We divide 452209 by 19
The aim is to understand the frequency of 19 in 452209.

Advancing to step 1:
19 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 19

Step 2:
When dividing 45 by 19, we get 2 with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 38 from 45 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 19

Let's proceed to step 3:
If we divide 72 by 19, we get 3 and a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
The remainder is 15 after subtracting 57 from 72.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 19

On to step 4:
When dividing 152 by 19, we get 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 238.0
Subtract 152 from 152 to get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 19

Step 5:
If we divide 0 by 19, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 2380.0
Deduct 0 from 0 and we're left with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 19

Step 6:
If we divide 9 by 19, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 23800.0
Subtracting 0 from 9 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.

Advancing to step 7:
When dividing 90 by 19, we get 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 23800.4
Subtract 76 from 90 to 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.

Advancing to step 8:
140 divided by 19 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 23800.47
If we subtract 133 from 140, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
The number 19 fits into 70 3 times, leaving a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 23800.473
If we subtract 57 from 70, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 10:
19 can be fit into 130 6 times, resulting in a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 23800.4736
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 11:
If we divide 160 by 19, we get 8 and a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 23800.47368
Subtracting 152 from 160 leaves us 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.

Step 12:
If we divide 80 by 19, we get 4 and a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 23800.473684
If we subtract 76 from 80, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
The number 19 fits into 40 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 23800.4736842
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.

On to step 14:
The number 19 fits into 20 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 23800.47368421
If we subtract 19 from 20, we 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.

After the division, we end up with 23800.47368421 and a remainder of 1e-09.
