We're dividing 715480 by 1 
We're looking to find how many times 1 goes into 715480.

Let's proceed to step 1:
The number 1 fits into 7 7 times, leaving a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 7 from 7 to get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

On to step 2:
1 divided by 1 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 71.0
If we take 1 away from 1, we end up with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Moving on to step 3:
The number 1 fits into 5 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 715.0
The remainder is 0 after subtracting 5 from 5.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Advancing to step 4:
1 goes into 4 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 7154.0
Subtracting 4 from 4 leaves us with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

Moving on to step 5:
1 goes into 8 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 71548.0
If we subtract 8 from 8, we get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

Moving on to step 6:
When dividing 0 by 1, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 715480.0
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.

On to step 7:
0 divided by 1 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 715480.0
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.

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: 715480.0
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.

The final outcome is 715480.0, with a leftover of 0.0.
