284273 ÷ 81 
We're looking to find how many times 81 goes into 284273.

Step 1:
81 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 81

Advancing to step 2:
If we divide 28 by 81, we get 0 and a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 81

Moving on to step 3:
81 goes into 284 3 times with a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 243 away from 284, we end up with 41.
Include the next digit (2) from the dividend after 41, then repeat: 412 / 81

Going ahead to step 4:
81 goes into 412 5 times with a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 35.0
If we take 405 away from 412, we end up with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 81

Advancing to step 5:
77 divided by 81 is 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 350.0
If we subtract 0 from 77, we get 77.
Append the next digit (3) from the dividend to 77 and continue with: 773 / 81

Let's proceed to step 6:
If we divide 773 by 81, we get 9 and a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 3509.0
Subtracting 729 from 773 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 7:
81 goes into 440 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 3509.5
If we subtract 405 from 440, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
When dividing 350 by 81, we get 4 with a remainder of 26.
The next digit of our result is 4. 
Result so far: 3509.54
Deduct 324 from 350 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
If we divide 260 by 81, we get 3 and a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 3509.543
Subtracting 243 from 260 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 10:
170 divided by 81 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 3509.5432
Deduct 162 from 170 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
If we divide 80 by 81, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 3509.5432
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
81 goes into 800 9 times with a remainder of 71.
The next digit of our result is 9. 
Result so far: 3509.543209
Subtract 729 from 800 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 13:
The number 81 fits into 710 8 times, leaving a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 3509.5432098
Deduct 648 from 710 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 14:
If we divide 620 by 81, we get 7 and a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 3509.54320987
Subtracting 567 from 620 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The final outcome is 3509.54320987, with a leftover of 5.3e-08.
