Let's divide 71386205 by 531
The aim is to understand the frequency of 531 in 71386205.

Step 1:
531 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 531

Advancing to step 2:
When dividing 71 by 531, we get 0 with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Include the next digit (3) from the dividend after 71, then repeat: 713 / 531

Advancing to step 3:
If we divide 713 by 531, we get 1 and a remainder of 182.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 531 from 713 leaves us with 182.
Fetch the next digit (8) from the dividend, attach it to 182 and continue: 1828 / 531

Let's proceed to step 4:
1828 divided by 531 is 3 with a remainder of 235.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 1593 from 1828 to get 235.
Bring next digit (6) of the dividend behind the 235 and repeat the process: 2356 / 531

Let's proceed to step 5:
The number 531 fits into 2356 4 times, leaving a remainder of 232.
The number 4 becomes the next digit in our result. 
Result so far: 134.0
Subtract 2124 from 2356 to get 232.
Include the next digit (2) from the dividend after 232, then repeat: 2322 / 531

Going ahead to step 6:
2322 divided by 531 is 4 with a remainder of 198.
The next digit of our result is 4. 
Result so far: 1344.0
The remainder is 198 after subtracting 2124 from 2322.
Append the next digit (0) from the dividend to 198 and continue with: 1980 / 531

Moving on to step 7:
1980 divided by 531 is 3 with a remainder of 387.
The number 3 becomes the next digit in our result. 
Result so far: 13443.0
Subtracting 1593 from 1980 leaves us with 387.
Grab the next digit (5) from the dividend, add it to 387, then carry on: 3875 / 531

Going ahead to step 8:
When dividing 3875 by 531, we get 7 with a remainder of 158.
The number 7 becomes the next digit in our result. 
Result so far: 134437.0
If we take 3717 away from 3875, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 9:
If we divide 1580 by 531, we get 2 and a remainder of 518.
Use 2 as the next digit of our solution. 
Result so far: 134437.2
The remainder is 518 after subtracting 1062 from 1580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Going ahead to step 10:
If we divide 5180 by 531, we get 9 and a remainder of 401.
Put 9 as the next digit of the answer. 
Result so far: 134437.29
Subtracting 4779 from 5180 leaves us with 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

On to step 11:
If we divide 4010 by 531, we get 7 and a remainder of 293.
The number 7 becomes the next digit in our result. 
Result so far: 134437.297
Subtracting 3717 from 4010 leaves us with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Let's proceed to step 12:
When dividing 2930 by 531, we get 5 with a remainder of 275.
Record the quotient 5 as the next digit in the result. 
Result so far: 134437.2975
If we take 2655 away from 2930, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 13:
531 goes into 2750 5 times with a remainder of 95.
The next digit of our result is 5. 
Result so far: 134437.29755
Subtracting 2655 from 2750 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

The final result is 134437.29755 with a remainder of 9.5e-05.
