419991 divided by 80 
Let's see how many times 80 fits into 419991.

Going ahead to step 1:
80 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 80

Moving on to step 2:
80 can be fit into 41 0 times, resulting in a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 41 leaves us with 41.
Append the next digit (9) from the dividend to 41 and continue with: 419 / 80

Let's proceed to step 3:
80 goes into 419 5 times with a remainder of 19.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 19 after subtracting 400 from 419.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 80

Going ahead to step 4:
80 can be fit into 199 2 times, resulting in a remainder of 39.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Deduct 160 from 199 and we're left with 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 80

Moving on to step 5:
399 divided by 80 is 4 with a remainder of 79.
Put 4 as the next digit of the answer. 
Result so far: 524.0
If we take 320 away from 399, we end up with 79.
Include the next digit (1) from the dividend after 79, then repeat: 791 / 80

Going ahead to step 6:
791 divided by 80 is 9 with a remainder of 71.
The number 9 becomes the next digit in our result. 
Result so far: 5249.0
Deduct 720 from 791 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 7:
When dividing 710 by 80, we get 8 with a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 5249.8
Subtract 640 from 710 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
The number 80 fits into 700 8 times, leaving a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 5249.88
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.

In conclusion, the division gives 5249.88 with a balance of 0.06.
