221456 ÷ 81 
We want to figure out the number of times 221456 can be divided by 81.

On to step 1:
81 can be fit into 2 0 times, resulting in 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.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 81

Let's proceed to step 2:
The number 81 fits into 22 0 times, leaving a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 22 to get 22.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 81

Moving on to step 3:
The number 81 fits into 221 2 times, leaving a remainder of 59.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 162 from 221 leaves us with 59.
Bring next digit (4) of the dividend behind the 59 and repeat the process: 594 / 81

Step 4:
594 divided by 81 is 7 with a remainder of 27.
The next digit of our result is 7. 
Result so far: 27.0
Subtract 567 from 594 to get 27.
Bring next digit (5) of the dividend behind the 27 and repeat the process: 275 / 81

Step 5:
The number 81 fits into 275 3 times, leaving a remainder of 32.
The next digit of our result is 3. 
Result so far: 273.0
If we subtract 243 from 275, we get 32.
Include the next digit (6) from the dividend after 32, then repeat: 326 / 81

Going ahead to step 6:
81 goes into 326 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 2734.0
Subtracting 324 from 326 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
81 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 2734.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
The number 81 fits into 200 2 times, leaving a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 2734.02
Deduct 162 from 200 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
When dividing 380 by 81, we get 4 with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 2734.024
If we take 324 away from 380, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
When dividing 560 by 81, we get 6 with a remainder of 74.
Put 6 as the next digit of the answer. 
Result so far: 2734.0246
If we take 486 away from 560, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 11:
81 can be fit into 740 9 times, resulting in a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 2734.02469
Subtracting 729 from 740 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 12:
When dividing 110 by 81, we get 1 with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 2734.024691
Deduct 81 from 110 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 13:
When dividing 290 by 81, we get 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 2734.0246913
If we subtract 243 from 290, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 14:
81 goes into 470 5 times with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 2734.02469135
Subtract 405 from 470 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 2734.02469135 with a remainder of 6.5e-08.
