We divide 714975 by 31
The aim is to understand the frequency of 31 in 714975.

Step 1:
31 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 31

Advancing to step 2:
71 divided by 31 is 2 with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 62 from 71, we get 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 31

Moving on to step 3:
94 divided by 31 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtracting 93 from 94 leaves us with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 31

On to step 4:
19 divided by 31 is 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 230.0
If we take 0 away from 19, we end up with 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 31

Going ahead to step 5:
If we divide 197 by 31, we get 6 and a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 2306.0
Subtract 186 from 197 to get 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 31

Step 6:
The number 31 fits into 115 3 times, leaving a remainder of 22.
The next digit of our result is 3. 
Result so far: 23063.0
Subtracting 93 from 115 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
When dividing 220 by 31, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 23063.7
Deduct 217 from 220 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
30 divided by 31 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 23063.7
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
If we divide 300 by 31, we get 9 and a remainder of 21.
The next digit of our result is 9. 
Result so far: 23063.709
If we subtract 279 from 300, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 10:
When dividing 210 by 31, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 23063.7096
Deduct 186 from 210 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
240 divided by 31 is 7 with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 23063.70967
If we subtract 217 from 240, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 12:
31 can be fit into 230 7 times, resulting in a remainder of 13.
The next digit of our result is 7. 
Result so far: 23063.709677
The remainder is 13 after subtracting 217 from 230.
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 23063.709677 with a remainder of 1.3e-06.
