We're dividing 349647 by 80 
We want to divide 349647 by 80.

Advancing 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
If we subtract 0 from 3, we get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 80

Step 2:
When dividing 34 by 80, we get 0 with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Fetch the next digit (9) from the dividend, attach it to 34 and continue: 349 / 80

Advancing to step 3:
If we divide 349 by 80, we get 4 and a remainder of 29.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 320 away from 349, we end up with 29.
Include the next digit (6) from the dividend after 29, then repeat: 296 / 80

Going ahead to step 4:
80 goes into 296 3 times with a remainder of 56.
The next digit of our result is 3. 
Result so far: 43.0
If we subtract 240 from 296, we get 56.
Take the next digit (4) from the dividend and append it to 56, then repeat: 564 / 80

Moving on to step 5:
80 can be fit into 564 7 times, resulting in a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 437.0
Subtract 560 from 564 to get 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 80

Going ahead to step 6:
80 goes into 47 0 times with a remainder of 47.
The number 0 becomes the next digit in our result. 
Result so far: 4370.0
Subtract 0 from 47 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 7:
When dividing 470 by 80, we get 5 with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 4370.5
The remainder is 70 after subtracting 400 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
80 can be fit into 700 8 times, resulting in a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 4370.58
If we take 640 away from 700, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
When dividing 600 by 80, we get 7 with a remainder of 40.
The next digit of our result is 7. 
Result so far: 4370.587
If we take 560 away from 600, 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 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4370.5875
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 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4370.5875
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.

Moving on to step 12:
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: 4370.5875
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.

After the division, we end up with 4370.5875 and a remainder of 0.0.
