639516 divided by 10 
Let's see how many times 10 fits into 639516.

On to step 1:
6 divided by 10 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 10

On to step 2:
10 can be fit into 63 6 times, resulting in a remainder of 3.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 60 from 63 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 10

Step 3:
39 divided by 10 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
The remainder is 9 after subtracting 30 from 39.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 10

Let's proceed to step 4:
The number 10 fits into 95 9 times, leaving a remainder of 5.
The next digit of our result is 9. 
Result so far: 639.0
Deduct 90 from 95 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 10

Let's proceed to step 5:
10 can be fit into 51 5 times, resulting in a remainder of 1.
The next digit of our result is 5. 
Result so far: 6395.0
The remainder is 1 after subtracting 50 from 51.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 10

Moving on to step 6:
10 can be fit into 16 1 times, resulting in a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 63951.0
Subtract 10 from 16 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
The number 10 fits into 60 6 times, leaving a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 63951.6
Subtracting 60 from 60 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.

Step 8:
If we divide 0 by 10, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 63951.6
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
When dividing 0 by 10, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 63951.6
If we subtract 0 from 0, we get 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 63951.6, and the remainder is 0.0.
