344866 ÷ 80 
We want to divide 344866 by 80.

On to step 1:
The number 80 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 80

Step 2:
80 can be fit into 34 0 times, resulting in a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Include the next digit (4) from the dividend after 34, then repeat: 344 / 80

Going ahead to step 3:
80 can be fit into 344 4 times, resulting in a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 320 from 344 leaves us with 24.
Append the next digit (8) from the dividend to 24 and continue with: 248 / 80

Going ahead to step 4:
If we divide 248 by 80, we get 3 and a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Subtracting 240 from 248 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 80

Let's proceed to step 5:
80 can be fit into 86 1 times, resulting in a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 431.0
The remainder is 6 after subtracting 80 from 86.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 80

Let's proceed to step 6:
The number 80 fits into 66 0 times, leaving a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 4310.0
If we subtract 0 from 66, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 7:
80 can be fit into 660 8 times, resulting in a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 4310.8
If we take 640 away from 660, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
When dividing 200 by 80, we get 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 4310.82
If we take 160 away from 200, 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.

On to step 9:
80 goes into 400 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 4310.825
If we take 400 away from 400, 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.

Step 10:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4310.825
Subtract 0 from 0 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.

Advancing to step 11:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4310.825
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.

After the division, we end up with 4310.825 and a remainder of 0.0.
