We're dividing 10721583 by 817 
Let's see how many times 817 fits into 10721583.

Moving on to step 1:
1 divided by 817 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 817

Moving on to step 2:
817 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 817

Moving on to step 3:
The number 817 fits into 107 0 times, leaving a remainder of 107.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 107, we get 107.
Grab the next digit (2) from the dividend, add it to 107, then carry on: 1072 / 817

Moving on to step 4:
If we divide 1072 by 817, we get 1 and a remainder of 255.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 817 away from 1072, we end up with 255.
Include the next digit (1) from the dividend after 255, then repeat: 2551 / 817

Advancing to step 5:
If we divide 2551 by 817, we get 3 and a remainder of 100.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 2451 from 2551 and we're left with 100.
Fetch the next digit (5) from the dividend, attach it to 100 and continue: 1005 / 817

On to step 6:
The number 817 fits into 1005 1 times, leaving a remainder of 188.
The next digit of our result is 1. 
Result so far: 131.0
Deduct 817 from 1005 and we're left with 188.
Bring next digit (8) of the dividend behind the 188 and repeat the process: 1888 / 817

On to step 7:
If we divide 1888 by 817, we get 2 and a remainder of 254.
Put 2 as the next digit of the answer. 
Result so far: 1312.0
Deduct 1634 from 1888 and we're left with 254.
Include the next digit (3) from the dividend after 254, then repeat: 2543 / 817

Let's proceed to step 8:
2543 divided by 817 is 3 with a remainder of 92.
The number 3 becomes the next digit in our result. 
Result so far: 13123.0
If we take 2451 away from 2543, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 9:
The number 817 fits into 920 1 times, leaving a remainder of 103.
Use 1 as the next digit of our solution. 
Result so far: 13123.1
Subtract 817 from 920 to get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 10:
817 can be fit into 1030 1 times, resulting in a remainder of 213.
Put 1 as the next digit of the answer. 
Result so far: 13123.11
The remainder is 213 after subtracting 817 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

In conclusion, the division gives 13123.11 with a balance of 0.213.
