Let's divide 343788 by 80
We want to figure out the number of times 343788 can be divided by 80.

Going ahead to step 1:
If we divide 3 by 80, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 80

Advancing to step 2:
34 divided by 80 is 0 with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Fetch the next digit (3) from the dividend, attach it to 34 and continue: 343 / 80

Advancing to step 3:
343 divided by 80 is 4 with a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 320 from 343, we get 23.
Append the next digit (7) from the dividend to 23 and continue with: 237 / 80

Let's proceed to step 4:
80 can be fit into 237 2 times, resulting in a remainder of 77.
The next digit of our result is 2. 
Result so far: 42.0
The remainder is 77 after subtracting 160 from 237.
Bring next digit (8) of the dividend behind the 77 and repeat the process: 778 / 80

Advancing to step 5:
80 can be fit into 778 9 times, resulting in a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 429.0
If we subtract 720 from 778, we get 58.
Fetch the next digit (8) from the dividend, attach it to 58 and continue: 588 / 80

Step 6:
When dividing 588 by 80, we get 7 with a remainder of 28.
The next digit of our result is 7. 
Result so far: 4297.0
If we subtract 560 from 588, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
80 goes into 280 3 times with a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 4297.3
If we take 240 away from 280, 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.

Going ahead to step 8:
80 goes into 400 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 4297.35
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.

Step 9:
When dividing 0 by 80, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4297.35
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.

Advancing to step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4297.35
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.

After the division, we end up with 4297.35 and a remainder of 0.0.
