131728 ÷ 19 
The aim is to understand the frequency of 19 in 131728.

Advancing to step 1:
1 divided by 19 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 19

On to step 2:
When dividing 13 by 19, we get 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 19

Moving on to step 3:
131 divided by 19 is 6 with a remainder of 17.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 114 from 131, we get 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 19

Moving on to step 4:
177 divided by 19 is 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 69.0
If we take 171 away from 177, we end up with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 19

Advancing to step 5:
62 divided by 19 is 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 693.0
Subtract 57 from 62 to get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 19

Moving on to step 6:
58 divided by 19 is 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 6933.0
The remainder is 1 after subtracting 57 from 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
If we divide 10 by 19, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 6933.0
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.

Going ahead to step 8:
19 goes into 100 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 6933.05
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.

Moving on to step 9:
19 goes into 50 2 times with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 6933.052
Subtract 38 from 50 to get 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 10:
If we divide 120 by 19, we get 6 and a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 6933.0526
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 11:
If we divide 60 by 19, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 6933.05263
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.

Going ahead to step 12:
If we divide 30 by 19, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 6933.052631
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.

On to step 13:
19 goes into 110 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 6933.0526315
The remainder is 15 after subtracting 95 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 14:
If we divide 150 by 19, we get 7 and a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 6933.05263157
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.

The final result is 6933.05263157 with a remainder of 1.7e-08.
