We divide 728063 by 31
The aim is to understand the frequency of 31 in 728063.

Step 1:
7 divided by 31 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 31

Let's proceed to step 2:
31 goes into 72 2 times with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 62 from 72 leaves us with 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 31

Going ahead to step 3:
The number 31 fits into 108 3 times, leaving a remainder of 15.
The next digit of our result is 3. 
Result so far: 23.0
Subtracting 93 from 108 leaves us with 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 31

Let's proceed to step 4:
When dividing 150 by 31, we get 4 with a remainder of 26.
The next digit of our result is 4. 
Result so far: 234.0
If we take 124 away from 150, we end up with 26.
Grab the next digit (6) from the dividend, add it to 26, then carry on: 266 / 31

On to step 5:
266 divided by 31 is 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 2348.0
Subtract 248 from 266 to get 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 31

On to step 6:
If we divide 183 by 31, we get 5 and a remainder of 28.
Record the quotient 5 as the next digit in the result. 
Result so far: 23485.0
The remainder is 28 after subtracting 155 from 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 7:
280 divided by 31 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 23485.9
If we subtract 279 from 280, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
If we divide 10 by 31, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 23485.9
Subtracting 0 from 10 leaves us 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.

On to step 9:
The number 31 fits into 100 3 times, leaving a remainder of 7.
The next digit of our result is 3. 
Result so far: 23485.903
The remainder is 7 after subtracting 93 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 10:
If we divide 70 by 31, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 23485.9032
Subtracting 62 from 70 leaves us 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 11:
31 can be fit into 80 2 times, resulting in a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 23485.90322
Subtract 62 from 80 to get 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 quotient of the division is 23485.90322, and the remainder is 1.8e-05.
