72896349 ÷ 531 
The aim is to understand the frequency of 531 in 72896349.

Going ahead to step 1:
The number 531 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 531

Let's proceed to step 2:
531 goes into 72 0 times with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Grab the next digit (8) from the dividend, add it to 72, then carry on: 728 / 531

Moving on to step 3:
728 divided by 531 is 1 with a remainder of 197.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 531 from 728 and we're left with 197.
Bring next digit (9) of the dividend behind the 197 and repeat the process: 1979 / 531

Step 4:
The number 531 fits into 1979 3 times, leaving a remainder of 386.
The next digit of our result is 3. 
Result so far: 13.0
If we take 1593 away from 1979, we end up with 386.
Bring next digit (6) of the dividend behind the 386 and repeat the process: 3866 / 531

Advancing to step 5:
531 goes into 3866 7 times with a remainder of 149.
The number 7 becomes the next digit in our result. 
Result so far: 137.0
Subtracting 3717 from 3866 leaves us with 149.
Append the next digit (3) from the dividend to 149 and continue with: 1493 / 531

Step 6:
1493 divided by 531 is 2 with a remainder of 431.
The next digit of our result is 2. 
Result so far: 1372.0
If we subtract 1062 from 1493, we get 431.
Take the next digit (4) from the dividend and append it to 431, then repeat: 4314 / 531

Going ahead to step 7:
4314 divided by 531 is 8 with a remainder of 66.
The next digit of our result is 8. 
Result so far: 13728.0
If we take 4248 away from 4314, we end up with 66.
Include the next digit (9) from the dividend after 66, then repeat: 669 / 531

Going ahead to step 8:
531 can be fit into 669 1 times, resulting in a remainder of 138.
Use 1 as the next digit of our solution. 
Result so far: 137281.0
If we take 531 away from 669, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 9:
531 goes into 1380 2 times with a remainder of 318.
Put 2 as the next digit of the answer. 
Result so far: 137281.2
If we take 1062 away from 1380, we end up with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Advancing to step 10:
3180 divided by 531 is 5 with a remainder of 525.
Put 5 as the next digit of the answer. 
Result so far: 137281.25
Subtract 2655 from 3180 to get 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Step 11:
531 can be fit into 5250 9 times, resulting in a remainder of 471.
Write down 9 as next digit of the result. 
Result so far: 137281.259
If we subtract 4779 from 5250, we get 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Moving on to step 12:
531 can be fit into 4710 8 times, resulting in a remainder of 462.
The number 8 becomes the next digit in our result. 
Result so far: 137281.2598
The remainder is 462 after subtracting 4248 from 4710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

On to step 13:
If we divide 4620 by 531, we get 8 and a remainder of 372.
The number 8 becomes the next digit in our result. 
Result so far: 137281.25988
If we subtract 4248 from 4620, we get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Our division results in 137281.25988 with a remaining 0.000372.
