We're dividing 436263 by 80 
Let's see how many times 80 fits into 436263.

Going ahead to step 1:
If we divide 4 by 80, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 80

On to step 2:
If we divide 43 by 80, we get 0 and a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Include the next digit (6) from the dividend after 43, then repeat: 436 / 80

On to step 3:
436 divided by 80 is 5 with a remainder of 36.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 36 after subtracting 400 from 436.
Fetch the next digit (2) from the dividend, attach it to 36 and continue: 362 / 80

Moving on to step 4:
80 can be fit into 362 4 times, resulting in a remainder of 42.
The next digit of our result is 4. 
Result so far: 54.0
Subtracting 320 from 362 leaves us with 42.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 80

Step 5:
If we divide 426 by 80, we get 5 and a remainder of 26.
The next digit of our result is 5. 
Result so far: 545.0
Subtract 400 from 426 to get 26.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 80

Advancing to step 6:
The number 80 fits into 263 3 times, leaving a remainder of 23.
The next digit of our result is 3. 
Result so far: 5453.0
Deduct 240 from 263 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
230 divided by 80 is 2 with a remainder of 70.
Put 2 as the next digit of the answer. 
Result so far: 5453.2
If we subtract 160 from 230, we 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.

Advancing to step 8:
700 divided by 80 is 8 with a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 5453.28
Deduct 640 from 700 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
600 divided by 80 is 7 with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 5453.287
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5453.2875
If we take 400 away from 400, we end up 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.

Moving on to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5453.2875
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.

Advancing to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5453.2875
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.

After the division, we end up with 5453.2875 and a remainder of 0.0.
