We divide 408719 by 80
We want to figure out the number of times 408719 can be divided by 80.

Step 1:
The number 80 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 80

Moving on to step 2:
If we divide 40 by 80, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Bring next digit (8) of the dividend behind the 40 and repeat the process: 408 / 80

Step 3:
80 goes into 408 5 times with a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 400 away from 408, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 80

Going ahead to step 4:
80 can be fit into 87 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
Subtract 80 from 87 to get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 80

Going ahead to step 5:
The number 80 fits into 71 0 times, leaving a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 510.0
Subtract 0 from 71 to get 71.
Include the next digit (9) from the dividend after 71, then repeat: 719 / 80

Step 6:
719 divided by 80 is 8 with a remainder of 79.
Use 8 as the next digit of our solution. 
Result so far: 5108.0
If we take 640 away from 719, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 7:
790 divided by 80 is 9 with a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 5108.9
If we take 720 away from 790, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
If we divide 700 by 80, we get 8 and a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 5108.98
The remainder is 60 after subtracting 640 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
The number 80 fits into 600 7 times, leaving a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 5108.987
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5108.9875
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:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5108.9875
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.

Step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5108.9875
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 5108.9875, with a leftover of 0.0.
