342812 divided by 80 
Our goal is to divide 342812 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
Subtract 0 from 3 to get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 80

Moving on to step 2:
80 can be fit into 34 0 times, resulting in a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Take the next digit (2) from the dividend and append it to 34, then repeat: 342 / 80

On to step 3:
80 goes into 342 4 times with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 320 away from 342, we end up with 22.
Take the next digit (8) from the dividend and append it to 22, then repeat: 228 / 80

On to step 4:
When dividing 228 by 80, we get 2 with a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Subtract 160 from 228 to get 68.
Take the next digit (1) from the dividend and append it to 68, then repeat: 681 / 80

Step 5:
If we divide 681 by 80, we get 8 and a remainder of 41.
The number 8 becomes the next digit in our result. 
Result so far: 428.0
The remainder is 41 after subtracting 640 from 681.
Include the next digit (2) from the dividend after 41, then repeat: 412 / 80

Moving on to step 6:
80 can be fit into 412 5 times, resulting in a remainder of 12.
Record the quotient 5 as the next digit in the result. 
Result so far: 4285.0
The remainder is 12 after subtracting 400 from 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
80 can be fit into 120 1 times, resulting in a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 4285.1
Subtracting 80 from 120 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.

Step 8:
The number 80 fits into 400 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 4285.15
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.

Advancing to step 9:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4285.15
Deduct 0 from 0 and we're left 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.

Let's proceed to step 10:
0 divided by 80 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4285.15
Deduct 0 from 0 and we're left 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 result is 4285.15 with a remainder of 0.0.
