We're dividing 452089 by 19 
The aim is to understand the frequency of 19 in 452089.

Going ahead to step 1:
4 divided by 19 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 19

On to step 2:
45 divided by 19 is 2 with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 7 after subtracting 38 from 45.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 19

Advancing to step 3:
19 can be fit into 72 3 times, resulting in a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtracting 57 from 72 leaves us with 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 19

Step 4:
19 goes into 150 7 times with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 237.0
Subtracting 133 from 150 leaves us with 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 19

Step 5:
The number 19 fits into 178 9 times, leaving a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 2379.0
Subtract 171 from 178 to get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 19

Step 6:
If we divide 79 by 19, we get 4 and a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 23794.0
Subtracting 76 from 79 leaves us 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.

Step 7:
19 goes into 30 1 times with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 23794.1
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.

Advancing to step 8:
The number 19 fits into 110 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 23794.15
Deduct 95 from 110 and we're left with 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 9:
150 divided by 19 is 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 23794.157
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.

Moving on to step 10:
When dividing 170 by 19, we get 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 23794.1578
Deduct 152 from 170 and we're left 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 11:
19 goes into 180 9 times with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 23794.15789
Subtracting 171 from 180 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.

On to step 12:
When dividing 90 by 19, we get 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 23794.157894
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.

Let's proceed to step 13:
When dividing 140 by 19, we get 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 23794.1578947
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.

Moving on to step 14:
The number 19 fits into 70 3 times, leaving a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 23794.15789473
Deduct 57 from 70 and we're left 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.

In conclusion, the division gives 23794.15789473 with a balance of 1.3e-08.
