We look at the division of 823120 by 19 
The aim is to understand the frequency of 19 in 823120.

Step 1:
If we divide 8 by 19, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 19

Advancing to step 2:
When dividing 82 by 19, we get 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 76 from 82 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 19

Advancing to step 3:
63 divided by 19 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Deduct 57 from 63 and we're left with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 19

Step 4:
19 goes into 61 3 times with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 433.0
Deduct 57 from 61 and we're left with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 19

Let's proceed to step 5:
The number 19 fits into 42 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 4332.0
If we subtract 38 from 42, we get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 19

Step 6:
When dividing 40 by 19, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 43322.0
The remainder is 2 after subtracting 38 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
19 goes into 20 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 43322.1
Subtracting 19 from 20 leaves us 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.

Let's proceed to step 8:
19 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 43322.1
Subtract 0 from 10 to 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.

Let's proceed to step 9:
19 can be fit into 100 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 43322.105
Deduct 95 from 100 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
The number 19 fits into 50 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 43322.1052
Subtracting 38 from 50 leaves us 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.

Let's proceed to step 11:
The number 19 fits into 120 6 times, leaving a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 43322.10526
Deduct 114 from 120 and we're left 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.

Moving on to step 12:
The number 19 fits into 60 3 times, leaving a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 43322.105263
If we subtract 57 from 60, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
19 can be fit into 30 1 times, resulting in a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 43322.1052631
If we subtract 19 from 30, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 14:
If we divide 110 by 19, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 43322.10526315
If we take 95 away from 110, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 43322.10526315 with a balance of 1.5e-08.
