We look at the division of 430028 by 80 
We want to figure out the number of times 430028 can be divided by 80.

Going ahead to step 1:
The number 80 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 80

Step 2:
80 goes into 43 0 times with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 80

Advancing to step 3:
80 can be fit into 430 5 times, resulting in a remainder of 30.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 400 from 430 leaves us with 30.
Fetch the next digit (0) from the dividend, attach it to 30 and continue: 300 / 80

Advancing to step 4:
80 can be fit into 300 3 times, resulting in a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 53.0
The remainder is 60 after subtracting 240 from 300.
Fetch the next digit (2) from the dividend, attach it to 60 and continue: 602 / 80

Advancing to step 5:
602 divided by 80 is 7 with a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 537.0
If we subtract 560 from 602, we get 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 80

Advancing to step 6:
80 goes into 428 5 times with a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 5375.0
If we subtract 400 from 428, 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.

Advancing to step 7:
280 divided by 80 is 3 with a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 5375.3
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.

On to step 8:
400 divided by 80 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5375.35
Deduct 400 from 400 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.

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: 5375.35
The remainder is 0 after subtracting 0 from 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:
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: 5375.35
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.

The final result is 5375.35 with a remainder of 0.0.
