We look at the division of 436310 by 80 
We want to divide 436310 by 80.

Step 1:
The number 80 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 80

Moving on to step 2:
When dividing 43 by 80, we get 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Include the next digit (6) from the dividend after 43, then repeat: 436 / 80

Advancing to step 3:
80 can be fit into 436 5 times, resulting in a remainder of 36.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 400 from 436 to get 36.
Include the next digit (3) from the dividend after 36, then repeat: 363 / 80

Let's proceed to step 4:
The number 80 fits into 363 4 times, leaving a remainder of 43.
Write down 4 as next digit of the result. 
Result so far: 54.0
Subtracting 320 from 363 leaves us with 43.
Append the next digit (1) from the dividend to 43 and continue with: 431 / 80

Advancing to step 5:
431 divided by 80 is 5 with a remainder of 31.
Put 5 as the next digit of the answer. 
Result so far: 545.0
Subtract 400 from 431 to get 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 80

Going ahead to step 6:
80 can be fit into 310 3 times, resulting in a remainder of 70.
Put 3 as the next digit of the answer. 
Result so far: 5453.0
If we subtract 240 from 310, 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 7:
The number 80 fits into 700 8 times, leaving a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 5453.8
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 8:
When dividing 600 by 80, we get 7 with a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 5453.87
If we take 560 away from 600, we end up 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.

Moving on to step 9:
The number 80 fits into 400 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 5453.875
Subtract 400 from 400 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 10:
80 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5453.875
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.

Let's proceed to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 5453.875
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.

Our division results in 5453.875 with a remaining 0.0.
