We look at the division of 225799 by 81 
We want to figure out the number of times 225799 can be divided by 81.

Going ahead to step 1:
81 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 81

Let's proceed to step 2:
22 divided by 81 is 0 with a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 22 and we're left with 22.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 81

Going ahead to step 3:
81 can be fit into 225 2 times, resulting in a remainder of 63.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 162 from 225 to get 63.
Take the next digit (7) from the dividend and append it to 63, then repeat: 637 / 81

Step 4:
81 can be fit into 637 7 times, resulting in a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtracting 567 from 637 leaves us with 70.
Take the next digit (9) from the dividend and append it to 70, then repeat: 709 / 81

Step 5:
81 can be fit into 709 8 times, resulting in a remainder of 61.
Write down 8 as next digit of the result. 
Result so far: 278.0
If we subtract 648 from 709, we get 61.
Fetch the next digit (9) from the dividend, attach it to 61 and continue: 619 / 81

Going ahead to step 6:
81 can be fit into 619 7 times, resulting in a remainder of 52.
The next digit of our result is 7. 
Result so far: 2787.0
The remainder is 52 after subtracting 567 from 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 7:
If we divide 520 by 81, we get 6 and a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 2787.6
Deduct 486 from 520 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
340 divided by 81 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 2787.64
The remainder is 16 after subtracting 324 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
160 divided by 81 is 1 with a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 2787.641
The remainder is 79 after subtracting 81 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 10:
81 can be fit into 790 9 times, resulting in a remainder of 61.
The next digit of our result is 9. 
Result so far: 2787.6419
If we subtract 729 from 790, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 11:
When dividing 610 by 81, we get 7 with a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 2787.64197
Deduct 567 from 610 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 12:
The number 81 fits into 430 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 2787.641975
The remainder is 25 after subtracting 405 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 13:
The number 81 fits into 250 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 2787.6419753
The remainder is 7 after subtracting 243 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 14:
If we divide 70 by 81, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 2787.6419753
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 2787.6419753, with a leftover of 7e-08.
