We look at the division of 640217 by 19 
We want to figure out the number of times 640217 can be divided by 19.

On to step 1:
The number 19 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 19

Step 2:
19 can be fit into 64 3 times, resulting in a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 57 away from 64, we end up with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 19

On to step 3:
If we divide 70 by 19, we get 3 and a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Subtract 57 from 70 to get 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 19

Step 4:
The number 19 fits into 132 6 times, leaving a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 336.0
The remainder is 18 after subtracting 114 from 132.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 19

Going ahead to step 5:
19 goes into 181 9 times with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 3369.0
Subtracting 171 from 181 leaves us with 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 19

Step 6:
19 can be fit into 107 5 times, resulting in a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 33695.0
The remainder is 12 after subtracting 95 from 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
If we divide 120 by 19, we get 6 and a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 33695.6
If we take 114 away from 120, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
When dividing 60 by 19, we get 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 33695.63
The remainder is 3 after subtracting 57 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
The number 19 fits into 30 1 times, leaving a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 33695.631
The remainder is 11 after subtracting 19 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 10:
110 divided by 19 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 33695.6315
If we subtract 95 from 110, we 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.

Advancing to step 11:
150 divided by 19 is 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 33695.63157
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.

Going ahead to step 12:
170 divided by 19 is 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 33695.631578
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.

Let's proceed to step 13:
The number 19 fits into 180 9 times, leaving a remainder of 9.
The next digit of our result is 9. 
Result so far: 33695.6315789
The remainder is 9 after subtracting 171 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 14:
When dividing 90 by 19, we get 4 with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 33695.63157894
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.

After the division, we end up with 33695.63157894 and a remainder of 1.4e-08.
