We divide 489441 by 15
The aim is to understand the frequency of 15 in 489441.

Advancing to step 1:
If we divide 4 by 15, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 15

Let's proceed to step 2:
If we divide 48 by 15, we get 3 and a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 45 from 48 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 15

Let's proceed to step 3:
15 can be fit into 39 2 times, resulting in a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Subtracting 30 from 39 leaves us with 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 15

Step 4:
94 divided by 15 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 326.0
Subtract 90 from 94 to get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 15

Step 5:
The number 15 fits into 44 2 times, leaving a remainder of 14.
The next digit of our result is 2. 
Result so far: 3262.0
Subtracting 30 from 44 leaves us with 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 15

Moving on to step 6:
141 divided by 15 is 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 32629.0
If we subtract 135 from 141, we 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:
60 divided by 15 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 32629.4
If we take 60 away from 60, 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.

On to step 8:
When dividing 0 by 15, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 32629.4
Subtracting 0 from 0 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 9:
If we divide 0 by 15, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 32629.4
If we subtract 0 from 0, we 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.

The final result is 32629.4 with a remainder of 0.0.
