Let's divide 72179069 by 531
We want to figure out the number of times 72179069 can be divided by 531.

Step 1:
If we divide 7 by 531, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 531

Going ahead to step 2:
When dividing 72 by 531, we get 0 with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Append the next digit (1) from the dividend to 72 and continue with: 721 / 531

Going ahead to step 3:
When dividing 721 by 531, we get 1 with a remainder of 190.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 531 from 721 and we're left with 190.
Bring next digit (7) of the dividend behind the 190 and repeat the process: 1907 / 531

Going ahead to step 4:
If we divide 1907 by 531, we get 3 and a remainder of 314.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 314 after subtracting 1593 from 1907.
Fetch the next digit (9) from the dividend, attach it to 314 and continue: 3149 / 531

Let's proceed to step 5:
If we divide 3149 by 531, we get 5 and a remainder of 494.
Use 5 as the next digit of our solution. 
Result so far: 135.0
Deduct 2655 from 3149 and we're left with 494.
Append the next digit (0) from the dividend to 494 and continue with: 4940 / 531

Moving on to step 6:
If we divide 4940 by 531, we get 9 and a remainder of 161.
Put 9 as the next digit of the answer. 
Result so far: 1359.0
Deduct 4779 from 4940 and we're left with 161.
Take the next digit (6) from the dividend and append it to 161, then repeat: 1616 / 531

Going ahead to step 7:
When dividing 1616 by 531, we get 3 with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 13593.0
Deduct 1593 from 1616 and we're left with 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 531

Step 8:
If we divide 239 by 531, we get 0 and a remainder of 239.
The next digit of our result is 0. 
Result so far: 135930.0
Subtract 0 from 239 to get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Advancing to step 9:
The number 531 fits into 2390 4 times, leaving a remainder of 266.
Put 4 as the next digit of the answer. 
Result so far: 135930.4
The remainder is 266 after subtracting 2124 from 2390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 10:
531 goes into 2660 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 135930.45
Subtract 2655 from 2660 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
531 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 135930.45
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 12:
The number 531 fits into 500 0 times, leaving a remainder of 500.
The next digit of our result is 0. 
Result so far: 135930.45
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

After the division, we end up with 135930.45 and a remainder of 0.005.
