We divide 252221 by 81
We're looking to find how many times 81 goes into 252221.

Moving on to step 1:
The number 81 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 81

Let's proceed to step 2:
If we divide 25 by 81, we get 0 and a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Append the next digit (2) from the dividend to 25 and continue with: 252 / 81

Moving on to step 3:
81 goes into 252 3 times with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 9 after subtracting 243 from 252.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 81

Moving on to step 4:
81 goes into 92 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 31.0
The remainder is 11 after subtracting 81 from 92.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 81

Step 5:
When dividing 112 by 81, we get 1 with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 311.0
If we take 81 away from 112, we end up with 31.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 81

Step 6:
311 divided by 81 is 3 with a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 3113.0
Deduct 243 from 311 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 7:
680 divided by 81 is 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 3113.8
Subtracting 648 from 680 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 8:
If we divide 320 by 81, we get 3 and a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 3113.83
The remainder is 77 after subtracting 243 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 9:
81 can be fit into 770 9 times, resulting in a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 3113.839
Subtracting 729 from 770 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 10:
If we divide 410 by 81, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 3113.8395
Subtract 405 from 410 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
81 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 3113.8395
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
The number 81 fits into 500 6 times, leaving a remainder of 14.
The next digit of our result is 6. 
Result so far: 3113.839506
If we subtract 486 from 500, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 13:
140 divided by 81 is 1 with a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 3113.8395061
The remainder is 59 after subtracting 81 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 14:
590 divided by 81 is 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 3113.83950617
If we take 567 away from 590, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Our division results in 3113.83950617 with a remaining 2.3e-08.
