298343 ÷ 15 
The aim is to understand the frequency of 15 in 298343.

Moving on to step 1:
When dividing 2 by 15, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 15

Moving on to step 2:
15 can be fit into 29 1 times, resulting in a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
If we take 15 away from 29, we end up with 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 15

Going ahead to step 3:
15 goes into 148 9 times with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we subtract 135 from 148, we get 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 15

Moving on to step 4:
If we divide 133 by 15, we get 8 and a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 198.0
Subtracting 120 from 133 leaves us with 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 15

Let's proceed to step 5:
The number 15 fits into 134 8 times, leaving a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 1988.0
The remainder is 14 after subtracting 120 from 134.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 15

Going ahead to step 6:
When dividing 143 by 15, we get 9 with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 19889.0
If we take 135 away from 143, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
15 can be fit into 80 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 19889.5
Subtracting 75 from 80 leaves us 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 8:
If we divide 50 by 15, we get 3 and a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 19889.53
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 19889.533
Subtracting 45 from 50 leaves us 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 19889.533, and the remainder is 0.0005.
