We're dividing 82409635 by 210 
The aim is to understand the frequency of 210 in 82409635.

Step 1:
If we divide 8 by 210, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 210

Step 2:
The number 210 fits into 82 0 times, leaving a remainder of 82.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 82 after subtracting 0 from 82.
Grab the next digit (4) from the dividend, add it to 82, then carry on: 824 / 210

Going ahead to step 3:
210 can be fit into 824 3 times, resulting in a remainder of 194.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 630 away from 824, we end up with 194.
Fetch the next digit (0) from the dividend, attach it to 194 and continue: 1940 / 210

Step 4:
210 can be fit into 1940 9 times, resulting in a remainder of 50.
Write down 9 as next digit of the result. 
Result so far: 39.0
If we take 1890 away from 1940, we end up with 50.
Append the next digit (9) from the dividend to 50 and continue with: 509 / 210

Moving on to step 5:
When dividing 509 by 210, we get 2 with a remainder of 89.
Use 2 as the next digit of our solution. 
Result so far: 392.0
The remainder is 89 after subtracting 420 from 509.
Take the next digit (6) from the dividend and append it to 89, then repeat: 896 / 210

Let's proceed to step 6:
210 can be fit into 896 4 times, resulting in a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 3924.0
The remainder is 56 after subtracting 840 from 896.
Take the next digit (3) from the dividend and append it to 56, then repeat: 563 / 210

Step 7:
563 divided by 210 is 2 with a remainder of 143.
Record the quotient 2 as the next digit in the result. 
Result so far: 39242.0
If we take 420 away from 563, we end up with 143.
Grab the next digit (5) from the dividend, add it to 143, then carry on: 1435 / 210

On to step 8:
The number 210 fits into 1435 6 times, leaving a remainder of 175.
Put 6 as the next digit of the answer. 
Result so far: 392426.0
Subtract 1260 from 1435 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 9:
1750 divided by 210 is 8 with a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 392426.8
Subtracting 1680 from 1750 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
700 divided by 210 is 3 with a remainder of 70.
Use 3 as the next digit of our solution. 
Result so far: 392426.83
If we take 630 away from 700, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 11:
The number 210 fits into 700 3 times, leaving a remainder of 70.
Record the quotient 3 as the next digit in the result. 
Result so far: 392426.833
If we subtract 630 from 700, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

In conclusion, the division gives 392426.833 with a balance of 0.007.
