We look at the division of 630819 by 20 
Let's see how many times 20 fits into 630819.

Going ahead to step 1:
If we divide 6 by 20, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 20

Step 2:
When dividing 63 by 20, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 3 after subtracting 60 from 63.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 20

Moving on to step 3:
30 divided by 20 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 31.0
The remainder is 10 after subtracting 20 from 30.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 20

Moving on to step 4:
108 divided by 20 is 5 with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 315.0
Deduct 100 from 108 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 20

Moving on to step 5:
The number 20 fits into 81 4 times, leaving a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 3154.0
Deduct 80 from 81 and we're left with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 20

Going ahead to step 6:
If we divide 19 by 20, we get 0 and a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 31540.0
Subtracting 0 from 19 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
20 can be fit into 190 9 times, resulting in a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 31540.9
Deduct 180 from 190 and we're left 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.

Let's proceed to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 31540.95
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.

Step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 31540.95
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.

Moving on to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 31540.95
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.

In conclusion, the division gives 31540.95 with a balance of 0.0.
