Let's divide 639560 by 34
We're looking to find how many times 34 goes into 639560.

Going ahead to step 1:
34 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 34

Going ahead to step 2:
34 goes into 63 1 times with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 34 from 63 to get 29.
Fetch the next digit (9) from the dividend, attach it to 29 and continue: 299 / 34

Advancing to step 3:
299 divided by 34 is 8 with a remainder of 27.
Write down 8 as next digit of the result. 
Result so far: 18.0
The remainder is 27 after subtracting 272 from 299.
Grab the next digit (5) from the dividend, add it to 27, then carry on: 275 / 34

Advancing to step 4:
275 divided by 34 is 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 188.0
Deduct 272 from 275 and we're left with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 34

Let's proceed to step 5:
The number 34 fits into 36 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1881.0
Deduct 34 from 36 and we're left with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 34

On to step 6:
20 divided by 34 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 18810.0
Subtract 0 from 20 to 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.

Moving on to step 7:
The number 34 fits into 200 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 18810.5
Subtract 170 from 200 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
If we divide 300 by 34, we get 8 and a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 18810.58
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.

Moving on to step 9:
When dividing 280 by 34, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 18810.588
Subtracting 272 from 280 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.

The final outcome is 18810.588, with a leftover of 0.0008.
