We look at the division of 31167 by 15 
The aim is to understand the frequency of 15 in 31167.

Step 1:
3 divided by 15 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 15

Advancing to step 2:
15 can be fit into 31 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 30 from 31, we get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 15

Advancing to step 3:
The number 15 fits into 11 0 times, leaving a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Deduct 0 from 11 and we're left with 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 15

Let's proceed to step 4:
When dividing 116 by 15, we get 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 207.0
If we subtract 105 from 116, we get 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 15

On to step 5:
15 can be fit into 117 7 times, resulting in a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 2077.0
If we take 105 away from 117, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 6:
If we divide 120 by 15, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 2077.8
Deduct 120 from 120 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.

Going ahead to step 7:
0 divided by 15 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2077.8
If we take 0 away from 0, we end up 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.

Let's proceed to step 8:
0 divided by 15 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2077.8
Subtracting 0 from 0 leaves us 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.

The final result is 2077.8 with a remainder of 0.0.
