We divide 536469 by 19
The aim is to understand the frequency of 19 in 536469.

Let's proceed to step 1:
19 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 19

Advancing to step 2:
19 goes into 53 2 times with a remainder of 15.
The next digit of our result is 2. 
Result so far: 2.0
If we take 38 away from 53, we end up with 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 19

On to step 3:
The number 19 fits into 156 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 152 from 156 and we're left with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 19

On to step 4:
The number 19 fits into 44 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 282.0
If we subtract 38 from 44, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 19

Moving on to step 5:
19 goes into 66 3 times with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 2823.0
Deduct 57 from 66 and we're left with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 19

Let's proceed to step 6:
99 divided by 19 is 5 with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 28235.0
Deduct 95 from 99 and we're left 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.

Moving on to step 7:
When dividing 40 by 19, we get 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 28235.2
Subtracting 38 from 40 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
The number 19 fits into 20 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 28235.21
If we subtract 19 from 20, we 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.

Going ahead to step 9:
If we divide 10 by 19, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 28235.21
Deduct 0 from 10 and we're left 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 10:
100 divided by 19 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 28235.2105
The remainder is 5 after subtracting 95 from 100.
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 11:
19 goes into 50 2 times with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 28235.21052
Subtracting 38 from 50 leaves us 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.

On to step 12:
19 can be fit into 120 6 times, resulting in a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 28235.210526
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.

Let's proceed to step 13:
The number 19 fits into 60 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 28235.2105263
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.

Step 14:
When dividing 30 by 19, we get 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 28235.21052631
Subtracting 19 from 30 leaves us 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.

After the division, we end up with 28235.21052631 and a remainder of 1.1e-08.
