709103 ÷ 31 
The aim is to understand the frequency of 31 in 709103.

On to step 1:
7 divided by 31 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 31

Moving on to step 2:
The number 31 fits into 70 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 8 after subtracting 62 from 70.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 31

Let's proceed to step 3:
The number 31 fits into 89 2 times, leaving a remainder of 27.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Deduct 62 from 89 and we're left with 27.
Append the next digit (1) from the dividend to 27 and continue with: 271 / 31

Going ahead to step 4:
271 divided by 31 is 8 with a remainder of 23.
The next digit of our result is 8. 
Result so far: 228.0
Deduct 248 from 271 and we're left with 23.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 31

On to step 5:
31 can be fit into 230 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 2287.0
Deduct 217 from 230 and we're left with 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 31

Moving on to step 6:
The number 31 fits into 133 4 times, leaving a remainder of 9.
The next digit of our result is 4. 
Result so far: 22874.0
Subtract 124 from 133 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
31 goes into 90 2 times with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 22874.2
If we subtract 62 from 90, 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.

Let's proceed to step 8:
280 divided by 31 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 22874.29
Deduct 279 from 280 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
31 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 22874.29
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.

Moving on to step 10:
If we divide 100 by 31, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 22874.2903
Deduct 93 from 100 and we're left 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.

On to step 11:
When dividing 70 by 31, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 22874.29032
Subtract 62 from 70 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
If we divide 80 by 31, we get 2 and a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 22874.290322
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 final outcome is 22874.290322, with a leftover of 1.8e-06.
