478387 divided by 80 
We're looking to find how many times 80 goes into 478387.

Let's proceed to step 1:
When dividing 4 by 80, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 80

Advancing to step 2:
80 goes into 47 0 times with a remainder of 47.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 47 leaves us with 47.
Bring next digit (8) of the dividend behind the 47 and repeat the process: 478 / 80

Step 3:
478 divided by 80 is 5 with a remainder of 78.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 400 away from 478, we end up with 78.
Append the next digit (3) from the dividend to 78 and continue with: 783 / 80

Let's proceed to step 4:
When dividing 783 by 80, we get 9 with a remainder of 63.
The next digit of our result is 9. 
Result so far: 59.0
The remainder is 63 after subtracting 720 from 783.
Fetch the next digit (8) from the dividend, attach it to 63 and continue: 638 / 80

Step 5:
80 goes into 638 7 times with a remainder of 78.
Use 7 as the next digit of our solution. 
Result so far: 597.0
Subtract 560 from 638 to get 78.
Bring next digit (7) of the dividend behind the 78 and repeat the process: 787 / 80

Moving on to step 6:
When dividing 787 by 80, we get 9 with a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 5979.0
If we take 720 away from 787, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 7:
The number 80 fits into 670 8 times, leaving a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 5979.8
The remainder is 30 after subtracting 640 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
300 divided by 80 is 3 with a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 5979.83
Subtract 240 from 300 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
When dividing 600 by 80, we get 7 with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 5979.837
If we take 560 away from 600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
80 goes into 400 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5979.8375
If we take 400 away from 400, 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 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 5979.8375
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5979.8375
The remainder is 0 after subtracting 0 from 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 5979.8375, with a leftover of 0.0.
