628854 ÷ 20 
We want to figure out the number of times 628854 can be divided by 20.

On to 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
Subtracting 0 from 6 leaves us with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 20

Advancing to step 2:
20 can be fit into 62 3 times, resulting in a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 60 from 62 leaves us with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 20

On to step 3:
20 goes into 28 1 times with a remainder of 8.
The next digit of our result is 1. 
Result so far: 31.0
Subtract 20 from 28 to get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 20

Going ahead to step 4:
When dividing 88 by 20, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 314.0
If we take 80 away from 88, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 20

Step 5:
20 goes into 85 4 times with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 3144.0
The remainder is 5 after subtracting 80 from 85.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 20

Going ahead to step 6:
When dividing 54 by 20, we get 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 31442.0
If we subtract 40 from 54, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
140 divided by 20 is 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 31442.7
Subtract 140 from 140 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.

Step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 31442.7
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.

Step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 31442.7
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.

The final result is 31442.7 with a remainder of 0.0.
