We divide 38116370 by 15
The aim is to understand the frequency of 15 in 38116370.

Moving on to step 1:
If we divide 3 by 15, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 15

On to step 2:
15 can be fit into 38 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 30 from 38 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 15

Advancing to step 3:
The number 15 fits into 81 5 times, leaving a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
The remainder is 6 after subtracting 75 from 81.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 15

Going ahead to step 4:
The number 15 fits into 61 4 times, leaving a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 254.0
If we subtract 60 from 61, we get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 15

On to step 5:
When dividing 16 by 15, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 2541.0
Deduct 15 from 16 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 15

Moving on to step 6:
15 goes into 13 0 times with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 25410.0
Deduct 0 from 13 and we're left with 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 15

Step 7:
15 can be fit into 137 9 times, resulting in a remainder of 2.
The next digit of our result is 9. 
Result so far: 254109.0
Subtract 135 from 137 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 15

Step 8:
The number 15 fits into 20 1 times, leaving a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 2541091.0
Subtracting 15 from 20 leaves us 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:
50 divided by 15 is 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 2541091.3
The remainder is 5 after subtracting 45 from 50.
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 10:
50 divided by 15 is 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 2541091.33
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 2541091.33, with a leftover of 0.005.
