873843 ÷ 82 
The aim is to understand the frequency of 82 in 873843.

On to step 1:
8 divided by 82 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 82

Advancing to step 2:
87 divided by 82 is 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 82 away from 87, we end up with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 82

Going ahead to step 3:
When dividing 53 by 82, we get 0 with a remainder of 53.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 53 after subtracting 0 from 53.
Append the next digit (8) from the dividend to 53 and continue with: 538 / 82

On to step 4:
When dividing 538 by 82, we get 6 with a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
The remainder is 46 after subtracting 492 from 538.
Grab the next digit (4) from the dividend, add it to 46, then carry on: 464 / 82

Advancing to step 5:
When dividing 464 by 82, we get 5 with a remainder of 54.
Record the quotient 5 as the next digit in the result. 
Result so far: 1065.0
The remainder is 54 after subtracting 410 from 464.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 82

On to step 6:
When dividing 543 by 82, we get 6 with a remainder of 51.
Use 6 as the next digit of our solution. 
Result so far: 10656.0
The remainder is 51 after subtracting 492 from 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 7:
The number 82 fits into 510 6 times, leaving a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 10656.6
If we take 492 away from 510, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
82 goes into 180 2 times with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 10656.62
Subtract 164 from 180 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
82 goes into 160 1 times with a remainder of 78.
Record the quotient 1 as the next digit in the result. 
Result so far: 10656.621
The remainder is 78 after subtracting 82 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 10:
780 divided by 82 is 9 with a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 10656.6219
If we take 738 away from 780, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 11:
82 goes into 420 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 10656.62195
If we take 410 away from 420, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
If we divide 100 by 82, we get 1 and a remainder of 18.
The next digit of our result is 1. 
Result so far: 10656.621951
Subtracting 82 from 100 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 13:
82 can be fit into 180 2 times, resulting in a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 10656.6219512
If we take 164 away from 180, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
The number 82 fits into 160 1 times, leaving a remainder of 78.
Use 1 as the next digit of our solution. 
Result so far: 10656.62195121
Subtracting 82 from 160 leaves us 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.

The final outcome is 10656.62195121, with a leftover of 7.8e-08.
