We look at the division of 258035 by 81 
We want to divide 258035 by 81.

Going ahead to step 1:
81 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 81

Step 2:
25 divided by 81 is 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 81

On to step 3:
If we divide 258 by 81, we get 3 and a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 15 after subtracting 243 from 258.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 81

On to step 4:
If we divide 150 by 81, we get 1 and a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we subtract 81 from 150, we get 69.
Take the next digit (3) from the dividend and append it to 69, then repeat: 693 / 81

Moving on to step 5:
The number 81 fits into 693 8 times, leaving a remainder of 45.
Write down 8 as next digit of the result. 
Result so far: 318.0
Deduct 648 from 693 and we're left with 45.
Fetch the next digit (5) from the dividend, attach it to 45 and continue: 455 / 81

On to step 6:
81 goes into 455 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 3185.0
If we subtract 405 from 455, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 7:
If we divide 500 by 81, we get 6 and a remainder of 14.
The next digit of our result is 6. 
Result so far: 3185.6
Deduct 486 from 500 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
81 goes into 140 1 times with a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 3185.61
If we subtract 81 from 140, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 9:
590 divided by 81 is 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 3185.617
If we subtract 567 from 590, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 10:
81 can be fit into 230 2 times, resulting in a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 3185.6172
The remainder is 68 after subtracting 162 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 11:
81 goes into 680 8 times with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 3185.61728
The remainder is 32 after subtracting 648 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
81 goes into 320 3 times with a remainder of 77.
The number 3 becomes the next digit in our result. 
Result so far: 3185.617283
If we subtract 243 from 320, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 13:
770 divided by 81 is 9 with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 3185.6172839
Deduct 729 from 770 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 14:
The number 81 fits into 410 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 3185.61728395
Subtracting 405 from 410 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 3185.61728395 and a remainder of 5e-09.
