We look at the division of 639695 by 20 
We want to divide 639695 by 20.

Let's proceed to step 1:
6 divided by 20 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 20

Let's proceed to step 2:
20 goes into 63 3 times with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 3 after subtracting 60 from 63.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 20

On to step 3:
If we divide 39 by 20, we get 1 and a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 31.0
If we subtract 20 from 39, we get 19.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 20

Step 4:
If we divide 196 by 20, we get 9 and a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 319.0
Subtract 180 from 196 to get 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 20

On to step 5:
When dividing 169 by 20, we get 8 with a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 3198.0
Subtract 160 from 169 to get 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 20

Step 6:
If we divide 95 by 20, we get 4 and a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 31984.0
Deduct 80 from 95 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
When dividing 150 by 20, we get 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 31984.7
The remainder is 10 after subtracting 140 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 20 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 31984.75
Deduct 100 from 100 and we're left 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.

Moving on to step 9:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 31984.75
Deduct 0 from 0 and we're left 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.

Let's proceed to step 10:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 31984.75
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.

In conclusion, the division gives 31984.75 with a balance of 0.0.
