303720 divided by 81 
Let's see how many times 81 fits into 303720.

On to step 1:
81 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 81

Going ahead to step 2:
30 divided by 81 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 81

Going ahead to step 3:
If we divide 303 by 81, we get 3 and a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 243 from 303 leaves us with 60.
Include the next digit (7) from the dividend after 60, then repeat: 607 / 81

Going ahead to step 4:
607 divided by 81 is 7 with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Subtract 567 from 607 to get 40.
Append the next digit (2) from the dividend to 40 and continue with: 402 / 81

Going ahead to step 5:
When dividing 402 by 81, we get 4 with a remainder of 78.
The next digit of our result is 4. 
Result so far: 374.0
The remainder is 78 after subtracting 324 from 402.
Fetch the next digit (0) from the dividend, attach it to 78 and continue: 780 / 81

Step 6:
If we divide 780 by 81, we get 9 and a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 3749.0
The remainder is 51 after subtracting 729 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 7:
81 can be fit into 510 6 times, resulting in a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 3749.6
The remainder is 24 after subtracting 486 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
When dividing 240 by 81, we get 2 with a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 3749.62
If we take 162 away from 240, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 9:
780 divided by 81 is 9 with a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 3749.629
Subtract 729 from 780 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 10:
The number 81 fits into 510 6 times, leaving a remainder of 24.
The next digit of our result is 6. 
Result so far: 3749.6296
If we subtract 486 from 510, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
81 can be fit into 240 2 times, resulting in a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 3749.62962
Subtract 162 from 240 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 12:
If we divide 780 by 81, we get 9 and a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 3749.629629
If we take 729 away from 780, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 13:
When dividing 510 by 81, we get 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 3749.6296296
Subtract 486 from 510 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 14:
If we divide 240 by 81, we get 2 and a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 3749.62962962
Deduct 162 from 240 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Our division results in 3749.62962962 with a remaining 7.8e-08.
