234637 ÷ 15 
The aim is to understand the frequency of 15 in 234637.

Moving on to step 1:
When dividing 2 by 15, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 15

Moving on to step 2:
23 divided by 15 is 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 15 away from 23, we end up with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 15

On to step 3:
When dividing 84 by 15, we get 5 with a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 75 from 84 and we're left with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 15

Let's proceed to step 4:
When dividing 96 by 15, we get 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 156.0
If we take 90 away from 96, we end up with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 15

Step 5:
If we divide 63 by 15, we get 4 and a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 1564.0
Subtract 60 from 63 to get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 15

Advancing to step 6:
15 goes into 37 2 times with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 15642.0
Subtracting 30 from 37 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
The number 15 fits into 70 4 times, leaving a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 15642.4
If we take 60 away from 70, 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.

Let's proceed to step 8:
When dividing 100 by 15, we get 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 15642.46
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.

Going ahead to step 9:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 15642.466
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 final outcome is 15642.466, with a leftover of 0.001.
