We divide 342512 by 80
Our goal is to divide 342512 by 80.

Advancing to step 1:
When dividing 3 by 80, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 80

Step 2:
The number 80 fits into 34 0 times, leaving 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.
Bring next digit (2) of the dividend behind the 34 and repeat the process: 342 / 80

Let's proceed to step 3:
When dividing 342 by 80, we get 4 with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 22 after subtracting 320 from 342.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 80

On to step 4:
If we divide 225 by 80, we get 2 and a remainder of 65.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Deduct 160 from 225 and we're left with 65.
Fetch the next digit (1) from the dividend, attach it to 65 and continue: 651 / 80

Advancing to step 5:
80 can be fit into 651 8 times, resulting in a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 428.0
If we take 640 away from 651, we end up with 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 80

On to step 6:
80 can be fit into 112 1 times, resulting in a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 4281.0
Subtract 80 from 112 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 7:
If we divide 320 by 80, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4281.4
Subtracting 320 from 320 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.

Going ahead to step 8:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4281.4
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.

Going ahead to step 9:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4281.4
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.

Our division results in 4281.4 with a remaining 0.0.
