We divide 406378 by 80
We want to divide 406378 by 80.

On to step 1:
When dividing 4 by 80, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 80

Step 2:
80 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Append the next digit (6) from the dividend to 40 and continue with: 406 / 80

Going ahead to step 3:
When dividing 406 by 80, we get 5 with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 400 away from 406, we end up with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 80

Advancing to step 4:
If we divide 63 by 80, we get 0 and a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
If we take 0 away from 63, we end up with 63.
Take the next digit (7) from the dividend and append it to 63, then repeat: 637 / 80

Let's proceed to step 5:
If we divide 637 by 80, we get 7 and a remainder of 77.
The number 7 becomes the next digit in our result. 
Result so far: 507.0
If we subtract 560 from 637, we get 77.
Fetch the next digit (8) from the dividend, attach it to 77 and continue: 778 / 80

Moving on to step 6:
80 can be fit into 778 9 times, resulting in a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 5079.0
Subtracting 720 from 778 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 7:
580 divided by 80 is 7 with a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 5079.7
The remainder is 20 after subtracting 560 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
If we divide 200 by 80, we get 2 and a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 5079.72
Deduct 160 from 200 and we're left 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.

On to step 9:
When dividing 400 by 80, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5079.725
Subtracting 400 from 400 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 10:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5079.725
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 11:
0 divided by 80 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5079.725
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.

After the division, we end up with 5079.725 and a remainder of 0.0.
