Let's divide 16303 by 31
The aim is to understand the frequency of 31 in 16303.

Going ahead to step 1:
When dividing 1 by 31, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 31

Let's proceed to step 2:
31 goes into 16 0 times with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 31

Advancing to step 3:
31 can be fit into 163 5 times, resulting in a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 8 after subtracting 155 from 163.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 31

Going ahead to step 4:
80 divided by 31 is 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 52.0
If we subtract 62 from 80, we get 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 31

Advancing to step 5:
31 goes into 183 5 times with a remainder of 28.
Record the quotient 5 as the next digit in the result. 
Result so far: 525.0
If we subtract 155 from 183, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 6:
280 divided by 31 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 525.9
The remainder is 1 after subtracting 279 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
If we divide 10 by 31, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 525.9
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
31 goes into 100 3 times with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 525.903
Subtracting 93 from 100 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
31 goes into 70 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 525.9032
Deduct 62 from 70 and we're left 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.

Going ahead to step 10:
31 can be fit into 80 2 times, resulting in a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 525.90322
The remainder is 18 after subtracting 62 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 525.90322 with a balance of 1.8e-05.
