561530 divided by 19 
The aim is to understand the frequency of 19 in 561530.

Advancing to step 1:
When dividing 5 by 19, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 19

On to step 2:
If we divide 56 by 19, we get 2 and a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 38 away from 56, we end up with 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 19

Moving on to step 3:
When dividing 181 by 19, we get 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtract 171 from 181 to get 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 19

Advancing to step 4:
When dividing 105 by 19, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 295.0
If we take 95 away from 105, we end up with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 19

Advancing to step 5:
19 goes into 103 5 times with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 2955.0
Subtract 95 from 103 to get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 19

Step 6:
19 goes into 80 4 times with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 29554.0
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 7:
When dividing 40 by 19, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 29554.2
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.

Moving on to step 8:
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: 29554.21
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.

Step 9:
19 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 29554.21
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.

Let's proceed to step 10:
The number 19 fits into 100 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 29554.2105
Subtract 95 from 100 to 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.

Moving on to step 11:
When dividing 50 by 19, we get 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 29554.21052
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.

Let's proceed to step 12:
If we divide 120 by 19, we get 6 and a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 29554.210526
If we take 114 away from 120, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
19 can be fit into 60 3 times, resulting in a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 29554.2105263
Subtracting 57 from 60 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 14:
19 can be fit into 30 1 times, resulting in a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 29554.21052631
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.

The final outcome is 29554.21052631, with a leftover of 1.1e-08.
