Let's divide 809243 by 19
The aim is to understand the frequency of 19 in 809243.

Going ahead to step 1:
When dividing 8 by 19, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 19

Advancing to step 2:
19 goes into 80 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 76 from 80 to get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 19

Advancing to step 3:
The number 19 fits into 49 2 times, leaving a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we subtract 38 from 49, we get 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 19

Going ahead to step 4:
When dividing 112 by 19, we get 5 with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 425.0
If we take 95 away from 112, we end up with 17.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 19

Let's proceed to step 5:
When dividing 174 by 19, we get 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 4259.0
If we take 171 away from 174, we end up with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 19

Let's proceed to step 6:
When dividing 33 by 19, we get 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 42591.0
The remainder is 14 after subtracting 19 from 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
19 goes into 140 7 times with a remainder of 7.
The next digit of our result is 7. 
Result so far: 42591.7
If we subtract 133 from 140, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 8:
If we divide 70 by 19, we get 3 and a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 42591.73
Subtracting 57 from 70 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
When dividing 130 by 19, we get 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 42591.736
The remainder is 16 after subtracting 114 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
19 goes into 160 8 times with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 42591.7368
Subtracting 152 from 160 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
19 goes into 80 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 42591.73684
The remainder is 4 after subtracting 76 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
40 divided by 19 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 42591.736842
If we take 38 away from 40, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
19 goes into 20 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 42591.7368421
Deduct 19 from 20 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 14:
10 divided by 19 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 42591.7368421
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.

In conclusion, the division gives 42591.7368421 with a balance of 1e-08.
