We're dividing 234428 by 80 
We want to divide 234428 by 80.

On to step 1:
80 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 80

Advancing to step 2:
23 divided by 80 is 0 with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 80

Moving on to step 3:
80 can be fit into 234 2 times, resulting in a remainder of 74.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 160 from 234 and we're left with 74.
Bring next digit (4) of the dividend behind the 74 and repeat the process: 744 / 80

Advancing to step 4:
The number 80 fits into 744 9 times, leaving a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Subtract 720 from 744 to get 24.
Fetch the next digit (2) from the dividend, attach it to 24 and continue: 242 / 80

On to step 5:
If we divide 242 by 80, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 293.0
If we take 240 away from 242, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 80

On to step 6:
28 divided by 80 is 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 2930.0
Subtracting 0 from 28 leaves us with 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 can be fit into 280 3 times, resulting in a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 2930.3
Subtract 240 from 280 to 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.

Moving on to 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: 2930.35
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.

On to step 9:
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: 2930.35
Subtract 0 from 0 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.

Going ahead to step 10:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2930.35
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 2930.35, and the remainder is 0.0.
