703544 divided by 15 
The aim is to understand the frequency of 15 in 703544.

Advancing to step 1:
If we divide 7 by 15, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 15

On to step 2:
When dividing 70 by 15, we get 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 60 from 70, we get 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 15

Let's proceed to step 3:
When dividing 103 by 15, we get 6 with a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 46.0
If we subtract 90 from 103, we get 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 15

Going ahead to step 4:
15 goes into 135 9 times with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 469.0
If we take 135 away from 135, we end up with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 15

Let's proceed to step 5:
4 divided by 15 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 4690.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 15

Let's proceed to step 6:
The number 15 fits into 44 2 times, leaving a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 46902.0
If we subtract 30 from 44, 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 7:
If we divide 140 by 15, we get 9 and a remainder of 5.
The next digit of our result is 9. 
Result so far: 46902.9
If we take 135 away from 140, we end up 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.

Step 8:
50 divided by 15 is 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 46902.93
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.

Moving on to step 9:
50 divided by 15 is 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 46902.933
If we take 45 away from 50, we end up 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 result is 46902.933 with a remainder of 0.0005.
