We look at the division of 17497671 by 31 
The aim is to understand the frequency of 31 in 17497671.

Let's proceed to step 1:
1 divided by 31 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 31

Going ahead to step 2:
When dividing 17 by 31, we get 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Include the next digit (4) from the dividend after 17, then repeat: 174 / 31

Advancing to step 3:
When dividing 174 by 31, we get 5 with a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 155 from 174 and we're left with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 31

Step 4:
31 can be fit into 199 6 times, resulting in a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 56.0
If we take 186 away from 199, we end up with 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 31

Step 5:
31 goes into 137 4 times with a remainder of 13.
The next digit of our result is 4. 
Result so far: 564.0
Subtract 124 from 137 to get 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 31

Step 6:
When dividing 136 by 31, we get 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 5644.0
Deduct 124 from 136 and we're left with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 31

Let's proceed to step 7:
127 divided by 31 is 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 56444.0
Deduct 124 from 127 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 31

Let's proceed to step 8:
The number 31 fits into 31 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 564441.0
Deduct 31 from 31 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
The number 31 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 564441.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
If we divide 0 by 31, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 564441.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 564441.0 with a balance of 0.0.
