Let's divide 306505 by 81
Let's see how many times 81 fits into 306505.

Let's proceed to step 1:
3 divided by 81 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 81

Let's proceed to step 2:
The number 81 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 81

Let's proceed to step 3:
81 can be fit into 306 3 times, resulting in a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 243 from 306 and we're left with 63.
Grab the next digit (5) from the dividend, add it to 63, then carry on: 635 / 81

Going ahead to step 4:
If we divide 635 by 81, we get 7 and a remainder of 68.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Deduct 567 from 635 and we're left with 68.
Append the next digit (0) from the dividend to 68 and continue with: 680 / 81

Let's proceed to step 5:
81 can be fit into 680 8 times, resulting in a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 378.0
If we take 648 away from 680, we end up with 32.
Append the next digit (5) from the dividend to 32 and continue with: 325 / 81

Moving on to step 6:
325 divided by 81 is 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 3784.0
Subtracting 324 from 325 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
The number 81 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 3784.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
81 can be fit into 100 1 times, resulting in a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 3784.01
Subtracting 81 from 100 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
81 can be fit into 190 2 times, resulting in a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 3784.012
Deduct 162 from 190 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
If we divide 280 by 81, we get 3 and a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 3784.0123
If we subtract 243 from 280, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 11:
The number 81 fits into 370 4 times, leaving a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 3784.01234
If we subtract 324 from 370, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 12:
81 can be fit into 460 5 times, resulting in a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 3784.012345
The remainder is 55 after subtracting 405 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 13:
81 goes into 550 6 times with a remainder of 64.
The next digit of our result is 6. 
Result so far: 3784.0123456
Subtract 486 from 550 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 14:
The number 81 fits into 640 7 times, leaving a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 3784.01234567
Subtracting 567 from 640 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

In conclusion, the division gives 3784.01234567 with a balance of 7.3e-08.
