285087 ÷ 19 
The aim is to understand the frequency of 19 in 285087.

Going ahead to step 1:
If we divide 2 by 19, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 19

Going ahead to step 2:
When dividing 28 by 19, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 19 from 28 to get 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 19

Advancing to step 3:
If we divide 95 by 19, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 95 from 95 and we're left with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 19

Going ahead to step 4:
The number 19 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 150.0
Subtracting 0 from 0 leaves us with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 19

On to step 5:
The number 19 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 1500.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 19

Going ahead to step 6:
19 goes into 87 4 times with a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 15004.0
If we subtract 76 from 87, 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.

Let's proceed to step 7:
When dividing 110 by 19, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 15004.5
If we take 95 away from 110, we end up 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.

Let's proceed to step 8:
When dividing 150 by 19, we get 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 15004.57
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.

Moving on to step 9:
19 goes into 170 8 times with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 15004.578
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.

On to step 10:
180 divided by 19 is 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 15004.5789
If we subtract 171 from 180, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
If we divide 90 by 19, we get 4 and a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 15004.57894
Subtracting 76 from 90 leaves us 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.

Going ahead to step 12:
If we divide 140 by 19, we get 7 and a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 15004.578947
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 13:
70 divided by 19 is 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 15004.5789473
If we take 57 away from 70, we end up 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 14:
The number 19 fits into 130 6 times, leaving a remainder of 16.
The next digit of our result is 6. 
Result so far: 15004.57894736
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.

The final outcome is 15004.57894736, with a leftover of 1.6e-08.
