209635 divided by 83 
The aim is to understand the frequency of 83 in 209635.

Advancing to step 1:
When dividing 2 by 83, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 83

Moving on to step 2:
If we divide 20 by 83, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 83

Going ahead to step 3:
209 divided by 83 is 2 with a remainder of 43.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 166 from 209 leaves us with 43.
Append the next digit (6) from the dividend to 43 and continue with: 436 / 83

On to step 4:
83 can be fit into 436 5 times, resulting in a remainder of 21.
Write down 5 as next digit of the result. 
Result so far: 25.0
Deduct 415 from 436 and we're left with 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 83

Let's proceed to step 5:
213 divided by 83 is 2 with a remainder of 47.
Use 2 as the next digit of our solution. 
Result so far: 252.0
Deduct 166 from 213 and we're left with 47.
Take the next digit (5) from the dividend and append it to 47, then repeat: 475 / 83

On to step 6:
83 can be fit into 475 5 times, resulting in a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 2525.0
If we take 415 away from 475, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 7:
83 goes into 600 7 times with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 2525.7
The remainder is 19 after subtracting 581 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 8:
83 goes into 190 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 2525.72
The remainder is 24 after subtracting 166 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
When dividing 240 by 83, we get 2 with a remainder of 74.
Record the quotient 2 as the next digit in the result. 
Result so far: 2525.722
Subtract 166 from 240 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

After the division, we end up with 2525.722 and a remainder of 0.0074.
