We divide 78456 by 19
The aim is to understand the frequency of 19 in 78456.

Advancing to step 1:
19 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 19

Advancing to step 2:
78 divided by 19 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 76 from 78, we get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 19

Going ahead to step 3:
19 goes into 24 1 times with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 41.0
If we subtract 19 from 24, we get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 19

Moving on to step 4:
If we divide 55 by 19, we get 2 and a remainder of 17.
The next digit of our result is 2. 
Result so far: 412.0
If we take 38 away from 55, we end up with 17.
Append the next digit (6) from the dividend to 17 and continue with: 176 / 19

Advancing to step 5:
When dividing 176 by 19, we get 9 with a remainder of 5.
The next digit of our result is 9. 
Result so far: 4129.0
If we take 171 away from 176, 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 6:
When dividing 50 by 19, we get 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 4129.2
Subtracting 38 from 50 leaves us 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.

Moving on to step 7:
If we divide 120 by 19, we get 6 and a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 4129.26
The remainder is 6 after subtracting 114 from 120.
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 8:
If we divide 60 by 19, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 4129.263
Deduct 57 from 60 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
The number 19 fits into 30 1 times, leaving a remainder of 11.
The next digit of our result is 1. 
Result so far: 4129.2631
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.

Step 10:
If we divide 110 by 19, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 4129.26315
Subtract 95 from 110 to 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.

On to step 11:
The number 19 fits into 150 7 times, leaving a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 4129.263157
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 12:
19 can be fit into 170 8 times, resulting in a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 4129.2631578
If we take 152 away from 170, we end up 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 13:
If we divide 180 by 19, we get 9 and a remainder of 9.
The next digit of our result is 9. 
Result so far: 4129.26315789
If we take 171 away from 180, we end up 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 4129.26315789, and the remainder is 9e-09.
