312508 divided by 19 
The aim is to understand the frequency of 19 in 312508.

On to step 1:
3 divided by 19 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 19

Moving on to step 2:
19 can be fit into 31 1 times, resulting in a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 19 from 31, we get 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 19

Going ahead to step 3:
19 goes into 122 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 114 from 122, we get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 19

Let's proceed to step 4:
19 goes into 85 4 times with a remainder of 9.
The next digit of our result is 4. 
Result so far: 164.0
If we take 76 away from 85, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 19

Going ahead to step 5:
When dividing 90 by 19, we get 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 1644.0
Subtracting 76 from 90 leaves us with 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 19

Going ahead to step 6:
19 can be fit into 148 7 times, resulting in a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 16447.0
The remainder is 15 after subtracting 133 from 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
When dividing 150 by 19, we get 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 16447.7
The remainder is 17 after subtracting 133 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 8:
19 can be fit into 170 8 times, resulting in a remainder of 18.
The next digit of our result is 8. 
Result so far: 16447.78
Subtracting 152 from 170 leaves us 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.

Let's proceed to step 9:
When dividing 180 by 19, we get 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 16447.789
Deduct 171 from 180 and we're left 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 10:
90 divided by 19 is 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 16447.7894
If we take 76 away from 90, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 11:
If we divide 140 by 19, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 16447.78947
Subtracting 133 from 140 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 12:
The number 19 fits into 70 3 times, leaving a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 16447.789473
Subtracting 57 from 70 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 13:
When dividing 130 by 19, we get 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 16447.7894736
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.

Let's proceed to step 14:
19 can be fit into 160 8 times, resulting in a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 16447.78947368
Subtracting 152 from 160 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.

In conclusion, the division gives 16447.78947368 with a balance of 8e-09.
