Let's divide 842914 by 15
The aim is to understand the frequency of 15 in 842914.

Step 1:
The number 15 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 15

On to step 2:
When dividing 84 by 15, we get 5 with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 75 from 84 leaves us with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 15

On to step 3:
If we divide 92 by 15, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 56.0
Subtracting 90 from 92 leaves us with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 15

Let's proceed to step 4:
15 can be fit into 29 1 times, resulting in a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 561.0
If we take 15 away from 29, we end up with 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 15

Advancing to step 5:
When dividing 141 by 15, we get 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 5619.0
Subtracting 135 from 141 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 15

Step 6:
The number 15 fits into 64 4 times, leaving a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 56194.0
Deduct 60 from 64 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
15 can be fit into 40 2 times, resulting in a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 56194.2
The remainder is 10 after subtracting 30 from 40.
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:
If we divide 100 by 15, we get 6 and a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 56194.26
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
If we divide 100 by 15, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 56194.266
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 56194.266 with a remaining 0.001.
