We divide 389402 by 15
The aim is to understand the frequency of 15 in 389402.

Let's proceed to step 1:
15 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 15

Step 2:
When dividing 38 by 15, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 30 from 38 to get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 15

Let's proceed to step 3:
The number 15 fits into 89 5 times, leaving a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtract 75 from 89 to get 14.
Grab the next digit (4) from the dividend, add it to 14, then carry on: 144 / 15

Let's proceed to step 4:
When dividing 144 by 15, we get 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 259.0
Deduct 135 from 144 and we're left with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 15

Moving on to step 5:
The number 15 fits into 90 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 2596.0
Subtracting 90 from 90 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 15

On to step 6:
The number 15 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 25960.0
Deduct 0 from 2 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
If we divide 20 by 15, we get 1 and a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 25960.1
If we subtract 15 from 20, 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 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 25960.13
The remainder is 5 after subtracting 45 from 50.
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 9:
50 divided by 15 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 25960.133
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 25960.133, and the remainder is 0.0005.
