423268 ÷ 80 
Let's see how many times 80 fits into 423268.

Let's proceed to step 1:
80 goes into 4 0 times with 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.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 80

Step 2:
The number 80 fits into 42 0 times, leaving a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Fetch the next digit (3) from the dividend, attach it to 42 and continue: 423 / 80

Going ahead to step 3:
80 can be fit into 423 5 times, resulting in a remainder of 23.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 400 from 423 leaves us with 23.
Fetch the next digit (2) from the dividend, attach it to 23 and continue: 232 / 80

On to step 4:
80 can be fit into 232 2 times, resulting in a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 52.0
If we subtract 160 from 232, we get 72.
Grab the next digit (6) from the dividend, add it to 72, then carry on: 726 / 80

On to step 5:
When dividing 726 by 80, we get 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 529.0
If we subtract 720 from 726, we get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 80

Step 6:
80 goes into 68 0 times with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 5290.0
Subtracting 0 from 68 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 7:
When dividing 680 by 80, we get 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 5290.8
Subtracting 640 from 680 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.

Let's proceed to step 8:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5290.85
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.

On to step 9:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5290.85
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.

Going ahead to step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5290.85
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.

The final outcome is 5290.85, with a leftover of 0.0.
