606399 divided by 19 
The aim is to understand the frequency of 19 in 606399.

Moving on to step 1:
If we divide 6 by 19, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 19

Going ahead to step 2:
When dividing 60 by 19, we get 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 3 after subtracting 57 from 60.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 19

Moving on to step 3:
The number 19 fits into 36 1 times, leaving a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Deduct 19 from 36 and we're left with 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 19

Let's proceed to step 4:
19 can be fit into 173 9 times, resulting in a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 319.0
Subtract 171 from 173 to get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 19

On to step 5:
When dividing 29 by 19, we get 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 3191.0
If we subtract 19 from 29, we get 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 19

Advancing to step 6:
If we divide 109 by 19, we get 5 and a remainder of 14.
The next digit of our result is 5. 
Result so far: 31915.0
The remainder is 14 after subtracting 95 from 109.
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 7:
If we divide 140 by 19, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 31915.7
Subtracting 133 from 140 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 8:
19 goes into 70 3 times with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 31915.73
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.

Step 9:
130 divided by 19 is 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 31915.736
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 10:
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: 31915.7368
Subtract 152 from 160 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
When dividing 80 by 19, we get 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 31915.73684
Subtracting 76 from 80 leaves us 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 12:
19 can be fit into 40 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 31915.736842
The remainder is 2 after subtracting 38 from 40.
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 13:
20 divided by 19 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 31915.7368421
Subtracting 19 from 20 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 14:
19 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 31915.7368421
If we take 0 away from 10, we end up 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.

Our division results in 31915.7368421 with a remaining 1e-08.
