293601 divided by 15 
The aim is to understand the frequency of 15 in 293601.

Going ahead to step 1:
2 divided by 15 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 15

Step 2:
15 goes into 29 1 times with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 15 from 29 leaves us with 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 15

Moving on to step 3:
When dividing 143 by 15, we get 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we take 135 away from 143, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 15

Let's proceed to step 4:
86 divided by 15 is 5 with a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 195.0
If we take 75 away from 86, we end up with 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 15

Moving on to step 5:
The number 15 fits into 110 7 times, leaving a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 1957.0
If we subtract 105 from 110, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 15

Moving on to step 6:
If we divide 51 by 15, we get 3 and a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 19573.0
Subtract 45 from 51 to 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.

Moving on to step 7:
The number 15 fits into 60 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 19573.4
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:
15 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 19573.4
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.

Going ahead to step 9:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 19573.4
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.

The quotient of the division is 19573.4, and the remainder is 0.0.
