884056 ÷ 15 
The aim is to understand the frequency of 15 in 884056.

Going ahead to step 1:
The number 15 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 15

Let's proceed to step 2:
15 goes into 88 5 times with a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 75 from 88 to get 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 15

On to step 3:
15 can be fit into 134 8 times, resulting in a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 58.0
The remainder is 14 after subtracting 120 from 134.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 15

On to step 4:
140 divided by 15 is 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 589.0
Deduct 135 from 140 and we're left with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 15

Advancing to step 5:
55 divided by 15 is 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 5893.0
If we subtract 45 from 55, we get 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 15

Going ahead to step 6:
15 can be fit into 106 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 58937.0
If we subtract 105 from 106, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
15 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 58937.0
Subtracting 0 from 10 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.

Advancing to step 8:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 58937.06
If we take 90 away from 100, we end up 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.

Let's proceed to step 9:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 58937.066
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.

The final result is 58937.066 with a remainder of 0.001.
