Let's divide 506565 by 81
Let's see how many times 81 fits into 506565.

Advancing to step 1:
81 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 81

On to step 2:
When dividing 50 by 81, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Bring next digit (6) of the dividend behind the 50 and repeat the process: 506 / 81

Let's proceed to step 3:
When dividing 506 by 81, we get 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 486 away from 506, we end up with 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 81

Advancing to step 4:
The number 81 fits into 205 2 times, leaving a remainder of 43.
The next digit of our result is 2. 
Result so far: 62.0
Subtract 162 from 205 to get 43.
Include the next digit (6) from the dividend after 43, then repeat: 436 / 81

Let's proceed to step 5:
If we divide 436 by 81, we get 5 and a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 625.0
Deduct 405 from 436 and we're left with 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 81

Advancing to step 6:
315 divided by 81 is 3 with a remainder of 72.
Put 3 as the next digit of the answer. 
Result so far: 6253.0
The remainder is 72 after subtracting 243 from 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 7:
When dividing 720 by 81, we get 8 with a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 6253.8
Subtract 648 from 720 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 8:
81 can be fit into 720 8 times, resulting in a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 6253.88
Deduct 648 from 720 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 6253.88 with a remaining 0.072.
