Let's divide 640811 by 35
We want to divide 640811 by 35.

Step 1:
If we divide 6 by 35, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 35

Advancing to step 2:
If we divide 64 by 35, we get 1 and a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 35 from 64 to get 29.
Append the next digit (0) from the dividend to 29 and continue with: 290 / 35

Moving on to step 3:
If we divide 290 by 35, we get 8 and a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 10 after subtracting 280 from 290.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 35

On to step 4:
The number 35 fits into 108 3 times, leaving a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 183.0
Subtracting 105 from 108 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 35

Advancing to step 5:
31 divided by 35 is 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 1830.0
If we take 0 away from 31, we end up with 31.
Fetch the next digit (1) from the dividend, attach it to 31 and continue: 311 / 35

Advancing to step 6:
If we divide 311 by 35, we get 8 and a remainder of 31.
The number 8 becomes the next digit in our result. 
Result so far: 18308.0
Subtracting 280 from 311 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
The number 35 fits into 310 8 times, leaving a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 18308.8
The remainder is 30 after subtracting 280 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
300 divided by 35 is 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 18308.88
Subtract 280 from 300 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.

The quotient of the division is 18308.88, and the remainder is 0.02.
