We're dividing 770584 by 1 
Our goal is to divide 770584 by 1.

Moving on to step 1:
The number 1 fits into 7 7 times, leaving a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 7 from 7 and we're left with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 1

Advancing to step 2:
When dividing 7 by 1, we get 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 77.0
If we take 7 away from 7, we end up with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Step 3:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 770.0
If we take 0 away from 0, we end up with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Step 4:
1 goes into 5 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 7705.0
Subtracting 5 from 5 leaves us with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

Advancing to step 5:
1 can be fit into 8 8 times, resulting in a remainder of 0.
The next digit of our result is 8. 
Result so far: 77058.0
Subtract 8 from 8 to get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Let's proceed to step 6:
1 goes into 4 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 770584.0
The remainder is 0 after subtracting 4 from 4.
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 7:
1 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 770584.0
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.

Let's proceed to step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 770584.0
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.

The final outcome is 770584.0, with a leftover of 0.0.
