We divide 213530 by 72
Our goal is to divide 213530 by 72.

Let's proceed to step 1:
2 divided by 72 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 72

Step 2:
If we divide 21 by 72, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 72

On to step 3:
72 can be fit into 213 2 times, resulting in a remainder of 69.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 144 away from 213, we end up with 69.
Take the next digit (5) from the dividend and append it to 69, then repeat: 695 / 72

Step 4:
If we divide 695 by 72, we get 9 and a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
If we subtract 648 from 695, we get 47.
Fetch the next digit (3) from the dividend, attach it to 47 and continue: 473 / 72

Going ahead to step 5:
If we divide 473 by 72, we get 6 and a remainder of 41.
The number 6 becomes the next digit in our result. 
Result so far: 296.0
The remainder is 41 after subtracting 432 from 473.
Take the next digit (0) from the dividend and append it to 41, then repeat: 410 / 72

Step 6:
The number 72 fits into 410 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 2965.0
Subtracting 360 from 410 leaves us 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.

Step 7:
72 can be fit into 500 6 times, resulting in a remainder of 68.
The next digit of our result is 6. 
Result so far: 2965.6
Deduct 432 from 500 and we're left 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.

Going ahead to step 8:
The number 72 fits into 680 9 times, leaving a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 2965.69
Subtract 648 from 680 to get 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 9:
If we divide 320 by 72, we get 4 and a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 2965.694
The remainder is 32 after subtracting 288 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
72 goes into 320 4 times with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 2965.6944
If we subtract 288 from 320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 2965.6944 with a remainder of 0.00032.
