Let's divide 854030 by 15
The aim is to understand the frequency of 15 in 854030.

Step 1:
8 divided by 15 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 15

Moving on to step 2:
When dividing 85 by 15, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 75 from 85, we get 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 15

Step 3:
15 goes into 104 6 times with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
If we take 90 away from 104, we end up with 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 15

Let's proceed to step 4:
If we divide 140 by 15, we get 9 and a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 569.0
Deduct 135 from 140 and we're left with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 15

Advancing to step 5:
The number 15 fits into 53 3 times, leaving a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 5693.0
If we subtract 45 from 53, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 15

Going ahead to step 6:
15 can be fit into 80 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 56935.0
If we subtract 75 from 80, 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:
50 divided by 15 is 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 56935.3
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.

Advancing 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: 56935.33
If we subtract 45 from 50, 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.

The quotient of the division is 56935.33, and the remainder is 0.005.
