We're dividing 73074 by 31 
The aim is to understand the frequency of 31 in 73074.

Let's proceed to step 1:
When dividing 7 by 31, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 31

Step 2:
When dividing 73 by 31, we get 2 with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 62 from 73 leaves us with 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 31

On to step 3:
110 divided by 31 is 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we subtract 93 from 110, we get 17.
Include the next digit (7) from the dividend after 17, then repeat: 177 / 31

Moving on to step 4:
If we divide 177 by 31, we get 5 and a remainder of 22.
The number 5 becomes the next digit in our result. 
Result so far: 235.0
If we take 155 away from 177, we end up with 22.
Fetch the next digit (4) from the dividend, attach it to 22 and continue: 224 / 31

Let's proceed to step 5:
31 can be fit into 224 7 times, resulting in a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 2357.0
The remainder is 7 after subtracting 217 from 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 6:
The number 31 fits into 70 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2357.2
If we take 62 away from 70, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
If we divide 80 by 31, we get 2 and a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 2357.22
If we take 62 away from 80, we end up with 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 2357.22 with a remainder of 0.018.
