510492 ÷ 19 
The aim is to understand the frequency of 19 in 510492.

Moving on to step 1:
When dividing 5 by 19, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 19

On to step 2:
19 can be fit into 51 2 times, resulting in a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 13 after subtracting 38 from 51.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 19

Going ahead to step 3:
When dividing 130 by 19, we get 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
Subtract 114 from 130 to get 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 19

Advancing to step 4:
164 divided by 19 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 268.0
Subtract 152 from 164 to get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 19

Advancing to step 5:
129 divided by 19 is 6 with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 2686.0
Subtracting 114 from 129 leaves us with 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 19

Step 6:
19 can be fit into 152 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 26868.0
The remainder is 0 after subtracting 152 from 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
19 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 26868.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 19 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 26868.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 26868.0, with a leftover of 0.0.
