We're dividing 613336 by 15 
The aim is to understand the frequency of 15 in 613336.

On to step 1:
If we divide 6 by 15, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 15

Let's proceed to step 2:
The number 15 fits into 61 4 times, leaving a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 60 from 61 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 15

Let's proceed to step 3:
If we divide 13 by 15, we get 0 and a remainder of 13.
The next digit of our result is 0. 
Result so far: 40.0
Subtract 0 from 13 to get 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 15

On to step 4:
If we divide 133 by 15, we get 8 and a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 408.0
Subtracting 120 from 133 leaves us with 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 15

Going ahead to step 5:
133 divided by 15 is 8 with a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 4088.0
Subtract 120 from 133 to get 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 15

Going ahead to step 6:
The number 15 fits into 136 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 40889.0
The remainder is 1 after subtracting 135 from 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
The number 15 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 40889.0
If we subtract 0 from 10, we get 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:
15 goes into 100 6 times with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 40889.06
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 9:
100 divided by 15 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 40889.066
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 40889.066, and the remainder is 0.001.
