We divide 286341 by 15
The aim is to understand the frequency of 15 in 286341.

Moving on to step 1:
The number 15 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 15

On to step 2:
The number 15 fits into 28 1 times, leaving a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 15 from 28 to get 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 15

Step 3:
15 goes into 136 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 1 after subtracting 135 from 136.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 15

On to step 4:
The number 15 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 190.0
Deduct 0 from 13 and we're left with 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 15

Moving on to step 5:
15 goes into 134 8 times with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 1908.0
Subtracting 120 from 134 leaves us with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 15

Going ahead to step 6:
15 goes into 141 9 times with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 19089.0
If we take 135 away from 141, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
15 goes into 60 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 19089.4
Subtracting 60 from 60 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.

Let's proceed to step 8:
15 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 19089.4
Subtract 0 from 0 to 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.

Advancing to step 9:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 19089.4
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.

After the division, we end up with 19089.4 and a remainder of 0.0.
