We look at the division of 584372 by 19 
The aim is to understand the frequency of 19 in 584372.

Step 1:
The number 19 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 19

On to step 2:
19 goes into 58 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 1 after subtracting 57 from 58.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 19

Moving on to step 3:
19 goes into 14 0 times with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we subtract 0 from 14, we get 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 19

Let's proceed to step 4:
When dividing 143 by 19, we get 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 307.0
Deduct 133 from 143 and we're left with 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 19

On to step 5:
If we divide 107 by 19, we get 5 and a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 3075.0
If we subtract 95 from 107, we get 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 19

Step 6:
122 divided by 19 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 30756.0
Subtracting 114 from 122 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.

On to step 7:
19 goes into 80 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 30756.4
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.

On to step 8:
19 can be fit into 40 2 times, resulting in a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 30756.42
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.

Step 9:
When dividing 20 by 19, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 30756.421
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 10:
If we divide 10 by 19, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 30756.421
Subtracting 0 from 10 leaves us with 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 11:
The number 19 fits into 100 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 30756.42105
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.

On to step 12:
50 divided by 19 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 30756.421052
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.

Moving on to step 13:
19 can be fit into 120 6 times, resulting in a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 30756.4210526
Subtract 114 from 120 to get 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 14:
If we divide 60 by 19, we get 3 and a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 30756.42105263
Deduct 57 from 60 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 30756.42105263 with a remainder of 3e-09.
