We divide 395477 by 15
The aim is to understand the frequency of 15 in 395477.

On to step 1:
15 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 15

Going ahead to step 2:
If we divide 39 by 15, we get 2 and a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 30 from 39 and we're left with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 15

Advancing to step 3:
15 can be fit into 95 6 times, resulting in a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Deduct 90 from 95 and we're left with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 15

Step 4:
If we divide 54 by 15, we get 3 and a remainder of 9.
The next digit of our result is 3. 
Result so far: 263.0
If we subtract 45 from 54, we get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 15

Step 5:
If we divide 97 by 15, we get 6 and a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 2636.0
Subtracting 90 from 97 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 15

Advancing to step 6:
15 goes into 77 5 times with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 26365.0
Subtract 75 from 77 to get 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:
20 divided by 15 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 26365.1
If we take 15 away from 20, we end up 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.

Advancing to step 8:
50 divided by 15 is 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 26365.13
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.

Let's proceed to step 9:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 26365.133
Deduct 45 from 50 and we're left 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.

After the division, we end up with 26365.133 and a remainder of 0.0005.
