652157 ÷ 15 
The aim is to understand the frequency of 15 in 652157.

On to step 1:
When dividing 6 by 15, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 15

Moving on to step 2:
The number 15 fits into 65 4 times, leaving a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 60 from 65 and we're left with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 15

Step 3:
15 can be fit into 52 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 43.0
The remainder is 7 after subtracting 45 from 52.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 15

Step 4:
15 goes into 71 4 times with a remainder of 11.
The next digit of our result is 4. 
Result so far: 434.0
The remainder is 11 after subtracting 60 from 71.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 15

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: 4347.0
The remainder is 10 after subtracting 105 from 115.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 15

Moving on to step 6:
15 can be fit into 107 7 times, resulting in a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 43477.0
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.

Step 7:
15 can be fit into 20 1 times, resulting in a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 43477.1
The remainder is 5 after subtracting 15 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 43477.13
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.

Advancing to step 9:
If we divide 50 by 15, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 43477.133
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.

After the division, we end up with 43477.133 and a remainder of 0.0005.
