430556 ÷ 80 
Let's see how many times 80 fits into 430556.

Advancing to step 1:
80 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 80

Going ahead to step 2:
43 divided by 80 is 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Grab the next digit (0) from the dividend, add it to 43, then carry on: 430 / 80

Moving on to step 3:
If we divide 430 by 80, we get 5 and a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 400 from 430 and we're left with 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 80

Advancing to step 4:
If we divide 305 by 80, we get 3 and a remainder of 65.
Use 3 as the next digit of our solution. 
Result so far: 53.0
If we subtract 240 from 305, we get 65.
Take the next digit (5) from the dividend and append it to 65, then repeat: 655 / 80

Advancing to step 5:
When dividing 655 by 80, we get 8 with a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 538.0
If we subtract 640 from 655, we get 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 80

Let's proceed to step 6:
The number 80 fits into 156 1 times, leaving a remainder of 76.
Write down 1 as next digit of the result. 
Result so far: 5381.0
If we subtract 80 from 156, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 7:
If we divide 760 by 80, we get 9 and a remainder of 40.
Record the quotient 9 as the next digit in the result. 
Result so far: 5381.9
Subtracting 720 from 760 leaves us 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: 5381.95
If we subtract 400 from 400, 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.

Moving on to step 9:
0 divided by 80 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 5381.95
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.

Step 10:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5381.95
The remainder is 0 after subtracting 0 from 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 5381.95, and the remainder is 0.0.
