22849529 divided by 15 
The aim is to understand the frequency of 15 in 22849529.

Advancing to step 1:
15 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 15

Moving on to step 2:
22 divided by 15 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 15 from 22 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 15

Advancing to step 3:
The number 15 fits into 78 5 times, leaving a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 75 from 78 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 15

Step 4:
34 divided by 15 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 152.0
Subtract 30 from 34 to get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 15

Step 5:
If we divide 49 by 15, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 1523.0
If we take 45 away from 49, we end up with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 15

On to step 6:
The number 15 fits into 45 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 15233.0
Deduct 45 from 45 and we're left with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 15

Going ahead to step 7:
2 divided by 15 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 152330.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 15

On to step 8:
15 can be fit into 29 1 times, resulting in a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1523301.0
If we subtract 15 from 29, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
140 divided by 15 is 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 1523301.9
Subtracting 135 from 140 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.

Advancing to step 10:
50 divided by 15 is 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 1523301.93
If we subtract 45 from 50, we get 5.
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 11:
When dividing 50 by 15, we get 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 1523301.933
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.

The final outcome is 1523301.933, with a leftover of 0.0005.
