285877 divided by 19 
The aim is to understand the frequency of 19 in 285877.

Advancing to step 1:
When dividing 2 by 19, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 19

Let's proceed to step 2:
19 can be fit into 28 1 times, resulting in a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 19 from 28 to get 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 19

Moving on to step 3:
If we divide 95 by 19, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 0 after subtracting 95 from 95.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 19

Moving on to step 4:
The number 19 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 150.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 19

Moving on to step 5:
87 divided by 19 is 4 with a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 1504.0
Subtract 76 from 87 to get 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 19

Step 6:
19 can be fit into 117 6 times, resulting in a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 15046.0
The remainder is 3 after subtracting 114 from 117.
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 7:
The number 19 fits into 30 1 times, leaving a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 15046.1
If we take 19 away from 30, we end up 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.

On to step 8:
110 divided by 19 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 15046.15
Deduct 95 from 110 and we're left 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.

Step 9:
150 divided by 19 is 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 15046.157
Subtracting 133 from 150 leaves us 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.

On to step 10:
When dividing 170 by 19, we get 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 15046.1578
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.

Going ahead to step 11:
19 can be fit into 180 9 times, resulting in a remainder of 9.
The next digit of our result is 9. 
Result so far: 15046.15789
If we take 171 away from 180, we end up 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.

Moving on to step 12:
If we divide 90 by 19, we get 4 and a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 15046.157894
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.

Moving on to step 13:
140 divided by 19 is 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 15046.1578947
The remainder is 7 after subtracting 133 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 14:
When dividing 70 by 19, we get 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 15046.15789473
If we subtract 57 from 70, we 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.

The quotient of the division is 15046.15789473, and the remainder is 1.3e-08.
