We divide 237100 by 15
The aim is to understand the frequency of 15 in 237100.

Going ahead to step 1:
2 divided by 15 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
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

Advancing to step 2:
If we divide 23 by 15, we get 1 and a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 8 after subtracting 15 from 23.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 15

Step 3:
If we divide 87 by 15, we get 5 and a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 75 from 87, we get 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 15

On to step 4:
15 can be fit into 121 8 times, resulting in a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 158.0
If we take 120 away from 121, we end up with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 15

Step 5:
15 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1580.0
The remainder is 10 after subtracting 0 from 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 15

On to step 6:
If we divide 100 by 15, we get 6 and a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 15806.0
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.

On to step 7:
15 goes into 100 6 times with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 15806.6
The remainder is 10 after subtracting 90 from 100.
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 8:
When dividing 100 by 15, we get 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 15806.66
Subtracting 90 from 100 leaves us 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 result is 15806.66 with a remainder of 0.01.
