We divide 999264 by 15
The aim is to understand the frequency of 15 in 999264.

Step 1:
15 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 15

Let's proceed to step 2:
If we divide 99 by 15, we get 6 and a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 9 after subtracting 90 from 99.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 15

Advancing to step 3:
99 divided by 15 is 6 with a remainder of 9.
The next digit of our result is 6. 
Result so far: 66.0
Subtract 90 from 99 to get 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 15

Advancing to step 4:
The number 15 fits into 92 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 666.0
The remainder is 2 after subtracting 90 from 92.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 15

Advancing to step 5:
The number 15 fits into 26 1 times, leaving a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 6661.0
Subtract 15 from 26 to get 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 15

Step 6:
114 divided by 15 is 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 66617.0
Deduct 105 from 114 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
90 divided by 15 is 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 66617.6
If we subtract 90 from 90, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
When dividing 0 by 15, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 66617.6
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
15 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 66617.6
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 66617.6, and the remainder is 0.0.
