Let's divide 250987 by 81
We want to figure out the number of times 250987 can be divided by 81.

On to step 1:
2 divided by 81 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.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 81

Moving on to step 2:
When dividing 25 by 81, we get 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 81

Going ahead to step 3:
The number 81 fits into 250 3 times, leaving a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 243 from 250, we get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 81

Advancing to step 4:
The number 81 fits into 79 0 times, leaving a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 30.0
The remainder is 79 after subtracting 0 from 79.
Append the next digit (8) from the dividend to 79 and continue with: 798 / 81

Let's proceed to step 5:
81 goes into 798 9 times with a remainder of 69.
The number 9 becomes the next digit in our result. 
Result so far: 309.0
If we take 729 away from 798, we end up with 69.
Take the next digit (7) from the dividend and append it to 69, then repeat: 697 / 81

Going ahead to step 6:
697 divided by 81 is 8 with a remainder of 49.
Use 8 as the next digit of our solution. 
Result so far: 3098.0
Subtract 648 from 697 to 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.

Step 7:
When dividing 490 by 81, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 3098.6
Subtracting 486 from 490 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
40 divided by 81 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 3098.6
If we take 0 away from 40, we end up 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.

Moving on to step 9:
When dividing 400 by 81, we get 4 with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 3098.604
If we subtract 324 from 400, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 10:
81 can be fit into 760 9 times, resulting in a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 3098.6049
The remainder is 31 after subtracting 729 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 11:
The number 81 fits into 310 3 times, leaving a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 3098.60493
If we subtract 243 from 310, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 12:
The number 81 fits into 670 8 times, leaving a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 3098.604938
The remainder is 22 after subtracting 648 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 13:
When dividing 220 by 81, we get 2 with a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 3098.6049382
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.

Moving on to step 14:
If we divide 580 by 81, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 3098.60493827
If we take 567 away from 580, we end up 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.

The final result is 3098.60493827 with a remainder of 1.3e-08.
