We look at the division of 41420378 by 80 
We want to divide 41420378 by 80.

Step 1:
4 divided by 80 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 80

Advancing to step 2:
When dividing 41 by 80, we get 0 with a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 41 leaves us with 41.
Bring next digit (4) of the dividend behind the 41 and repeat the process: 414 / 80

Let's proceed to step 3:
If we divide 414 by 80, we get 5 and a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 400 from 414 leaves us with 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 80

Advancing to step 4:
The number 80 fits into 142 1 times, leaving a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
If we subtract 80 from 142, we get 62.
Grab the next digit (0) from the dividend, add it to 62, then carry on: 620 / 80

Going ahead to step 5:
The number 80 fits into 620 7 times, leaving a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 517.0
Deduct 560 from 620 and we're left with 60.
Take the next digit (3) from the dividend and append it to 60, then repeat: 603 / 80

Step 6:
When dividing 603 by 80, we get 7 with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 5177.0
If we take 560 away from 603, we end up with 43.
Fetch the next digit (7) from the dividend, attach it to 43 and continue: 437 / 80

Let's proceed to step 7:
80 goes into 437 5 times with a remainder of 37.
The number 5 becomes the next digit in our result. 
Result so far: 51775.0
Subtract 400 from 437 to get 37.
Fetch the next digit (8) from the dividend, attach it to 37 and continue: 378 / 80

On to step 8:
80 can be fit into 378 4 times, resulting in a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 517754.0
Subtract 320 from 378 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 9:
The number 80 fits into 580 7 times, leaving a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 517754.7
Deduct 560 from 580 and we're left 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.

On to step 10:
If we divide 200 by 80, we get 2 and a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 517754.72
Subtract 160 from 200 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 517754.725
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.

Advancing to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 517754.725
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.

On to step 13:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 517754.725
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.

In conclusion, the division gives 517754.725 with a balance of 0.0.
