Let's divide 225649 by 81
Let's see how many times 81 fits into 225649.

On to step 1:
When dividing 2 by 81, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 81

On to step 2:
When dividing 22 by 81, we get 0 with a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 22 and we're left with 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 81

Moving on to step 3:
81 goes into 225 2 times with a remainder of 63.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 162 from 225 to get 63.
Fetch the next digit (6) from the dividend, attach it to 63 and continue: 636 / 81

Going ahead to step 4:
81 can be fit into 636 7 times, resulting in a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 27.0
If we subtract 567 from 636, we get 69.
Fetch the next digit (4) from the dividend, attach it to 69 and continue: 694 / 81

Advancing to step 5:
81 goes into 694 8 times with a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 278.0
If we take 648 away from 694, we end up with 46.
Append the next digit (9) from the dividend to 46 and continue with: 469 / 81

Going ahead to step 6:
If we divide 469 by 81, we get 5 and a remainder of 64.
Use 5 as the next digit of our solution. 
Result so far: 2785.0
The remainder is 64 after subtracting 405 from 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 7:
When dividing 640 by 81, we get 7 with a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 2785.7
If we take 567 away from 640, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 8:
81 can be fit into 730 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 2785.79
Subtract 729 from 730 to get 1.
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 9:
The number 81 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 2785.79
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
81 goes into 100 1 times with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 2785.7901
Subtracting 81 from 100 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 11:
81 goes into 190 2 times with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 2785.79012
Subtract 162 from 190 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
If we divide 280 by 81, we get 3 and a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 2785.790123
Deduct 243 from 280 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 13:
81 goes into 370 4 times with a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 2785.7901234
Subtract 324 from 370 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 14:
If we divide 460 by 81, we get 5 and a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 2785.79012345
The remainder is 55 after subtracting 405 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

After the division, we end up with 2785.79012345 and a remainder of 5.5e-08.
