258700 divided by 81 
We want to divide 258700 by 81.

Going ahead to step 1:
If we divide 2 by 81, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 81

Step 2:
The number 81 fits into 25 0 times, leaving 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.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 81

Moving 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
If we subtract 243 from 258, we get 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 81

Let's proceed to step 4:
157 divided by 81 is 1 with a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we take 81 away from 157, we end up with 76.
Include the next digit (0) from the dividend after 76, then repeat: 760 / 81

Step 5:
When dividing 760 by 81, we get 9 with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 319.0
Subtract 729 from 760 to get 31.
Take the next digit (0) from the dividend and append it to 31, then repeat: 310 / 81

Let's proceed to step 6:
81 goes into 310 3 times with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 3193.0
The remainder is 67 after subtracting 243 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 7:
81 goes into 670 8 times with a remainder of 22.
The next digit of our result is 8. 
Result so far: 3193.8
Deduct 648 from 670 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
81 can be fit into 220 2 times, resulting in a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 3193.82
Deduct 162 from 220 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 9:
81 goes into 580 7 times with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 3193.827
Subtracting 567 from 580 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 10:
If we divide 130 by 81, we get 1 and a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 3193.8271
If we subtract 81 from 130, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 11:
The number 81 fits into 490 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 3193.82716
Subtract 486 from 490 to 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.

Moving on to step 12:
81 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 3193.82716
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
400 divided by 81 is 4 with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 3193.8271604
If we take 324 away from 400, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 14:
760 divided by 81 is 9 with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 3193.82716049
If we take 729 away from 760, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Our division results in 3193.82716049 with a remaining 3.1e-08.
