Let's divide 640873 by 34
We want to figure out the number of times 640873 can be divided by 34.

Going ahead to step 1:
6 divided by 34 is 0 with 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.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 34

Moving on to step 2:
The number 34 fits into 64 1 times, leaving a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 30 after subtracting 34 from 64.
Fetch the next digit (0) from the dividend, attach it to 30 and continue: 300 / 34

Moving on to step 3:
300 divided by 34 is 8 with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 18.0
The remainder is 28 after subtracting 272 from 300.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 34

Let's proceed to step 4:
34 goes into 288 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 188.0
Subtracting 272 from 288 leaves us with 16.
Bring next digit (7) of the dividend behind the 16 and repeat the process: 167 / 34

Moving on to step 5:
The number 34 fits into 167 4 times, leaving a remainder of 31.
Use 4 as the next digit of our solution. 
Result so far: 1884.0
Subtracting 136 from 167 leaves us with 31.
Bring next digit (3) of the dividend behind the 31 and repeat the process: 313 / 34

Going ahead to step 6:
313 divided by 34 is 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 18849.0
Subtracting 306 from 313 leaves us with 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:
If we divide 70 by 34, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 18849.2
Deduct 68 from 70 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.

Step 8:
34 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 18849.2
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
If we divide 200 by 34, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 18849.205
The remainder is 30 after subtracting 170 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
300 divided by 34 is 8 with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 18849.2058
Subtracting 272 from 300 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
34 can be fit into 280 8 times, resulting in a remainder of 8.
The next digit of our result is 8. 
Result so far: 18849.20588
The remainder is 8 after subtracting 272 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 18849.20588, with a leftover of 8e-06.
