Let's divide 564592 by 15
The aim is to understand the frequency of 15 in 564592.

Moving on to step 1:
When dividing 5 by 15, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 15

Moving on to step 2:
15 goes into 56 3 times with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 45 away from 56, we end up with 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 15

Going ahead to step 3:
15 can be fit into 114 7 times, resulting in a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
If we subtract 105 from 114, we get 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 15

Moving on to step 4:
If we divide 95 by 15, we get 6 and a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 376.0
Subtracting 90 from 95 leaves us with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 15

Going ahead to step 5:
15 can be fit into 59 3 times, resulting in a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 3763.0
The remainder is 14 after subtracting 45 from 59.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 15

Moving on to step 6:
When dividing 142 by 15, we get 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 37639.0
Subtracting 135 from 142 leaves us 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.

Moving on to step 7:
If we divide 70 by 15, we get 4 and a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 37639.4
Subtracting 60 from 70 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.

Going ahead to step 8:
If we divide 100 by 15, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 37639.46
If we subtract 90 from 100, we get 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 9:
When dividing 100 by 15, we get 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 37639.466
Subtracting 90 from 100 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.

The final outcome is 37639.466, with a leftover of 0.001.
