365899 divided by 19 
The aim is to understand the frequency of 19 in 365899.

Moving on to step 1:
If we divide 3 by 19, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 19

Advancing to step 2:
19 can be fit into 36 1 times, resulting in a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 17 after subtracting 19 from 36.
Bring next digit (5) of the dividend behind the 17 and repeat the process: 175 / 19

Step 3:
When dividing 175 by 19, we get 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtracting 171 from 175 leaves us with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 19

Moving on to step 4:
19 can be fit into 48 2 times, resulting in a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 192.0
If we take 38 away from 48, we end up with 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 19

Let's proceed to step 5:
19 goes into 109 5 times with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 1925.0
If we take 95 away from 109, we end up with 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 19

On to step 6:
When dividing 149 by 19, we get 7 with a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 19257.0
If we subtract 133 from 149, we 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.

Advancing to step 7:
19 can be fit into 160 8 times, resulting in a remainder of 8.
The next digit of our result is 8. 
Result so far: 19257.8
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 8:
If we divide 80 by 19, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 19257.84
The remainder is 4 after subtracting 76 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
19 can be fit into 40 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 19257.842
Subtracting 38 from 40 leaves us 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.

Going ahead to step 10:
The number 19 fits into 20 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 19257.8421
Subtract 19 from 20 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 11:
19 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 19257.8421
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
When dividing 100 by 19, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 19257.842105
If we subtract 95 from 100, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 13:
19 can be fit into 50 2 times, resulting in a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 19257.8421052
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 14:
19 can be fit into 120 6 times, resulting in a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 19257.84210526
If we subtract 114 from 120, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 19257.84210526 and a remainder of 6e-09.
