We divide 539706 by 15
The aim is to understand the frequency of 15 in 539706.

On to step 1:
5 divided by 15 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 15

Going ahead to step 2:
When dividing 53 by 15, we get 3 with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 45 from 53 to get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 15

Let's proceed to step 3:
If we divide 89 by 15, we get 5 and a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 35.0
If we take 75 away from 89, we end up with 14.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 15

Let's proceed to step 4:
147 divided by 15 is 9 with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 359.0
If we take 135 away from 147, we end up with 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 15

Going ahead to step 5:
When dividing 120 by 15, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 3598.0
Subtracting 120 from 120 leaves us with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 15

Going ahead to step 6:
6 divided by 15 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 35980.0
If we subtract 0 from 6, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
15 can be fit into 60 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 35980.4
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
If we divide 0 by 15, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 35980.4
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.

On to step 9:
0 divided by 15 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 35980.4
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.

The quotient of the division is 35980.4, and the remainder is 0.0.
