We divide 257920 by 30
We want to figure out the number of times 257920 can be divided by 30.

Moving on to step 1:
When dividing 2 by 30, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 30

On to step 2:
30 goes into 25 0 times with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Include the next digit (7) from the dividend after 25, then repeat: 257 / 30

Step 3:
The number 30 fits into 257 8 times, leaving a remainder of 17.
The next digit of our result is 8. 
Result so far: 8.0
If we take 240 away from 257, we end up with 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 30

Step 4:
30 goes into 179 5 times with a remainder of 29.
Put 5 as the next digit of the answer. 
Result so far: 85.0
If we take 150 away from 179, we end up with 29.
Bring next digit (2) of the dividend behind the 29 and repeat the process: 292 / 30

Step 5:
When dividing 292 by 30, we get 9 with a remainder of 22.
The next digit of our result is 9. 
Result so far: 859.0
The remainder is 22 after subtracting 270 from 292.
Append the next digit (0) from the dividend to 22 and continue with: 220 / 30

Advancing to step 6:
220 divided by 30 is 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 8597.0
Subtracting 210 from 220 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 8597.3
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
30 goes into 100 3 times with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 8597.33
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 8597.33, with a leftover of 0.01.
