Let's divide 209754 by 19
The aim is to understand the frequency of 19 in 209754.

Step 1:
The number 19 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 19

On to step 2:
19 can be fit into 20 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 19 from 20 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 19

Going ahead to step 3:
If we divide 19 by 19, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 19 from 19 and we're left with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 19

On to step 4:
19 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 110.0
If we subtract 0 from 7, we get 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 19

Let's proceed to step 5:
When dividing 75 by 19, we get 3 with a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 1103.0
Deduct 57 from 75 and we're left with 18.
Fetch the next digit (4) from the dividend, attach it to 18 and continue: 184 / 19

Step 6:
If we divide 184 by 19, we get 9 and a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 11039.0
Subtracting 171 from 184 leaves us 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.

Let's proceed to step 7:
130 divided by 19 is 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 11039.6
If we subtract 114 from 130, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
The number 19 fits into 160 8 times, leaving a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 11039.68
Subtract 152 from 160 to get 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 9:
80 divided by 19 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 11039.684
If we take 76 away from 80, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
If we divide 40 by 19, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 11039.6842
Subtract 38 from 40 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
The number 19 fits into 20 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 11039.68421
Deduct 19 from 20 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 12:
The number 19 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 11039.68421
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
100 divided by 19 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 11039.6842105
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.

On to step 14:
If we divide 50 by 19, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 11039.68421052
If we take 38 away from 50, we end up 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.

The quotient of the division is 11039.68421052, and the remainder is 1.2e-08.
