We're dividing 590459 by 19 
The aim is to understand the frequency of 19 in 590459.

Let's proceed to step 1:
19 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 19

On to step 2:
19 goes into 59 3 times with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 57 away from 59, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 19

Let's proceed to step 3:
When dividing 20 by 19, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 31.0
The remainder is 1 after subtracting 19 from 20.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 19

Advancing to step 4:
14 divided by 19 is 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 310.0
If we take 0 away from 14, we end up with 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 19

Step 5:
145 divided by 19 is 7 with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 3107.0
Subtracting 133 from 145 leaves us with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 19

Moving on to step 6:
The number 19 fits into 129 6 times, leaving a remainder of 15.
The next digit of our result is 6. 
Result so far: 31076.0
Subtracting 114 from 129 leaves us 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.

Let's proceed to step 7:
When dividing 150 by 19, we get 7 with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 31076.7
If we take 133 away from 150, we end up 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.

Moving on to step 8:
If we divide 170 by 19, we get 8 and a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 31076.78
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.

Step 9:
The number 19 fits into 180 9 times, leaving a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 31076.789
Subtract 171 from 180 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
90 divided by 19 is 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 31076.7894
If we take 76 away from 90, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 11:
140 divided by 19 is 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 31076.78947
If we subtract 133 from 140, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 12:
70 divided by 19 is 3 with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 31076.789473
If we subtract 57 from 70, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 13:
19 can be fit into 130 6 times, resulting in a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 31076.7894736
The remainder is 16 after subtracting 114 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
When dividing 160 by 19, we get 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 31076.78947368
Deduct 152 from 160 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 31076.78947368, with a leftover of 8e-09.
