648780 ÷ 1 
Our goal is to divide 648780 by 1.

Let's proceed to step 1:
1 can be fit into 6 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 6 away from 6, we end up with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 1

Going ahead to step 2:
When dividing 4 by 1, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
The remainder is 0 after subtracting 4 from 4.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Let's proceed to step 3:
1 goes into 8 8 times with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 648.0
Deduct 8 from 8 and we're left with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 1

On to step 4:
1 goes into 7 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 6487.0
Deduct 7 from 7 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

Going ahead to step 5:
When dividing 8 by 1, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 64878.0
If we subtract 8 from 8, we get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

On to step 6:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 648780.0
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.

Advancing to step 7:
1 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 648780.0
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.

Advancing to step 8:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 648780.0
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.

In conclusion, the division gives 648780.0 with a balance of 0.0.
