We're dividing 639384 by 31 
Our goal is to divide 639384 by 31.

Moving on to step 1:
If we divide 6 by 31, we get 0 and 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.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 31

Advancing to step 2:
31 goes into 63 2 times with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 62 from 63 leaves us with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 31

Moving on to step 3:
The number 31 fits into 19 0 times, leaving a remainder of 19.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 19 to get 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 31

On to step 4:
31 can be fit into 193 6 times, resulting in a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 206.0
Subtracting 186 from 193 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 31

Going ahead to step 5:
78 divided by 31 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 2062.0
If we take 62 away from 78, we end up with 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 31

Let's proceed to step 6:
If we divide 164 by 31, we get 5 and a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 20625.0
If we take 155 away from 164, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
If we divide 90 by 31, we get 2 and a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 20625.2
If we take 62 away from 90, we end up 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.

Let's proceed to step 8:
If we divide 280 by 31, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 20625.29
If we subtract 279 from 280, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
The number 31 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 20625.29
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
100 divided by 31 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 20625.2903
If we take 93 away from 100, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 11:
31 can be fit into 70 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 20625.29032
The remainder is 8 after subtracting 62 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
If we divide 80 by 31, we get 2 and a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 20625.290322
If we subtract 62 from 80, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 20625.290322 and a remainder of 1.8e-06.
