844072 ÷ 19 
The aim is to understand the frequency of 19 in 844072.

Let's proceed to step 1:
When dividing 8 by 19, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 19

Advancing to step 2:
19 can be fit into 84 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 76 from 84 to get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 19

On to step 3:
19 goes into 84 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 44.0
The remainder is 8 after subtracting 76 from 84.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 19

Advancing to step 4:
19 goes into 80 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 444.0
The remainder is 4 after subtracting 76 from 80.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 19

On to step 5:
If we divide 47 by 19, we get 2 and a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 4442.0
Deduct 38 from 47 and we're left with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 19

Moving on to step 6:
19 goes into 92 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 44424.0
Subtracting 76 from 92 leaves us with 16.
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 7:
The number 19 fits into 160 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 44424.8
Deduct 152 from 160 and we're left 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.

Moving on to step 8:
19 can be fit into 80 4 times, resulting in a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 44424.84
Subtracting 76 from 80 leaves us with 4.
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 9:
If we divide 40 by 19, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 44424.842
If we subtract 38 from 40, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
The number 19 fits into 20 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 44424.8421
Subtract 19 from 20 to get 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 11:
19 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 44424.8421
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.

On to step 12:
If we divide 100 by 19, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 44424.842105
The remainder is 5 after subtracting 95 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
19 can be fit into 50 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 44424.8421052
If we take 38 away from 50, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 14:
19 can be fit into 120 6 times, resulting in a remainder of 6.
The next digit of our result is 6. 
Result so far: 44424.84210526
If we take 114 away from 120, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 44424.84210526 with a remainder of 6e-09.
