817892 divided by 19 
The aim is to understand the frequency of 19 in 817892.

Moving on to step 1:
19 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 19

Step 2:
19 goes into 81 4 times with a remainder of 5.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 76 from 81 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 19

Step 3:
57 divided by 19 is 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Subtracting 57 from 57 leaves us with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 19

Step 4:
When dividing 8 by 19, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 430.0
If we subtract 0 from 8, we get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 19

On to step 5:
89 divided by 19 is 4 with a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 4304.0
If we take 76 away from 89, we end up with 13.
Include the next digit (2) from the dividend after 13, then repeat: 132 / 19

On to step 6:
19 can be fit into 132 6 times, resulting in a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 43046.0
If we take 114 away from 132, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
19 can be fit into 180 9 times, resulting in a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 43046.9
If we take 171 away from 180, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 8:
The number 19 fits into 90 4 times, leaving a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 43046.94
Subtract 76 from 90 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
When dividing 140 by 19, we get 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 43046.947
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.

Going ahead to step 10:
If we divide 70 by 19, we get 3 and a remainder of 13.
The next digit of our result is 3. 
Result so far: 43046.9473
If we subtract 57 from 70, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 11:
The number 19 fits into 130 6 times, leaving a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 43046.94736
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.

On to step 12:
If we divide 160 by 19, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 43046.947368
If we take 152 away from 160, we end up 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.

Step 13:
80 divided by 19 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 43046.9473684
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 14:
40 divided by 19 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 43046.94736842
Subtracting 38 from 40 leaves us 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.

After the division, we end up with 43046.94736842 and a remainder of 2e-09.
