258500 ÷ 81 
Let's see how many times 81 fits into 258500.

Moving on to step 1:
If we divide 2 by 81, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 81

Moving on to step 2:
If we divide 25 by 81, we get 0 and a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 81

Let's proceed to step 3:
81 can be fit into 258 3 times, resulting in a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 243 from 258 leaves us with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 81

On to step 4:
155 divided by 81 is 1 with a remainder of 74.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtracting 81 from 155 leaves us with 74.
Bring next digit (0) of the dividend behind the 74 and repeat the process: 740 / 81

On to step 5:
When dividing 740 by 81, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 319.0
The remainder is 11 after subtracting 729 from 740.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 81

Let's proceed to step 6:
110 divided by 81 is 1 with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 3191.0
Subtract 81 from 110 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
When dividing 290 by 81, we get 3 with a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 3191.3
Subtracting 243 from 290 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 8:
When dividing 470 by 81, we get 5 with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 3191.35
If we take 405 away from 470, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 9:
81 goes into 650 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 3191.358
Deduct 648 from 650 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
The number 81 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 3191.358
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
81 can be fit into 200 2 times, resulting in a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 3191.35802
Subtract 162 from 200 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 12:
380 divided by 81 is 4 with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 3191.358024
The remainder is 56 after subtracting 324 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 13:
81 can be fit into 560 6 times, resulting in a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 3191.3580246
If we subtract 486 from 560, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 14:
When dividing 740 by 81, we get 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 3191.35802469
If we subtract 729 from 740, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Our division results in 3191.35802469 with a remaining 1.1e-08.
