452144 ÷ 80 
We want to figure out the number of times 452144 can be divided by 80.

Going ahead to step 1:
The number 80 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 80

Advancing to step 2:
The number 80 fits into 45 0 times, leaving a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Include the next digit (2) from the dividend after 45, then repeat: 452 / 80

On to step 3:
If we divide 452 by 80, we get 5 and a remainder of 52.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 400 from 452 and we're left with 52.
Fetch the next digit (1) from the dividend, attach it to 52 and continue: 521 / 80

Let's proceed to step 4:
If we divide 521 by 80, we get 6 and a remainder of 41.
The next digit of our result is 6. 
Result so far: 56.0
If we subtract 480 from 521, we get 41.
Append the next digit (4) from the dividend to 41 and continue with: 414 / 80

Step 5:
80 can be fit into 414 5 times, resulting in a remainder of 14.
The next digit of our result is 5. 
Result so far: 565.0
If we subtract 400 from 414, we get 14.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 80

Going ahead to step 6:
144 divided by 80 is 1 with a remainder of 64.
The number 1 becomes the next digit in our result. 
Result so far: 5651.0
Subtract 80 from 144 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 7:
80 can be fit into 640 8 times, resulting in a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 5651.8
Subtract 640 from 640 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.

Going ahead to step 8:
When dividing 0 by 80, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 5651.8
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 9:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5651.8
Subtracting 0 from 0 leaves us 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.

The quotient of the division is 5651.8, and the remainder is 0.0.
