596512 ÷ 19 
The aim is to understand the frequency of 19 in 596512.

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
Deduct 0 from 5 and we're left with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 19

Let's proceed to step 2:
If we divide 59 by 19, we get 3 and a remainder of 2.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 57 from 59 and we're left with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 19

On to step 3:
If we divide 26 by 19, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtracting 19 from 26 leaves us with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 19

Going ahead 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: 313.0
Deduct 57 from 75 and we're left with 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 19

Step 5:
19 goes into 181 9 times with a remainder of 10.
The next digit of our result is 9. 
Result so far: 3139.0
Deduct 171 from 181 and we're left with 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 19

Moving on to step 6:
When dividing 102 by 19, we get 5 with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 31395.0
If we take 95 away from 102, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
70 divided by 19 is 3 with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 31395.3
The remainder is 13 after subtracting 57 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 8:
19 goes into 130 6 times with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 31395.36
Subtracting 114 from 130 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
When dividing 160 by 19, we get 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 31395.368
The remainder is 8 after subtracting 152 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
If we divide 80 by 19, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 31395.3684
Subtract 76 from 80 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.

Let's proceed to step 11:
The number 19 fits into 40 2 times, leaving a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 31395.36842
If we take 38 away from 40, we end up 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.

Advancing to step 12:
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: 31395.368421
Subtracting 19 from 20 leaves us 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.

Step 13:
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: 31395.368421
Subtract 0 from 10 to 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 14:
19 can be fit into 100 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 31395.36842105
If we take 95 away from 100, we end up 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.

The quotient of the division is 31395.36842105, and the remainder is 5e-09.
