18782323 divided by 531 
The aim is to understand the frequency of 531 in 18782323.

Going ahead to step 1:
1 divided by 531 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 531

Advancing to step 2:
531 goes into 18 0 times with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 531

Step 3:
531 goes into 187 0 times with a remainder of 187.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 187 after subtracting 0 from 187.
Include the next digit (8) from the dividend after 187, then repeat: 1878 / 531

Step 4:
The number 531 fits into 1878 3 times, leaving a remainder of 285.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 1593 away from 1878, we end up with 285.
Include the next digit (2) from the dividend after 285, then repeat: 2852 / 531

Moving on to step 5:
531 goes into 2852 5 times with a remainder of 197.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Subtract 2655 from 2852 to get 197.
Include the next digit (3) from the dividend after 197, then repeat: 1973 / 531

Advancing to step 6:
531 goes into 1973 3 times with a remainder of 380.
The number 3 becomes the next digit in our result. 
Result so far: 353.0
Subtracting 1593 from 1973 leaves us with 380.
Fetch the next digit (2) from the dividend, attach it to 380 and continue: 3802 / 531

Going ahead to step 7:
531 can be fit into 3802 7 times, resulting in a remainder of 85.
The number 7 becomes the next digit in our result. 
Result so far: 3537.0
Subtract 3717 from 3802 to get 85.
Append the next digit (3) from the dividend to 85 and continue with: 853 / 531

On to step 8:
531 can be fit into 853 1 times, resulting in a remainder of 322.
Use 1 as the next digit of our solution. 
Result so far: 35371.0
Subtracting 531 from 853 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 9:
3220 divided by 531 is 6 with a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 35371.6
If we subtract 3186 from 3220, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
When dividing 340 by 531, we get 0 with a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 35371.6
If we take 0 away from 340, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 11:
The number 531 fits into 3400 6 times, leaving a remainder of 214.
The number 6 becomes the next digit in our result. 
Result so far: 35371.606
If we subtract 3186 from 3400, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 12:
2140 divided by 531 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 35371.6064
Subtract 2124 from 2140 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.

On to step 13:
When dividing 160 by 531, we get 0 with a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 35371.6064
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 14:
When dividing 1600 by 531, we get 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 35371.606403
The remainder is 7 after subtracting 1593 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 15:
If we divide 70 by 531, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 35371.606403
If we take 0 away from 70, 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.

Let's proceed to step 16:
531 goes into 700 1 times with a remainder of 169.
Use 1 as the next digit of our solution. 
Result so far: 35371.60640301
Subtracting 531 from 700 leaves us with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Our division results in 35371.60640301 with a remaining 1.69e-07.
