We divide 434916 by 80
We're looking to find how many times 80 goes into 434916.

Step 1:
80 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 80

Going ahead to step 2:
The number 80 fits into 43 0 times, leaving a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Bring next digit (4) of the dividend behind the 43 and repeat the process: 434 / 80

On to step 3:
80 can be fit into 434 5 times, resulting in a remainder of 34.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 400 from 434 leaves us with 34.
Take the next digit (9) from the dividend and append it to 34, then repeat: 349 / 80

Going ahead to step 4:
If we divide 349 by 80, we get 4 and a remainder of 29.
The next digit of our result is 4. 
Result so far: 54.0
Deduct 320 from 349 and we're left with 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 80

On to step 5:
The number 80 fits into 291 3 times, leaving a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 543.0
Subtract 240 from 291 to get 51.
Append the next digit (6) from the dividend to 51 and continue with: 516 / 80

Let's proceed to step 6:
The number 80 fits into 516 6 times, leaving a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 5436.0
Subtracting 480 from 516 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 7:
If we divide 360 by 80, we get 4 and a remainder of 40.
The next digit of our result is 4. 
Result so far: 5436.4
If we take 320 away from 360, 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 8:
80 goes into 400 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5436.45
Subtracting 400 from 400 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.

Advancing to step 9:
80 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5436.45
If we take 0 away from 0, 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.

Let's proceed to step 10:
0 divided by 80 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5436.45
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 quotient of the division is 5436.45, and the remainder is 0.0.
