We're dividing 572697 by 19 
The aim is to understand the frequency of 19 in 572697.

Advancing to step 1:
If we divide 5 by 19, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 19

On to step 2:
The number 19 fits into 57 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
If we take 57 away from 57, we end up with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 19

Let's proceed to step 3:
When dividing 2 by 19, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 30.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 19

Going ahead to step 4:
When dividing 26 by 19, we get 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 301.0
If we take 19 away from 26, we end up with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 19

Let's proceed to step 5:
The number 19 fits into 79 4 times, leaving a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 3014.0
Deduct 76 from 79 and we're left with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 19

Moving on to step 6:
When dividing 37 by 19, we get 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 30141.0
The remainder is 18 after subtracting 19 from 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
180 divided by 19 is 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 30141.9
Deduct 171 from 180 and we're left with 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 8:
19 goes into 90 4 times with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 30141.94
Subtracting 76 from 90 leaves us 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 9:
If we divide 140 by 19, we get 7 and a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 30141.947
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 10:
70 divided by 19 is 3 with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 30141.9473
If we take 57 away from 70, we end up 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.

Going ahead to step 11:
130 divided by 19 is 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 30141.94736
Deduct 114 from 130 and we're left 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.

Advancing to step 12:
The number 19 fits into 160 8 times, leaving a remainder of 8.
The next digit of our result is 8. 
Result so far: 30141.947368
Subtracting 152 from 160 leaves us 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.

Advancing to step 13:
80 divided by 19 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 30141.9473684
Subtracting 76 from 80 leaves us 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.

On to step 14:
40 divided by 19 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 30141.94736842
Deduct 38 from 40 and we're left 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.

Our division results in 30141.94736842 with a remaining 2e-09.
