We look at the division of 474664 by 15 
The aim is to understand the frequency of 15 in 474664.

Moving on to step 1:
15 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 15

Step 2:
If we divide 47 by 15, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 45 from 47 to get 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 15

Step 3:
15 goes into 24 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Deduct 15 from 24 and we're left with 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 15

On to step 4:
When dividing 96 by 15, we get 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 316.0
Deduct 90 from 96 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 15

Step 5:
When dividing 66 by 15, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 3164.0
Subtract 60 from 66 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 15

Moving on to step 6:
The number 15 fits into 64 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 31644.0
If we subtract 60 from 64, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
15 goes into 40 2 times with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 31644.2
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.
Write down 6 as next digit of the result. 
Result so far: 31644.26
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.

Moving on to step 9:
15 goes into 100 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 31644.266
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.

The quotient of the division is 31644.266, and the remainder is 0.001.
