37366 divided by 15 
The aim is to understand the frequency of 15 in 37366.

Moving on to step 1:
The number 15 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 15

Advancing to step 2:
The number 15 fits into 37 2 times, leaving a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 30 away from 37, we end up with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 15

On to step 3:
15 can be fit into 73 4 times, resulting in a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtract 60 from 73 to get 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 15

Going ahead to step 4:
If we divide 136 by 15, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 249.0
Subtract 135 from 136 to get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 15

Let's proceed to step 5:
The number 15 fits into 16 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 2491.0
Subtracting 15 from 16 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 6:
The number 15 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 2491.0
Subtracting 0 from 10 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.

On to step 7:
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: 2491.06
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 8:
If we divide 100 by 15, we get 6 and a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 2491.066
Deduct 90 from 100 and we're left 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 2491.066 with a remainder of 0.001.
