We're dividing 639802 by 1 
Let's see how many times 1 fits into 639802.

On to step 1:
The number 1 fits into 6 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 6 from 6 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

Let's proceed to step 2:
1 can be fit into 3 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 63.0
The remainder is 0 after subtracting 3 from 3.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

Let's proceed to step 3:
If we divide 9 by 1, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 639.0
Deduct 9 from 9 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

Let's proceed to step 4:
The number 1 fits into 8 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 6398.0
Subtract 8 from 8 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Step 5:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 63980.0
If we take 0 away from 0, we end up with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

Moving on to step 6:
If we divide 2 by 1, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 639802.0
The remainder is 0 after subtracting 2 from 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 639802.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 639802.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 639802.0, and the remainder is 0.0.
