We divide 561802 by 19
The aim is to understand the frequency of 19 in 561802.

Let's proceed to step 1:
If we divide 5 by 19, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 19

Step 2:
When dividing 56 by 19, we get 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 38 from 56 and we're left with 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 19

Going ahead to step 3:
181 divided by 19 is 9 with a remainder of 10.
The next digit of our result is 9. 
Result so far: 29.0
Subtract 171 from 181 to get 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 19

On to step 4:
108 divided by 19 is 5 with a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 295.0
Subtracting 95 from 108 leaves us with 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 19

Going ahead to step 5:
19 can be fit into 130 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 2956.0
Deduct 114 from 130 and we're left with 16.
Fetch the next digit (2) from the dividend, attach it to 16 and continue: 162 / 19

Step 6:
19 goes into 162 8 times with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 29568.0
If we take 152 away from 162, 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.

Advancing to step 7:
100 divided by 19 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 29568.5
The remainder is 5 after subtracting 95 from 100.
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 8:
50 divided by 19 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 29568.52
If we subtract 38 from 50, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
When dividing 120 by 19, we get 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 29568.526
Deduct 114 from 120 and we're left 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.

Let's proceed to step 10:
When dividing 60 by 19, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 29568.5263
If we take 57 away from 60, we end up 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.

Moving on to step 11:
30 divided by 19 is 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 29568.52631
Subtracting 19 from 30 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
110 divided by 19 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 29568.526315
The remainder is 15 after subtracting 95 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 13:
19 goes into 150 7 times with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 29568.5263157
Subtracting 133 from 150 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 14:
If we divide 170 by 19, we get 8 and a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 29568.52631578
If we subtract 152 from 170, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 29568.52631578 and a remainder of 1.8e-08.
