627643 divided by 20 
Our goal is to divide 627643 by 20.

Step 1:
If we divide 6 by 20, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 20

Let's proceed to step 2:
The number 20 fits into 62 3 times, leaving a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 60 from 62 leaves us with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 20

Let's proceed to step 3:
20 goes into 27 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 31.0
The remainder is 7 after subtracting 20 from 27.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 20

Step 4:
20 can be fit into 76 3 times, resulting in a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 313.0
Deduct 60 from 76 and we're left with 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 20

Let's proceed to step 5:
If we divide 164 by 20, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 3138.0
Deduct 160 from 164 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 20

Step 6:
The number 20 fits into 43 2 times, leaving a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 31382.0
If we subtract 40 from 43, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
20 goes into 30 1 times with a remainder of 10.
The next digit of our result is 1. 
Result so far: 31382.1
If we take 20 away from 30, 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.

On to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 31382.15
If we subtract 100 from 100, 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.

Advancing to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 31382.15
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.

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: 31382.15
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.

In conclusion, the division gives 31382.15 with a balance of 0.0.
