874993 ÷ 19 
The aim is to understand the frequency of 19 in 874993.

Let's proceed to step 1:
When dividing 8 by 19, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 19

Going ahead to step 2:
19 goes into 87 4 times with a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 76 from 87 to get 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 19

On to step 3:
The number 19 fits into 114 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 46.0
Subtract 114 from 114 to get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 19

Moving on to step 4:
19 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 460.0
Subtract 0 from 9 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 19

Step 5:
99 divided by 19 is 5 with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 4605.0
Subtract 95 from 99 to get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 19

Step 6:
19 goes into 43 2 times with a remainder of 5.
The next digit of our result is 2. 
Result so far: 46052.0
If we take 38 away from 43, 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:
19 can be fit into 50 2 times, resulting in a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 46052.2
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.

Going ahead to step 8:
When dividing 120 by 19, we get 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 46052.26
Subtracting 114 from 120 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
If we divide 60 by 19, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 46052.263
The remainder is 3 after subtracting 57 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
If we divide 30 by 19, we get 1 and a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 46052.2631
Subtract 19 from 30 to 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.

Going ahead to step 11:
110 divided by 19 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 46052.26315
If we subtract 95 from 110, we get 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 12:
If we divide 150 by 19, we get 7 and a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 46052.263157
Subtract 133 from 150 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 13:
The number 19 fits into 170 8 times, leaving a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 46052.2631578
Deduct 152 from 170 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 14:
180 divided by 19 is 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 46052.26315789
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.

The quotient of the division is 46052.26315789, and the remainder is 9e-09.
