639312 ÷ 32 
Our goal is to divide 639312 by 32.

Moving on to step 1:
If we divide 6 by 32, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 32

Moving on to step 2:
63 divided by 32 is 1 with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 32 from 63 to get 31.
Include the next digit (9) from the dividend after 31, then repeat: 319 / 32

Moving on to step 3:
32 goes into 319 9 times with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 19.0
The remainder is 31 after subtracting 288 from 319.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 32

Moving on to step 4:
When dividing 313 by 32, we get 9 with a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 199.0
Subtracting 288 from 313 leaves us with 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 32

Let's proceed to step 5:
251 divided by 32 is 7 with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 1997.0
If we subtract 224 from 251, we get 27.
Bring next digit (2) of the dividend behind the 27 and repeat the process: 272 / 32

Step 6:
When dividing 272 by 32, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 19978.0
Deduct 256 from 272 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
When dividing 160 by 32, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 19978.5
Subtracting 160 from 160 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.

On to step 8:
The number 32 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 19978.5
If we take 0 away from 0, we end up 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.

On to step 9:
32 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 19978.5
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.

After the division, we end up with 19978.5 and a remainder of 0.0.
