We divide 258045 by 31
Our goal is to divide 258045 by 31.

Going ahead to step 1:
2 divided by 31 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 31

Moving on to step 2:
The number 31 fits into 25 0 times, leaving a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 31

Step 3:
258 divided by 31 is 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 248 from 258 to get 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 31

On to step 4:
If we divide 100 by 31, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
Subtracting 93 from 100 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 31

Going ahead to step 5:
31 goes into 74 2 times with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 832.0
Subtracting 62 from 74 leaves us with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 31

Going ahead to step 6:
The number 31 fits into 125 4 times, leaving a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 8324.0
The remainder is 1 after subtracting 124 from 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
31 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 8324.0
The remainder is 10 after subtracting 0 from 10.
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:
When dividing 100 by 31, we get 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 8324.03
The remainder is 7 after subtracting 93 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 9:
70 divided by 31 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 8324.032
If we subtract 62 from 70, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
If we divide 80 by 31, we get 2 and a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 8324.0322
If we subtract 62 from 80, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 8324.0322 with a remainder of 0.00018.
