We're dividing 226503 by 19 
The aim is to understand the frequency of 19 in 226503.

On to step 1:
If we divide 2 by 19, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 19

Moving on to step 2:
The number 19 fits into 22 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 19 from 22, we get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 19

Advancing to step 3:
If we divide 36 by 19, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 11.0
If we take 19 away from 36, we end up with 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 19

Going ahead to step 4:
19 can be fit into 175 9 times, resulting in a remainder of 4.
The next digit of our result is 9. 
Result so far: 119.0
Deduct 171 from 175 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 19

Moving on to step 5:
40 divided by 19 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 1192.0
Subtract 38 from 40 to get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 19

On to step 6:
19 can be fit into 23 1 times, resulting in a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 11921.0
Subtract 19 from 23 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
19 can be fit into 40 2 times, resulting in a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 11921.2
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.

On to step 8:
20 divided by 19 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 11921.21
Subtract 19 from 20 to get 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 9:
19 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 11921.21
If we subtract 0 from 10, we get 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 10:
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: 11921.2105
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 11:
The number 19 fits into 50 2 times, leaving a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 11921.21052
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.

Going ahead to step 12:
When dividing 120 by 19, we get 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 11921.210526
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.

Moving on to step 13:
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: 11921.2105263
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.

Going ahead to step 14:
If we divide 30 by 19, we get 1 and a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 11921.21052631
Deduct 19 from 30 and we're left 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.

The quotient of the division is 11921.21052631, and the remainder is 1.1e-08.
