Let's divide 862481 by 15
The aim is to understand the frequency of 15 in 862481.

Advancing to step 1:
The number 15 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 15

Going ahead to step 2:
15 goes into 86 5 times with a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 75 from 86 leaves us with 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 15

On to step 3:
The number 15 fits into 112 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 57.0
Subtracting 105 from 112 leaves us with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 15

Let's proceed to step 4:
If we divide 74 by 15, we get 4 and a remainder of 14.
The next digit of our result is 4. 
Result so far: 574.0
If we subtract 60 from 74, we get 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 15

Let's proceed to step 5:
148 divided by 15 is 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 5749.0
If we take 135 away from 148, we end up with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 15

On to step 6:
The number 15 fits into 131 8 times, leaving a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 57498.0
Deduct 120 from 131 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
When dividing 110 by 15, we get 7 with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 57498.7
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
50 divided by 15 is 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 57498.73
Subtract 45 from 50 to 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.

Step 9:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 57498.733
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.

After the division, we end up with 57498.733 and a remainder of 0.0005.
