879015 divided by 19 
The aim is to understand the frequency of 19 in 879015.

Going ahead to step 1:
If we divide 8 by 19, we get 0 and 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.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 19

Let's proceed to step 2:
87 divided by 19 is 4 with a remainder of 11.
The next digit of our result is 4. 
Result so far: 4.0
If we take 76 away from 87, we end up with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 19

Advancing to step 3:
The number 19 fits into 119 6 times, leaving a remainder of 5.
The next digit of our result is 6. 
Result so far: 46.0
If we take 114 away from 119, we end up with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 19

Advancing to step 4:
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: 462.0
Subtract 38 from 50 to get 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 19

Step 5:
The number 19 fits into 121 6 times, leaving a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 4626.0
The remainder is 7 after subtracting 114 from 121.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 19

On to step 6:
75 divided by 19 is 3 with a remainder of 18.
The next digit of our result is 3. 
Result so far: 46263.0
Subtracting 57 from 75 leaves us 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.

Step 7:
19 can be fit into 180 9 times, resulting in a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 46263.9
Deduct 171 from 180 and we're left 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.

On to step 8:
When dividing 90 by 19, we get 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 46263.94
If we subtract 76 from 90, we get 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 9:
If we divide 140 by 19, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 46263.947
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.

Advancing to step 10:
The number 19 fits into 70 3 times, leaving a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 46263.9473
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 11:
The number 19 fits into 130 6 times, leaving a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 46263.94736
If we take 114 away from 130, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
If we divide 160 by 19, we get 8 and a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 46263.947368
If we take 152 away from 160, we end up 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.

On to step 13:
80 divided by 19 is 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 46263.9473684
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.

Step 14:
The number 19 fits into 40 2 times, leaving a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 46263.94736842
If we take 38 away from 40, we end up 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.

The final outcome is 46263.94736842, with a leftover of 2e-09.
