350868 ÷ 80 
Our goal is to divide 350868 by 80.

Moving on to step 1:
80 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 80

Going ahead to step 2:
80 can be fit into 35 0 times, resulting in a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Append the next digit (0) from the dividend to 35 and continue with: 350 / 80

Let's proceed to step 3:
80 goes into 350 4 times with a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 320 from 350 to get 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 80

Advancing to step 4:
308 divided by 80 is 3 with a remainder of 68.
The next digit of our result is 3. 
Result so far: 43.0
Subtracting 240 from 308 leaves us with 68.
Take the next digit (6) from the dividend and append it to 68, then repeat: 686 / 80

On to step 5:
686 divided by 80 is 8 with a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 438.0
Subtract 640 from 686 to get 46.
Take the next digit (8) from the dividend and append it to 46, then repeat: 468 / 80

Let's proceed to step 6:
80 can be fit into 468 5 times, resulting in a remainder of 68.
Use 5 as the next digit of our solution. 
Result so far: 4385.0
The remainder is 68 after subtracting 400 from 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 7:
The number 80 fits into 680 8 times, leaving a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 4385.8
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.

Advancing to step 8:
If we divide 400 by 80, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 4385.85
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 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4385.85
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.

Going ahead to step 10:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4385.85
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.

After the division, we end up with 4385.85 and a remainder of 0.0.
