28757 divided by 19 
The aim is to understand the frequency of 19 in 28757.

Step 1:
19 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 19

Step 2:
If we divide 28 by 19, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 19 away from 28, we end up with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 19

Going ahead to step 3:
When dividing 97 by 19, we get 5 with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 95 from 97, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 19

Let's proceed to step 4:
25 divided by 19 is 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 151.0
If we subtract 19 from 25, we get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 19

Moving on to step 5:
When dividing 67 by 19, we get 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 1513.0
The remainder is 10 after subtracting 57 from 67.
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 6:
When dividing 100 by 19, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 1513.5
If we take 95 away from 100, we end up 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 7:
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: 1513.52
Deduct 38 from 50 and we're left 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.

Step 8:
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: 1513.526
The remainder is 6 after subtracting 114 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
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: 1513.5263
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.

Moving on to step 10:
If we divide 30 by 19, we get 1 and a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1513.52631
Subtracting 19 from 30 leaves us with 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 11:
If we divide 110 by 19, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 1513.526315
Subtracting 95 from 110 leaves us 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.

Going ahead to step 12:
150 divided by 19 is 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 1513.5263157
If we take 133 away from 150, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 13:
If we divide 170 by 19, we get 8 and a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 1513.52631578
The remainder is 18 after subtracting 152 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 1513.52631578, and the remainder is 1.8e-08.
