We divide 531358 by 72
We're looking to find how many times 72 goes into 531358.

On to step 1:
When dividing 5 by 72, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 72

Step 2:
72 can be fit into 53 0 times, resulting in a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Append the next digit (1) from the dividend to 53 and continue with: 531 / 72

Step 3:
The number 72 fits into 531 7 times, leaving a remainder of 27.
The next digit of our result is 7. 
Result so far: 7.0
If we take 504 away from 531, we end up with 27.
Take the next digit (3) from the dividend and append it to 27, then repeat: 273 / 72

Step 4:
273 divided by 72 is 3 with a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 73.0
Deduct 216 from 273 and we're left with 57.
Take the next digit (5) from the dividend and append it to 57, then repeat: 575 / 72

Moving on to step 5:
72 can be fit into 575 7 times, resulting in a remainder of 71.
The next digit of our result is 7. 
Result so far: 737.0
Subtracting 504 from 575 leaves us with 71.
Take the next digit (8) from the dividend and append it to 71, then repeat: 718 / 72

Advancing to step 6:
72 can be fit into 718 9 times, resulting in a remainder of 70.
Write down 9 as next digit of the result. 
Result so far: 7379.0
If we take 648 away from 718, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 7:
700 divided by 72 is 9 with a remainder of 52.
The number 9 becomes the next digit in our result. 
Result so far: 7379.9
Subtract 648 from 700 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 8:
When dividing 520 by 72, we get 7 with a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 7379.97
Subtract 504 from 520 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
When dividing 160 by 72, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 7379.972
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
72 goes into 160 2 times with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 7379.9722
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 7379.9722 with a remainder of 0.00016.
