501485 ÷ 19 
The aim is to understand the frequency of 19 in 501485.

On to step 1:
5 divided by 19 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 19

Going ahead to step 2:
50 divided by 19 is 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 2.0
If we take 38 away from 50, we end up with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 19

Moving on to step 3:
If we divide 121 by 19, we get 6 and a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Deduct 114 from 121 and we're left with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 19

Moving on to step 4:
19 goes into 74 3 times with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 263.0
The remainder is 17 after subtracting 57 from 74.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 19

Going ahead to step 5:
19 goes into 178 9 times with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 2639.0
If we take 171 away from 178, we end up with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 19

Let's proceed to step 6:
When dividing 75 by 19, we get 3 with a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 26393.0
Subtract 57 from 75 to get 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 7:
If we divide 180 by 19, we get 9 and a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 26393.9
Subtracting 171 from 180 leaves us 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 8:
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: 26393.94
The remainder is 14 after subtracting 76 from 90.
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 9:
140 divided by 19 is 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 26393.947
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.

Going ahead to step 10:
19 goes into 70 3 times with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 26393.9473
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.

Moving on to step 11:
When dividing 130 by 19, we get 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 26393.94736
Subtract 114 from 130 to 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.

Going ahead to step 12:
19 goes into 160 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 26393.947368
Deduct 152 from 160 and we're left 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.

Advancing to step 13:
19 goes into 80 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 26393.9473684
If we take 76 away from 80, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
When dividing 40 by 19, we get 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 26393.94736842
Deduct 38 from 40 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 26393.94736842 and a remainder of 2e-09.
