We look at the division of 502988 by 81 
We're looking to find how many times 81 goes into 502988.

Step 1:
5 divided by 81 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 81

Step 2:
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: 0.0
Subtract 0 from 50 to get 50.
Fetch the next digit (2) from the dividend, attach it to 50 and continue: 502 / 81

On to step 3:
502 divided by 81 is 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 486 from 502 and we're left with 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 81

Step 4:
When dividing 169 by 81, we get 2 with a remainder of 7.
The next digit of our result is 2. 
Result so far: 62.0
Subtract 162 from 169 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 81

Let's proceed to step 5:
81 can be fit into 78 0 times, resulting in a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 620.0
The remainder is 78 after subtracting 0 from 78.
Include the next digit (8) from the dividend after 78, then repeat: 788 / 81

On to step 6:
If we divide 788 by 81, we get 9 and a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 6209.0
Subtract 729 from 788 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 7:
81 goes into 590 7 times with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 6209.7
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.

Moving on to step 8:
230 divided by 81 is 2 with a remainder of 68.
The next digit of our result is 2. 
Result so far: 6209.72
Subtracting 162 from 230 leaves us 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.

On to step 9:
680 divided by 81 is 8 with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 6209.728
Deduct 648 from 680 and we're left 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.

Let's proceed to step 10:
81 goes into 320 3 times with a remainder of 77.
Put 3 as the next digit of the answer. 
Result so far: 6209.7283
Deduct 243 from 320 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 11:
When dividing 770 by 81, we get 9 with a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 6209.72839
Deduct 729 from 770 and we're left 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.

Going ahead to step 12:
81 goes into 410 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 6209.728395
If we subtract 405 from 410, we 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 13:
When dividing 50 by 81, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 6209.728395
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.

Advancing to step 14:
81 can be fit into 500 6 times, resulting in a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 6209.72839506
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.

Our division results in 6209.72839506 with a remaining 1.4e-08.
