We're dividing 813223 by 72 
We want to divide 813223 by 72.

Step 1:
8 divided by 72 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 72

Step 2:
72 can be fit into 81 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 72 away from 81, we end up with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 72

On to step 3:
93 divided by 72 is 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 72 from 93, we get 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 72

Step 4:
72 goes into 212 2 times with a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 112.0
The remainder is 68 after subtracting 144 from 212.
Include the next digit (2) from the dividend after 68, then repeat: 682 / 72

Let's proceed to step 5:
When dividing 682 by 72, we get 9 with a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 1129.0
If we subtract 648 from 682, we get 34.
Include the next digit (3) from the dividend after 34, then repeat: 343 / 72

Moving on to step 6:
72 can be fit into 343 4 times, resulting in a remainder of 55.
Put 4 as the next digit of the answer. 
Result so far: 11294.0
If we subtract 288 from 343, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 7:
If we divide 550 by 72, we get 7 and a remainder of 46.
Record the quotient 7 as the next digit in the result. 
Result so far: 11294.7
Deduct 504 from 550 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 8:
The number 72 fits into 460 6 times, leaving a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 11294.76
If we take 432 away from 460, we end up 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.

Step 9:
72 goes into 280 3 times with a remainder of 64.
Record the quotient 3 as the next digit in the result. 
Result so far: 11294.763
Subtracting 216 from 280 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
72 can be fit into 640 8 times, resulting in a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 11294.7638
If we subtract 576 from 640, we 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.

Let's proceed to step 11:
The number 72 fits into 640 8 times, leaving a remainder of 64.
The next digit of our result is 8. 
Result so far: 11294.76388
Subtract 576 from 640 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.

Our division results in 11294.76388 with a remaining 6.4e-05.
