641250 ÷ 82 
The aim is to understand the frequency of 82 in 641250.

Step 1:
The number 82 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 82

Let's proceed to step 2:
82 goes into 64 0 times with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Fetch the next digit (1) from the dividend, attach it to 64 and continue: 641 / 82

Advancing to step 3:
If we divide 641 by 82, we get 7 and a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 574 from 641, we get 67.
Fetch the next digit (2) from the dividend, attach it to 67 and continue: 672 / 82

Let's proceed to step 4:
82 can be fit into 672 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 78.0
The remainder is 16 after subtracting 656 from 672.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 82

Let's proceed to step 5:
82 goes into 165 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 782.0
Subtracting 164 from 165 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 82

Going ahead to step 6:
If we divide 10 by 82, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 7820.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
If we divide 100 by 82, we get 1 and a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 7820.1
If we subtract 82 from 100, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
82 goes into 180 2 times with a remainder of 16.
The next digit of our result is 2. 
Result so far: 7820.12
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 9:
The number 82 fits into 160 1 times, leaving a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 7820.121
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.

On to step 10:
If we divide 780 by 82, we get 9 and a remainder of 42.
Record the quotient 9 as the next digit in the result. 
Result so far: 7820.1219
Subtracting 738 from 780 leaves us 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.

Moving on to step 11:
420 divided by 82 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 7820.12195
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.

On to step 12:
When dividing 100 by 82, we get 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 7820.121951
Subtract 82 from 100 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 13:
82 can be fit into 180 2 times, resulting in a remainder of 16.
The next digit of our result is 2. 
Result so far: 7820.1219512
Deduct 164 from 180 and we're left 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.

Step 14:
If we divide 160 by 82, we get 1 and a remainder of 78.
Use 1 as the next digit of our solution. 
Result so far: 7820.12195121
If we subtract 82 from 160, we get 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 7820.12195121, with a leftover of 7.8e-08.
