We're dividing 15688932 by 809 
The aim is to understand the frequency of 809 in 15688932.

Step 1:
1 divided by 809 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 809

Going ahead to step 2:
The number 809 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 809

Moving on to step 3:
156 divided by 809 is 0 with a remainder of 156.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 156 and we're left with 156.
Grab the next digit (8) from the dividend, add it to 156, then carry on: 1568 / 809

Advancing to step 4:
809 can be fit into 1568 1 times, resulting in a remainder of 759.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 809 from 1568 to get 759.
Append the next digit (8) from the dividend to 759 and continue with: 7598 / 809

Going ahead to step 5:
When dividing 7598 by 809, we get 9 with a remainder of 317.
Use 9 as the next digit of our solution. 
Result so far: 19.0
The remainder is 317 after subtracting 7281 from 7598.
Append the next digit (9) from the dividend to 317 and continue with: 3179 / 809

Step 6:
When dividing 3179 by 809, we get 3 with a remainder of 752.
The next digit of our result is 3. 
Result so far: 193.0
If we take 2427 away from 3179, we end up with 752.
Fetch the next digit (3) from the dividend, attach it to 752 and continue: 7523 / 809

Step 7:
7523 divided by 809 is 9 with a remainder of 242.
The number 9 becomes the next digit in our result. 
Result so far: 1939.0
The remainder is 242 after subtracting 7281 from 7523.
Bring next digit (2) of the dividend behind the 242 and repeat the process: 2422 / 809

Going ahead to step 8:
809 goes into 2422 2 times with a remainder of 804.
Record the quotient 2 as the next digit in the result. 
Result so far: 19392.0
Subtract 1618 from 2422 to get 804.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

Let's proceed to step 9:
809 can be fit into 8040 9 times, resulting in a remainder of 759.
The next digit of our result is 9. 
Result so far: 19392.9
Subtract 7281 from 8040 to get 759.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7590, and continue the process.

Step 10:
7590 divided by 809 is 9 with a remainder of 309.
Write down 9 as next digit of the result. 
Result so far: 19392.99
The remainder is 309 after subtracting 7281 from 7590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

In conclusion, the division gives 19392.99 with a balance of 0.309.
