450631 ÷ 80 
We're looking to find how many times 80 goes into 450631.

On to step 1:
If we divide 4 by 80, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 80

On to step 2:
45 divided by 80 is 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Fetch the next digit (0) from the dividend, attach it to 45 and continue: 450 / 80

On to step 3:
80 can be fit into 450 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 400 from 450 to get 50.
Append the next digit (6) from the dividend to 50 and continue with: 506 / 80

Let's proceed to step 4:
The number 80 fits into 506 6 times, leaving a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 56.0
If we subtract 480 from 506, we get 26.
Bring next digit (3) of the dividend behind the 26 and repeat the process: 263 / 80

Advancing to step 5:
263 divided by 80 is 3 with a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 563.0
Deduct 240 from 263 and we're left with 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 80

Step 6:
80 goes into 231 2 times with a remainder of 71.
Use 2 as the next digit of our solution. 
Result so far: 5632.0
Subtract 160 from 231 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 7:
710 divided by 80 is 8 with a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 5632.8
If we take 640 away from 710, we end up with 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:
When dividing 700 by 80, we get 8 with a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 5632.88
If we subtract 640 from 700, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 5632.88 with a remaining 0.06.
