479927 divided by 15 
The aim is to understand the frequency of 15 in 479927.

Moving on to step 1:
When dividing 4 by 15, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 15

Step 2:
15 can be fit into 47 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 45 from 47, we get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 15

On to step 3:
When dividing 29 by 15, we get 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we subtract 15 from 29, we get 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 15

Going ahead to step 4:
15 goes into 149 9 times with a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 319.0
Deduct 135 from 149 and we're left with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 15

Step 5:
The number 15 fits into 142 9 times, leaving a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 3199.0
Subtract 135 from 142 to get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 15

Going ahead to step 6:
The number 15 fits into 77 5 times, leaving a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 31995.0
If we take 75 away from 77, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
20 divided by 15 is 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 31995.1
If we subtract 15 from 20, we 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.

Moving on to step 8:
If we divide 50 by 15, we get 3 and a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 31995.13
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.

Moving on to step 9:
15 goes into 50 3 times with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 31995.133
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 31995.133 with a remaining 0.0005.
