257998 ÷ 9 
We want to divide 257998 by 9.

Moving on to step 1:
2 divided by 9 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 9

Going ahead to step 2:
9 goes into 25 2 times with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 18 away from 25, we end up with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 9

Advancing to step 3:
When dividing 77 by 9, we get 8 with a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 28.0
The remainder is 5 after subtracting 72 from 77.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 9

Let's proceed to step 4:
9 can be fit into 59 6 times, resulting in a remainder of 5.
The next digit of our result is 6. 
Result so far: 286.0
The remainder is 5 after subtracting 54 from 59.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 9

Moving on to step 5:
9 goes into 59 6 times with a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 2866.0
The remainder is 5 after subtracting 54 from 59.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 9

Advancing to step 6:
58 divided by 9 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 28666.0
If we take 54 away from 58, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
9 goes into 40 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 28666.4
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
When dividing 40 by 9, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 28666.44
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 28666.44 with a remaining 0.004.
