We're dividing 432450 by 31 
The aim is to understand the frequency of 31 in 432450.

Step 1:
4 divided by 31 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 31

Moving on to step 2:
31 goes into 43 1 times with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 31 away from 43, we end up with 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 31

Step 3:
122 divided by 31 is 3 with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 93 from 122 to get 29.
Include the next digit (4) from the dividend after 29, then repeat: 294 / 31

Advancing to step 4:
31 goes into 294 9 times with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 139.0
If we subtract 279 from 294, we get 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 31

Moving on to step 5:
The number 31 fits into 155 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1395.0
If we subtract 155 from 155, we get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 31

Let's proceed to step 6:
If we divide 0 by 31, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13950.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
When dividing 0 by 31, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 13950.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
If we divide 0 by 31, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13950.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 13950.0 with a remainder of 0.0.
