We're dividing 442670 by 15 
The aim is to understand the frequency of 15 in 442670.

Moving on to step 1:
The number 15 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 15

On to step 2:
15 goes into 44 2 times with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 30 away from 44, we end up with 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 15

Advancing to step 3:
15 goes into 142 9 times with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we take 135 away from 142, we end up with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 15

Step 4:
15 goes into 76 5 times with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 295.0
Subtract 75 from 76 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 15

On to step 5:
The number 15 fits into 17 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 2951.0
If we take 15 away from 17, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 15

Step 6:
15 goes into 20 1 times with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 29511.0
If we subtract 15 from 20, we get 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 7:
If we divide 50 by 15, we get 3 and a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 29511.3
The remainder is 5 after subtracting 45 from 50.
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 8:
15 goes into 50 3 times with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 29511.33
If we take 45 away from 50, 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.

After the division, we end up with 29511.33 and a remainder of 0.005.
