630679 ÷ 20 
We want to divide 630679 by 20.

Going ahead to step 1:
20 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 20

On to 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
Subtract 60 from 63 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 20

Step 3:
When dividing 30 by 20, we get 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we subtract 20 from 30, we get 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 20

Let's proceed to step 4:
106 divided by 20 is 5 with a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 315.0
If we take 100 away from 106, we end up with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 20

On to step 5:
The number 20 fits into 67 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 3153.0
Subtract 60 from 67 to get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 20

On to step 6:
The number 20 fits into 79 3 times, leaving a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 31533.0
If we subtract 60 from 79, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
The number 20 fits into 190 9 times, leaving a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 31533.9
The remainder is 10 after subtracting 180 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
100 divided by 20 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 31533.95
The remainder is 0 after subtracting 100 from 100.
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:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 31533.95
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.

Step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 31533.95
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.

In conclusion, the division gives 31533.95 with a balance of 0.0.
