31871466 divided by 531 
The aim is to understand the frequency of 531 in 31871466.

Step 1:
When dividing 3 by 531, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 531

On to step 2:
The number 531 fits into 31 0 times, leaving a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Take the next digit (8) from the dividend and append it to 31, then repeat: 318 / 531

Going ahead to step 3:
318 divided by 531 is 0 with a remainder of 318.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 318, we end up with 318.
Append the next digit (7) from the dividend to 318 and continue with: 3187 / 531

Let's proceed to step 4:
531 can be fit into 3187 6 times, resulting in a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 3186 from 3187 and we're left with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 531

Moving on to step 5:
The number 531 fits into 11 0 times, leaving a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
If we take 0 away from 11, we end up with 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 531

Advancing to step 6:
531 goes into 114 0 times with a remainder of 114.
Put 0 as the next digit of the answer. 
Result so far: 600.0
The remainder is 114 after subtracting 0 from 114.
Grab the next digit (6) from the dividend, add it to 114, then carry on: 1146 / 531

Advancing to step 7:
531 goes into 1146 2 times with a remainder of 84.
The next digit of our result is 2. 
Result so far: 6002.0
If we subtract 1062 from 1146, we get 84.
Append the next digit (6) from the dividend to 84 and continue with: 846 / 531

On to step 8:
531 can be fit into 846 1 times, resulting in a remainder of 315.
Record the quotient 1 as the next digit in the result. 
Result so far: 60021.0
Subtract 531 from 846 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

On to step 9:
531 can be fit into 3150 5 times, resulting in a remainder of 495.
Use 5 as the next digit of our solution. 
Result so far: 60021.5
If we subtract 2655 from 3150, we get 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Step 10:
4950 divided by 531 is 9 with a remainder of 171.
Put 9 as the next digit of the answer. 
Result so far: 60021.59
The remainder is 171 after subtracting 4779 from 4950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Let's proceed to step 11:
When dividing 1710 by 531, we get 3 with a remainder of 117.
The next digit of our result is 3. 
Result so far: 60021.593
The remainder is 117 after subtracting 1593 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Advancing to step 12:
The number 531 fits into 1170 2 times, leaving a remainder of 108.
The next digit of our result is 2. 
Result so far: 60021.5932
Subtract 1062 from 1170 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 13:
531 goes into 1080 2 times with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 60021.59322
Subtract 1062 from 1080 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 60021.59322 with a remainder of 1.8e-05.
