656 from 702 to get 46.
Bring next digit (3) of the dividend behind the 46 and repeat the process: 463 / 82

Let's proceed to step 5:
If we divide 463 by 82, we get 5 and a remainder of 53.
Record the quotient 5 as the next digit in the result. 
Result so far: 185.0
The remainder is 53 after subtracting 410 from 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 6:
530 divided by 82 is 6 with a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 185.6
The remainder is 38 after subtracting 492 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 7:
The number 82 fits into 380 4 times, leaving a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 185.64
If we subtract 328 from 380, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 8:
When dividing 520 by 82, we get 6 with a remainder of 28.
The next digit of our result is 6. 
Result so far: 185.646
Subtracting 492 from 520 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 9:
If we divide 280 by 82, we get 3 and a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 185.6463
Subtracting 246 from 280 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 10:
When dividing 340 by 82, we get 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 185.64634
Deduct 328 from 340 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
If we divide 120 by 82, we get 1 and a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 185.646341
If we take 82 away from 120, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 12:
When dividing 380 by 82, we get 4 with a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 185.6463414
Subtract 328 from 380 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 13:
82 can be fit into 520 6 times, resulting in a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 185.64634146
The remainder is 28 after subtracting 492 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 185.64634146 with a remainder of 2.8e-08.
