280602 ÷ 9 
We want to divide 280602 by 9.

Advancing to step 1:
The number 9 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 9

Going ahead to step 2:
If we divide 28 by 9, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 27 from 28 to get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 9

Advancing to step 3:
9 goes into 10 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Deduct 9 from 10 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 9

Moving on to step 4:
The number 9 fits into 16 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 311.0
Subtract 9 from 16 to get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 9

On to step 5:
9 goes into 70 7 times with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 3117.0
If we take 63 away from 70, we end up with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 9

Moving on to step 6:
9 can be fit into 72 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 31178.0
If we subtract 72 from 72, 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.

Moving on to step 7:
The number 9 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 31178.0
Subtracting 0 from 0 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.

Step 8:
0 divided by 9 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 31178.0
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 outcome is 31178.0, with a leftover of 0.0.
