Let's divide 38866908 by 903
The aim is to understand the frequency of 903 in 38866908.

Moving on to step 1:
If we divide 3 by 903, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 903

On to step 2:
903 can be fit into 38 0 times, resulting in a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Fetch the next digit (8) from the dividend, attach it to 38 and continue: 388 / 903

Let's proceed to step 3:
When dividing 388 by 903, we get 0 with a remainder of 388.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 388 leaves us with 388.
Include the next digit (6) from the dividend after 388, then repeat: 3886 / 903

On to step 4:
903 goes into 3886 4 times with a remainder of 274.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 3612 from 3886, we get 274.
Fetch the next digit (6) from the dividend, attach it to 274 and continue: 2746 / 903

On to step 5:
903 goes into 2746 3 times with a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Subtract 2709 from 2746 to get 37.
Bring next digit (9) of the dividend behind the 37 and repeat the process: 379 / 903

Advancing to step 6:
379 divided by 903 is 0 with a remainder of 379.
Write down 0 as next digit of the result. 
Result so far: 430.0
Deduct 0 from 379 and we're left with 379.
Bring next digit (0) of the dividend behind the 379 and repeat the process: 3790 / 903

Going ahead to step 7:
903 goes into 3790 4 times with a remainder of 178.
The next digit of our result is 4. 
Result so far: 4304.0
Subtracting 3612 from 3790 leaves us with 178.
Bring next digit (8) of the dividend behind the 178 and repeat the process: 1788 / 903

On to step 8:
The number 903 fits into 1788 1 times, leaving a remainder of 885.
The next digit of our result is 1. 
Result so far: 43041.0
Subtract 903 from 1788 to get 885.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8850, and continue the process.

Step 9:
903 can be fit into 8850 9 times, resulting in a remainder of 723.
Write down 9 as next digit of the result. 
Result so far: 43041.9
If we take 8127 away from 8850, we end up with 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

Moving on to step 10:
7230 divided by 903 is 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 43041.98
The remainder is 6 after subtracting 7224 from 7230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
903 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 43041.98
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 12:
600 divided by 903 is 0 with a remainder of 600.
The next digit of our result is 0. 
Result so far: 43041.98
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final outcome is 43041.98, with a leftover of 0.006.
