488516 divided by 19 
The aim is to understand the frequency of 19 in 488516.

Let's proceed to step 1:
If we divide 4 by 19, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 19

On to step 2:
19 can be fit into 48 2 times, resulting in a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 38 from 48 leaves us with 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 19

Going ahead to step 3:
108 divided by 19 is 5 with a remainder of 13.
The next digit of our result is 5. 
Result so far: 25.0
If we take 95 away from 108, we end up with 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 19

Step 4:
19 goes into 135 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 257.0
The remainder is 2 after subtracting 133 from 135.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 19

Let's proceed to step 5:
The number 19 fits into 21 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 2571.0
Subtracting 19 from 21 leaves us with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 19

Moving on to step 6:
If we divide 26 by 19, we get 1 and a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 25711.0
Subtract 19 from 26 to 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.

Let's proceed to step 7:
The number 19 fits into 70 3 times, leaving a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 25711.3
Subtract 57 from 70 to 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 8:
19 goes into 130 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 25711.36
If we subtract 114 from 130, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
160 divided by 19 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 25711.368
Subtract 152 from 160 to get 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 10:
When dividing 80 by 19, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 25711.3684
Deduct 76 from 80 and we're left 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.

Advancing to step 11:
When dividing 40 by 19, we get 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 25711.36842
Deduct 38 from 40 and we're left 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.

Let's proceed to step 12:
When dividing 20 by 19, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 25711.368421
If we take 19 away from 20, we end up 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.

Advancing to step 13:
10 divided by 19 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 25711.368421
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.

Moving on to step 14:
The number 19 fits into 100 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 25711.36842105
Subtract 95 from 100 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 25711.36842105 and a remainder of 5e-09.
