We're dividing 14988243 by 809 
The aim is to understand the frequency of 809 in 14988243.

Let's proceed to step 1:
If we divide 1 by 809, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 809

Moving on to step 2:
The number 809 fits into 14 0 times, leaving a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 809

Let's proceed to step 3:
When dividing 149 by 809, we get 0 with a remainder of 149.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 149 and we're left with 149.
Append the next digit (8) from the dividend to 149 and continue with: 1498 / 809

Advancing to step 4:
When dividing 1498 by 809, we get 1 with a remainder of 689.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 809 from 1498 and we're left with 689.
Bring next digit (8) of the dividend behind the 689 and repeat the process: 6898 / 809

Going ahead to step 5:
809 can be fit into 6898 8 times, resulting in a remainder of 426.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 6472 from 6898 and we're left with 426.
Grab the next digit (2) from the dividend, add it to 426, then carry on: 4262 / 809

Step 6:
If we divide 4262 by 809, we get 5 and a remainder of 217.
Write down 5 as next digit of the result. 
Result so far: 185.0
If we take 4045 away from 4262, we end up with 217.
Grab the next digit (4) from the dividend, add it to 217, then carry on: 2174 / 809

Moving on to step 7:
When dividing 2174 by 809, we get 2 with a remainder of 556.
Write down 2 as next digit of the result. 
Result so far: 1852.0
Subtracting 1618 from 2174 leaves us with 556.
Bring next digit (3) of the dividend behind the 556 and repeat the process: 5563 / 809

Moving on to step 8:
5563 divided by 809 is 6 with a remainder of 709.
Write down 6 as next digit of the result. 
Result so far: 18526.0
Deduct 4854 from 5563 and we're left with 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

Let's proceed to step 9:
If we divide 7090 by 809, we get 8 and a remainder of 618.
Write down 8 as next digit of the result. 
Result so far: 18526.8
If we take 6472 away from 7090, we end up with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Advancing to step 10:
6180 divided by 809 is 7 with a remainder of 517.
Write down 7 as next digit of the result. 
Result so far: 18526.87
If we take 5663 away from 6180, we end up with 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Let's proceed to step 11:
When dividing 5170 by 809, we get 6 with a remainder of 316.
The number 6 becomes the next digit in our result. 
Result so far: 18526.876
If we subtract 4854 from 5170, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 12:
If we divide 3160 by 809, we get 3 and a remainder of 733.
Write down 3 as next digit of the result. 
Result so far: 18526.8763
The remainder is 733 after subtracting 2427 from 3160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7330, and continue the process.

Advancing to step 13:
When dividing 7330 by 809, we get 9 with a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 18526.87639
If we subtract 7281 from 7330, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 14:
The number 809 fits into 490 0 times, leaving a remainder of 490.
Write down 0 as next digit of the result. 
Result so far: 18526.87639
If we take 0 away from 490, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Going ahead to step 15:
809 goes into 4900 6 times with a remainder of 46.
The next digit of our result is 6. 
Result so far: 18526.8763906
Subtracting 4854 from 4900 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 16:
When dividing 460 by 809, we get 0 with a remainder of 460.
Put 0 as the next digit of the answer. 
Result so far: 18526.8763906
The remainder is 460 after subtracting 0 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

The final result is 18526.8763906 with a remainder of 4.6e-07.
