We divide 780644 by 1
We want to figure out the number of times 780644 can be divided by 1.

Let's proceed 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
If we subtract 7 from 7, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Advancing to step 2:
1 goes into 8 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 78.0
If we subtract 8 from 8, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Advancing to step 3:
If we divide 0 by 1, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 780.0
The remainder is 0 after subtracting 0 from 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Let's proceed to step 4:
If we divide 6 by 1, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 7806.0
Subtracting 6 from 6 leaves us with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 1

Let's proceed to step 5:
The number 1 fits into 4 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 78064.0
Subtracting 4 from 4 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Moving on to step 6:
If we divide 4 by 1, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 780644.0
If we take 4 away from 4, 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.

Moving on to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 780644.0
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.

Advancing to step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 780644.0
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 result is 780644.0 with a remainder of 0.0.
