Let's divide 215318 by 19
The aim is to understand the frequency of 19 in 215318.

On to step 1:
19 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 19

Let's proceed to step 2:
The number 19 fits into 21 1 times, leaving a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 19 from 21 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 19

Let's proceed to step 3:
25 divided by 19 is 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 19 from 25 to get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 19

Going ahead to step 4:
If we divide 63 by 19, we get 3 and a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
Deduct 57 from 63 and we're left with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 19

Step 5:
61 divided by 19 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 1133.0
Subtracting 57 from 61 leaves us with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 19

Advancing to step 6:
The number 19 fits into 48 2 times, leaving a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 11332.0
The remainder is 10 after subtracting 38 from 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
The number 19 fits into 100 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 11332.5
Subtracting 95 from 100 leaves us with 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 8:
When dividing 50 by 19, we get 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 11332.52
Subtract 38 from 50 to 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.

On to step 9:
If we divide 120 by 19, we get 6 and a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 11332.526
Subtracting 114 from 120 leaves us 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.

On to step 10:
60 divided by 19 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 11332.5263
Deduct 57 from 60 and we're left 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 11:
30 divided by 19 is 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 11332.52631
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.

Moving on to step 12:
110 divided by 19 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 11332.526315
If we take 95 away from 110, we end up 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.

Step 13:
19 can be fit into 150 7 times, resulting in a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 11332.5263157
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:
The number 19 fits into 170 8 times, leaving a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 11332.52631578
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.

In conclusion, the division gives 11332.52631578 with a balance of 1.8e-08.
