We look at the division of 629863 by 20 
Our goal is to divide 629863 by 20.

Step 1:
20 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 20

Advancing to step 2:
The number 20 fits into 62 3 times, leaving a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 60 from 62 to get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 20

Moving on to step 3:
If we divide 29 by 20, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
If we take 20 away from 29, we end up with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 20

Going ahead to step 4:
The number 20 fits into 98 4 times, leaving a remainder of 18.
The next digit of our result is 4. 
Result so far: 314.0
Subtract 80 from 98 to get 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 20

Moving on to step 5:
20 can be fit into 186 9 times, resulting in a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 3149.0
Deduct 180 from 186 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 20

Advancing to step 6:
When dividing 63 by 20, we get 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 31493.0
Deduct 60 from 63 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
20 can be fit into 30 1 times, resulting in a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 31493.1
If we subtract 20 from 30, we get 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 8:
100 divided by 20 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 31493.15
Subtract 100 from 100 to 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.

Moving on to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 31493.15
Subtract 0 from 0 to 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.

Let's proceed to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 31493.15
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.

The final outcome is 31493.15, with a leftover of 0.0.
