We're dividing 92379309 by 903 
The aim is to understand the frequency of 903 in 92379309.

Moving on to step 1:
The number 903 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 903

Advancing to step 2:
903 can be fit into 92 0 times, resulting in a remainder of 92.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 92 leaves us with 92.
Grab the next digit (3) from the dividend, add it to 92, then carry on: 923 / 903

Advancing to step 3:
When dividing 923 by 903, we get 1 with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 20 after subtracting 903 from 923.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 903

Going ahead to step 4:
The number 903 fits into 207 0 times, leaving a remainder of 207.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 207 leaves us with 207.
Grab the next digit (9) from the dividend, add it to 207, then carry on: 2079 / 903

On to step 5:
If we divide 2079 by 903, we get 2 and a remainder of 273.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
Subtract 1806 from 2079 to get 273.
Bring next digit (3) of the dividend behind the 273 and repeat the process: 2733 / 903

Let's proceed to step 6:
When dividing 2733 by 903, we get 3 with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 1023.0
The remainder is 24 after subtracting 2709 from 2733.
Include the next digit (0) from the dividend after 24, then repeat: 240 / 903

Going ahead to step 7:
If we divide 240 by 903, we get 0 and a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 10230.0
If we subtract 0 from 240, we get 240.
Bring next digit (9) of the dividend behind the 240 and repeat the process: 2409 / 903

On to step 8:
2409 divided by 903 is 2 with a remainder of 603.
Write down 2 as next digit of the result. 
Result so far: 102302.0
Deduct 1806 from 2409 and we're left with 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Going ahead to step 9:
When dividing 6030 by 903, we get 6 with a remainder of 612.
Use 6 as the next digit of our solution. 
Result so far: 102302.6
Subtract 5418 from 6030 to get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Let's proceed to step 10:
The number 903 fits into 6120 6 times, leaving a remainder of 702.
The number 6 becomes the next digit in our result. 
Result so far: 102302.66
Subtracting 5418 from 6120 leaves us with 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Our division results in 102302.66 with a remaining 0.702.
