We're dividing 505958 by 19 
The aim is to understand the frequency of 19 in 505958.

Advancing to step 1:
19 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 19

On to step 2:
When dividing 50 by 19, we get 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 38 away from 50, we end up with 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 19

On to step 3:
19 goes into 125 6 times with a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 26.0
The remainder is 11 after subtracting 114 from 125.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 19

Let's proceed to step 4:
19 can be fit into 119 6 times, resulting in a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 266.0
Deduct 114 from 119 and we're left with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 19

Let's proceed to step 5:
19 goes into 55 2 times with a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 2662.0
Deduct 38 from 55 and we're left with 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 19

Going ahead to step 6:
The number 19 fits into 178 9 times, leaving a remainder of 7.
The next digit of our result is 9. 
Result so far: 26629.0
If we subtract 171 from 178, 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.

Moving on to step 7:
19 can be fit into 70 3 times, resulting in a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 26629.3
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.

Let's proceed 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: 26629.36
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.

Moving on to step 9:
19 can be fit into 160 8 times, resulting in a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 26629.368
Subtract 152 from 160 to get 8.
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:
19 goes into 80 4 times with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 26629.3684
Deduct 76 from 80 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 11:
19 goes into 40 2 times with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 26629.36842
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 12:
20 divided by 19 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 26629.368421
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.

Moving on to step 13:
10 divided by 19 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 26629.368421
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.

Advancing to step 14:
When dividing 100 by 19, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 26629.36842105
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.

The final result is 26629.36842105 with a remainder of 5e-09.
