We divide 336358 by 15
The aim is to understand the frequency of 15 in 336358.

Let's proceed to step 1:
When dividing 3 by 15, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 15

Advancing to step 2:
If we divide 33 by 15, we get 2 and a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 30 from 33, we get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 15

On to step 3:
If we divide 36 by 15, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtracting 30 from 36 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 15

On to step 4:
When dividing 63 by 15, we get 4 with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 224.0
If we take 60 away from 63, we end up with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 15

Let's proceed to step 5:
If we divide 35 by 15, we get 2 and a remainder of 5.
The next digit of our result is 2. 
Result so far: 2242.0
If we take 30 away from 35, we end up with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 15

Advancing to step 6:
15 can be fit into 58 3 times, resulting in a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 22423.0
Subtract 45 from 58 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
15 goes into 130 8 times with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 22423.8
The remainder is 10 after subtracting 120 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 15 is 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 22423.86
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.

Moving on to step 9:
100 divided by 15 is 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 22423.866
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.

After the division, we end up with 22423.866 and a remainder of 0.001.
