242840 ÷ 80 
We want to figure out the number of times 242840 can be divided by 80.

Let's proceed to step 1:
2 divided by 80 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 80

Advancing to step 2:
If we divide 24 by 80, we get 0 and a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 24 leaves us with 24.
Bring next digit (2) of the dividend behind the 24 and repeat the process: 242 / 80

Going ahead to step 3:
242 divided by 80 is 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 240 from 242, we get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 80

On to step 4:
When dividing 28 by 80, we get 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 30.0
Deduct 0 from 28 and we're left with 28.
Append the next digit (4) from the dividend to 28 and continue with: 284 / 80

Going ahead to step 5:
When dividing 284 by 80, we get 3 with a remainder of 44.
Record the quotient 3 as the next digit in the result. 
Result so far: 303.0
If we subtract 240 from 284, we get 44.
Fetch the next digit (0) from the dividend, attach it to 44 and continue: 440 / 80

Going ahead to step 6:
The number 80 fits into 440 5 times, leaving a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 3035.0
If we subtract 400 from 440, we get 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 7:
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: 3035.5
If we take 400 away from 400, 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.

Step 8:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3035.5
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.

Advancing to step 9:
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: 3035.5
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.

The quotient of the division is 3035.5, and the remainder is 0.0.
