We divide 669166 by 15
The aim is to understand the frequency of 15 in 669166.

Step 1:
15 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 15

Let's proceed to step 2:
If we divide 66 by 15, we get 4 and a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 60 from 66 and we're left with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 15

On to step 3:
If we divide 69 by 15, we get 4 and a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 44.0
If we subtract 60 from 69, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 15

Moving on to step 4:
91 divided by 15 is 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 446.0
Deduct 90 from 91 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 15

Let's proceed to step 5:
If we divide 16 by 15, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 4461.0
The remainder is 1 after subtracting 15 from 16.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 15

Advancing to step 6:
The number 15 fits into 16 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 44611.0
Subtracting 15 from 16 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
The number 15 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 44611.0
If we subtract 0 from 10, 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.

Moving on to step 8:
The number 15 fits into 100 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 44611.06
Subtract 90 from 100 to 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.

Step 9:
100 divided by 15 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 44611.066
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.

After the division, we end up with 44611.066 and a remainder of 0.001.
