We're dividing 664897 by 19 
The aim is to understand the frequency of 19 in 664897.

Let's proceed to step 1:
If we divide 6 by 19, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 19

Moving on to step 2:
19 goes into 66 3 times with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 9 after subtracting 57 from 66.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 19

On to step 3:
When dividing 94 by 19, we get 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Subtracting 76 from 94 leaves us with 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 19

On to step 4:
188 divided by 19 is 9 with a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 349.0
If we subtract 171 from 188, we get 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 19

Advancing to step 5:
If we divide 179 by 19, we get 9 and a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 3499.0
Subtract 171 from 179 to get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 19

Advancing to step 6:
If we divide 87 by 19, we get 4 and a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 34994.0
If we subtract 76 from 87, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
When dividing 110 by 19, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 34994.5
Subtract 95 from 110 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
When dividing 150 by 19, we get 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 34994.57
If we subtract 133 from 150, we get 17.
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 9:
170 divided by 19 is 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 34994.578
The remainder is 18 after subtracting 152 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
If we divide 180 by 19, we get 9 and a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 34994.5789
If we take 171 away from 180, we end up 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.

Step 11:
If we divide 90 by 19, we get 4 and a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 34994.57894
Deduct 76 from 90 and we're left 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.

Moving on to step 12:
140 divided by 19 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 34994.578947
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.

Step 13:
19 goes into 70 3 times with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 34994.5789473
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.

Let's proceed to step 14:
The number 19 fits into 130 6 times, leaving a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 34994.57894736
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.

Our division results in 34994.57894736 with a remaining 1.6e-08.
