We look at the division of 81012503 by 585 
We want to divide 81012503 by 585.

Going ahead to step 1:
8 divided by 585 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 585

On to step 2:
585 goes into 81 0 times with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Bring next digit (0) of the dividend behind the 81 and repeat the process: 810 / 585

On to step 3:
When dividing 810 by 585, we get 1 with a remainder of 225.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 225 after subtracting 585 from 810.
Take the next digit (1) from the dividend and append it to 225, then repeat: 2251 / 585

Going ahead to step 4:
If we divide 2251 by 585, we get 3 and a remainder of 496.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 1755 from 2251 leaves us with 496.
Take the next digit (2) from the dividend and append it to 496, then repeat: 4962 / 585

On to step 5:
585 can be fit into 4962 8 times, resulting in a remainder of 282.
Put 8 as the next digit of the answer. 
Result so far: 138.0
If we take 4680 away from 4962, we end up with 282.
Append the next digit (5) from the dividend to 282 and continue with: 2825 / 585

Advancing to step 6:
2825 divided by 585 is 4 with a remainder of 485.
Write down 4 as next digit of the result. 
Result so far: 1384.0
If we subtract 2340 from 2825, we get 485.
Fetch the next digit (0) from the dividend, attach it to 485 and continue: 4850 / 585

Let's proceed to step 7:
4850 divided by 585 is 8 with a remainder of 170.
The number 8 becomes the next digit in our result. 
Result so far: 13848.0
If we subtract 4680 from 4850, we get 170.
Grab the next digit (3) from the dividend, add it to 170, then carry on: 1703 / 585

Step 8:
When dividing 1703 by 585, we get 2 with a remainder of 533.
Put 2 as the next digit of the answer. 
Result so far: 138482.0
The remainder is 533 after subtracting 1170 from 1703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Going ahead to step 9:
The number 585 fits into 5330 9 times, leaving a remainder of 65.
The next digit of our result is 9. 
Result so far: 138482.9
The remainder is 65 after subtracting 5265 from 5330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 10:
585 goes into 650 1 times with a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 138482.91
Deduct 585 from 650 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 11:
When dividing 650 by 585, we get 1 with a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 138482.911
The remainder is 65 after subtracting 585 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Our division results in 138482.911 with a remaining 0.0065.
