We're dividing 653515 by 19 
The aim is to understand the frequency of 19 in 653515.

Step 1:
The number 19 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 19

Going ahead to step 2:
65 divided by 19 is 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 8 after subtracting 57 from 65.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 19

Step 3:
83 divided by 19 is 4 with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
The remainder is 7 after subtracting 76 from 83.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 19

On to step 4:
19 can be fit into 75 3 times, resulting in a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 343.0
Subtracting 57 from 75 leaves us with 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 19

Step 5:
The number 19 fits into 181 9 times, leaving a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 3439.0
If we subtract 171 from 181, we get 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 19

Going ahead to step 6:
19 goes into 105 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 34395.0
If we take 95 away from 105, 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.

Step 7:
100 divided by 19 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 34395.5
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.

Let's proceed to step 8:
The number 19 fits into 50 2 times, leaving a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 34395.52
The remainder is 12 after subtracting 38 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
19 can be fit into 120 6 times, resulting in a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 34395.526
The remainder is 6 after subtracting 114 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
The number 19 fits into 60 3 times, leaving a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 34395.5263
Subtract 57 from 60 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 11:
If we divide 30 by 19, we get 1 and a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 34395.52631
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.

Advancing to step 12:
110 divided by 19 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 34395.526315
Deduct 95 from 110 and we're left 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:
If we divide 150 by 19, we get 7 and a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 34395.5263157
Deduct 133 from 150 and we're left 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.

On to step 14:
The number 19 fits into 170 8 times, leaving a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 34395.52631578
If we take 152 away from 170, we end up with 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 34395.52631578 and a remainder of 1.8e-08.
