517672 divided by 19 
The aim is to understand the frequency of 19 in 517672.

Let's proceed to step 1:
19 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 19

Let's proceed to step 2:
When dividing 51 by 19, we get 2 with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 38 from 51, we get 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 19

Advancing to step 3:
If we divide 137 by 19, we get 7 and a remainder of 4.
The next digit of our result is 7. 
Result so far: 27.0
Subtract 133 from 137 to get 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 19

Going ahead to step 4:
If we divide 46 by 19, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 272.0
Subtracting 38 from 46 leaves us with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 19

Going ahead to step 5:
The number 19 fits into 87 4 times, leaving a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 2724.0
If we take 76 away from 87, we end up with 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 19

On to step 6:
The number 19 fits into 112 5 times, leaving a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 27245.0
The remainder is 17 after subtracting 95 from 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
170 divided by 19 is 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 27245.8
Subtract 152 from 170 to 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.

Going ahead to step 8:
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: 27245.89
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.

Moving on to step 9:
90 divided by 19 is 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 27245.894
If we subtract 76 from 90, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
19 can be fit into 140 7 times, resulting in a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 27245.8947
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.

Let's proceed to step 11:
The number 19 fits into 70 3 times, leaving a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 27245.89473
Deduct 57 from 70 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 12:
19 goes into 130 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 27245.894736
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.

Moving on to step 13:
When dividing 160 by 19, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 27245.8947368
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.

Going ahead to step 14:
80 divided by 19 is 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 27245.89473684
If we subtract 76 from 80, we 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.

After the division, we end up with 27245.89473684 and a remainder of 4e-09.
