279470 ÷ 15 
The aim is to understand the frequency of 15 in 279470.

Moving on to step 1:
If we divide 2 by 15, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 15

On to step 2:
When dividing 27 by 15, we get 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 15 from 27, we get 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 15

On to step 3:
If we divide 129 by 15, we get 8 and a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 120 from 129 and we're left with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 15

Going ahead to step 4:
94 divided by 15 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 186.0
Subtracting 90 from 94 leaves us with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 15

Moving on to step 5:
47 divided by 15 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 1863.0
Deduct 45 from 47 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 15

Moving on to step 6:
The number 15 fits into 20 1 times, leaving a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 18631.0
If we take 15 away from 20, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
15 can be fit into 50 3 times, resulting in a remainder of 5.
The next digit of our result is 3. 
Result so far: 18631.3
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
The next digit of our result is 3. 
Result so far: 18631.33
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 18631.33, and the remainder is 0.005.
