458017 ÷ 80 
Let's see how many times 80 fits into 458017.

Advancing to step 1:
The number 80 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 80

Going ahead to step 2:
45 divided by 80 is 0 with a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Append the next digit (8) from the dividend to 45 and continue with: 458 / 80

Moving on to step 3:
The number 80 fits into 458 5 times, leaving a remainder of 58.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 400 from 458 leaves us with 58.
Include the next digit (0) from the dividend after 58, then repeat: 580 / 80

Step 4:
80 goes into 580 7 times with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 57.0
If we take 560 away from 580, we end up with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 80

Moving on to step 5:
When dividing 201 by 80, we get 2 with a remainder of 41.
The next digit of our result is 2. 
Result so far: 572.0
The remainder is 41 after subtracting 160 from 201.
Append the next digit (7) from the dividend to 41 and continue with: 417 / 80

Going ahead to step 6:
417 divided by 80 is 5 with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 5725.0
Deduct 400 from 417 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
If we divide 170 by 80, we get 2 and a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 5725.2
The remainder is 10 after subtracting 160 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
The number 80 fits into 100 1 times, leaving a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 5725.21
If we take 80 away from 100, 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.

Advancing to step 9:
When dividing 200 by 80, we get 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 5725.212
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 10:
400 divided by 80 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5725.2125
If we subtract 400 from 400, 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.

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: 5725.2125
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.

Step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 5725.2125
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.

The final outcome is 5725.2125, with a leftover of 0.0.
