We look at the division of 209585 by 19 
The aim is to understand the frequency of 19 in 209585.

Moving on to step 1:
If we divide 2 by 19, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 19

Let's proceed to step 2:
When dividing 20 by 19, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 19 from 20 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 19

Step 3:
19 goes into 19 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 0 after subtracting 19 from 19.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 19

Step 4:
The number 19 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
If we subtract 0 from 5, we get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 19

Step 5:
19 goes into 58 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 1103.0
The remainder is 1 after subtracting 57 from 58.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 19

On to step 6:
If we divide 15 by 19, we get 0 and a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 11030.0
The remainder is 15 after subtracting 0 from 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
When dividing 150 by 19, we get 7 with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 11030.7
If we take 133 away from 150, we end up 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.

Let's proceed to step 8:
19 can be fit into 170 8 times, resulting in a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 11030.78
The remainder is 18 after subtracting 152 from 170.
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 9:
If we divide 180 by 19, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 11030.789
Deduct 171 from 180 and we're left 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.

Going ahead to step 10:
If we divide 90 by 19, we get 4 and a remainder of 14.
The next digit of our result is 4. 
Result so far: 11030.7894
Deduct 76 from 90 and we're left with 14.
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 11:
The number 19 fits into 140 7 times, leaving a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 11030.78947
Deduct 133 from 140 and we're left 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 12:
19 goes into 70 3 times with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 11030.789473
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.

Advancing to step 13:
130 divided by 19 is 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 11030.7894736
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.

Advancing to step 14:
When dividing 160 by 19, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 11030.78947368
If we take 152 away from 160, we end up 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.

The final result is 11030.78947368 with a remainder of 8e-09.
