333422 divided by 15 
The aim is to understand the frequency of 15 in 333422.

Step 1:
If we divide 3 by 15, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 15

Moving on to step 2:
33 divided by 15 is 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 30 from 33 to get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 15

Step 3:
33 divided by 15 is 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Subtract 30 from 33 to get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 15

Advancing to step 4:
The number 15 fits into 34 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 222.0
Subtracting 30 from 34 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 15

Moving on to step 5:
The number 15 fits into 42 2 times, leaving a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 2222.0
If we take 30 away from 42, we end up with 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 15

Step 6:
The number 15 fits into 122 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 22228.0
Subtract 120 from 122 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.

Moving on to step 7:
15 goes into 20 1 times with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 22228.1
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.

Going ahead to step 8:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 22228.13
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.

On to step 9:
50 divided by 15 is 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 22228.133
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.

The final result is 22228.133 with a remainder of 0.0005.
