We're dividing 473657 by 15 
The aim is to understand the frequency of 15 in 473657.

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
If we take 0 away from 4, we end up with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 15

Step 2:
When dividing 47 by 15, we get 3 with 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.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 15

On to step 3:
15 can be fit into 23 1 times, resulting in a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Deduct 15 from 23 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 15

Step 4:
The number 15 fits into 86 5 times, leaving a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 315.0
Subtract 75 from 86 to get 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 15

Moving on to step 5:
The number 15 fits into 115 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 3157.0
If we take 105 away from 115, we end up with 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 15

Going ahead to step 6:
The number 15 fits into 107 7 times, leaving a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 31577.0
Subtract 105 from 107 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
The number 15 fits into 20 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 31577.1
Subtract 15 from 20 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 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 31577.13
If we take 45 away from 50, we end up 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.

Going ahead to step 9:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 31577.133
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.

The final outcome is 31577.133, with a leftover of 0.0005.
