678381 divided by 80 
We want to figure out the number of times 678381 can be divided by 80.

Advancing to step 1:
80 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 80

Advancing to step 2:
When dividing 67 by 80, we get 0 with a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 67 leaves us with 67.
Fetch the next digit (8) from the dividend, attach it to 67 and continue: 678 / 80

Advancing to step 3:
80 can be fit into 678 8 times, resulting in a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 640 from 678 leaves us with 38.
Fetch the next digit (3) from the dividend, attach it to 38 and continue: 383 / 80

Step 4:
When dividing 383 by 80, we get 4 with a remainder of 63.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
Deduct 320 from 383 and we're left with 63.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 80

Step 5:
80 goes into 638 7 times with a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 847.0
Deduct 560 from 638 and we're left with 78.
Take the next digit (1) from the dividend and append it to 78, then repeat: 781 / 80

On to step 6:
80 goes into 781 9 times with a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 8479.0
If we subtract 720 from 781, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 7:
80 can be fit into 610 7 times, resulting in a remainder of 50.
The next digit of our result is 7. 
Result so far: 8479.7
If we take 560 away from 610, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
When dividing 500 by 80, we get 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 8479.76
If we take 480 away from 500, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
The number 80 fits into 200 2 times, leaving a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 8479.762
If we take 160 away from 200, 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.

Going ahead to step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 8479.7625
The remainder is 0 after subtracting 400 from 400.
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 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8479.7625
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.

On to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8479.7625
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.

The final result is 8479.7625 with a remainder of 0.0.
