We look at the division of 90373308 by 254 
The aim is to understand the frequency of 254 in 90373308.

Advancing to step 1:
254 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 254

Advancing to step 2:
When dividing 90 by 254, we get 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Append the next digit (3) from the dividend to 90 and continue with: 903 / 254

Step 3:
903 divided by 254 is 3 with a remainder of 141.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 141 after subtracting 762 from 903.
Include the next digit (7) from the dividend after 141, then repeat: 1417 / 254

Advancing to step 4:
1417 divided by 254 is 5 with a remainder of 147.
The next digit of our result is 5. 
Result so far: 35.0
Subtract 1270 from 1417 to get 147.
Include the next digit (3) from the dividend after 147, then repeat: 1473 / 254

Moving on to step 5:
254 can be fit into 1473 5 times, resulting in a remainder of 203.
The number 5 becomes the next digit in our result. 
Result so far: 355.0
If we take 1270 away from 1473, we end up with 203.
Grab the next digit (3) from the dividend, add it to 203, then carry on: 2033 / 254

Moving on to step 6:
254 can be fit into 2033 8 times, resulting in a remainder of 1.
The next digit of our result is 8. 
Result so far: 3558.0
Subtracting 2032 from 2033 leaves us with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 254

On to step 7:
254 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 35580.0
Subtract 0 from 10 to get 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 254

On to step 8:
The number 254 fits into 108 0 times, leaving a remainder of 108.
The next digit of our result is 0. 
Result so far: 355800.0
If we take 0 away from 108, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 9:
254 goes into 1080 4 times with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 355800.4
Subtracting 1016 from 1080 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 10:
254 goes into 640 2 times with a remainder of 132.
The next digit of our result is 2. 
Result so far: 355800.42
If we subtract 508 from 640, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 11:
254 can be fit into 1320 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 355800.425
Deduct 1270 from 1320 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
When dividing 500 by 254, we get 1 with a remainder of 246.
The next digit of our result is 1. 
Result so far: 355800.4251
If we subtract 254 from 500, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Moving on to step 13:
The number 254 fits into 2460 9 times, leaving a remainder of 174.
Use 9 as the next digit of our solution. 
Result so far: 355800.42519
The remainder is 174 after subtracting 2286 from 2460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 14:
The number 254 fits into 1740 6 times, leaving a remainder of 216.
Use 6 as the next digit of our solution. 
Result so far: 355800.425196
Deduct 1524 from 1740 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 15:
The number 254 fits into 2160 8 times, leaving a remainder of 128.
Write down 8 as next digit of the result. 
Result so far: 355800.4251968
The remainder is 128 after subtracting 2032 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 16:
1280 divided by 254 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 355800.42519685
Subtracting 1270 from 1280 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 355800.42519685, with a leftover of 1e-08.
