We divide 455755 by 15
The aim is to understand the frequency of 15 in 455755.

Advancing to step 1:
15 goes into 4 0 times with 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.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 15

On to step 2:
The number 15 fits into 45 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 45 away from 45, we end up with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 15

Let's proceed to step 3:
15 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Subtract 0 from 5 to get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 15

Advancing to step 4:
15 goes into 57 3 times with a remainder of 12.
The next digit of our result is 3. 
Result so far: 303.0
Deduct 45 from 57 and we're left with 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 15

Let's proceed to step 5:
The number 15 fits into 125 8 times, leaving a remainder of 5.
The next digit of our result is 8. 
Result so far: 3038.0
Subtracting 120 from 125 leaves us with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 15

On to step 6:
15 can be fit into 55 3 times, resulting in a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 30383.0
Deduct 45 from 55 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
15 goes into 100 6 times with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 30383.6
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
100 divided by 15 is 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 30383.66
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 30383.66, with a leftover of 0.01.
