Let's divide 575022 by 31
The aim is to understand the frequency of 31 in 575022.

On to step 1:
If we divide 5 by 31, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 31

Let's proceed to step 2:
31 can be fit into 57 1 times, resulting in a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 31 from 57 leaves us with 26.
Fetch the next digit (5) from the dividend, attach it to 26 and continue: 265 / 31

Moving on to step 3:
If we divide 265 by 31, we get 8 and a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtract 248 from 265 to get 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 31

On to step 4:
170 divided by 31 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 185.0
Subtract 155 from 170 to get 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 31

Let's proceed to step 5:
When dividing 152 by 31, we get 4 with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 1854.0
Subtracting 124 from 152 leaves us with 28.
Append the next digit (2) from the dividend to 28 and continue with: 282 / 31

Moving on to step 6:
When dividing 282 by 31, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 18549.0
If we subtract 279 from 282, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
When dividing 30 by 31, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 18549.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
When dividing 300 by 31, we get 9 with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 18549.09
If we take 279 away from 300, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
The number 31 fits into 210 6 times, leaving a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 18549.096
The remainder is 24 after subtracting 186 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
31 goes into 240 7 times with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 18549.0967
Subtracting 217 from 240 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 11:
31 goes into 230 7 times with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 18549.09677
If we subtract 217 from 230, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 18549.09677 with a remainder of 1.3e-05.
