We're dividing 454818 by 80 
We want to figure out the number of times 454818 can be divided by 80.

Let's proceed to step 1:
4 divided by 80 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 80

Advancing to step 2:
If we divide 45 by 80, we get 0 and a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Append the next digit (4) from the dividend to 45 and continue with: 454 / 80

Advancing to step 3:
The number 80 fits into 454 5 times, leaving a remainder of 54.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 400 from 454 to get 54.
Grab the next digit (8) from the dividend, add it to 54, then carry on: 548 / 80

Step 4:
80 goes into 548 6 times with a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 56.0
Subtract 480 from 548 to get 68.
Grab the next digit (1) from the dividend, add it to 68, then carry on: 681 / 80

Let's proceed to step 5:
80 goes into 681 8 times with a remainder of 41.
Record the quotient 8 as the next digit in the result. 
Result so far: 568.0
Deduct 640 from 681 and we're left with 41.
Take the next digit (8) from the dividend and append it to 41, then repeat: 418 / 80

Moving on to step 6:
418 divided by 80 is 5 with a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 5685.0
If we subtract 400 from 418, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
80 can be fit into 180 2 times, resulting in a remainder of 20.
The next digit of our result is 2. 
Result so far: 5685.2
The remainder is 20 after subtracting 160 from 180.
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 8:
If we divide 200 by 80, we get 2 and a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 5685.22
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.

The final outcome is 5685.22, with a leftover of 0.04.
