We look at the division of 11805310 by 281 
The aim is to understand the frequency of 281 in 11805310.

Advancing to step 1:
281 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 281

Moving on to step 2:
If we divide 11 by 281, we get 0 and a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 281

On to step 3:
281 goes into 118 0 times with a remainder of 118.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 118 leaves us with 118.
Take the next digit (0) from the dividend and append it to 118, then repeat: 1180 / 281

Moving on to step 4:
281 can be fit into 1180 4 times, resulting in a remainder of 56.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 56 after subtracting 1124 from 1180.
Bring next digit (5) of the dividend behind the 56 and repeat the process: 565 / 281

Advancing to step 5:
When dividing 565 by 281, we get 2 with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Subtracting 562 from 565 leaves us with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 281

Advancing to step 6:
281 goes into 33 0 times with a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 420.0
If we take 0 away from 33, we end up with 33.
Append the next digit (1) from the dividend to 33 and continue with: 331 / 281

Moving on to step 7:
281 goes into 331 1 times with a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 4201.0
Subtracting 281 from 331 leaves us with 50.
Bring next digit (0) of the dividend behind the 50 and repeat the process: 500 / 281

Step 8:
281 can be fit into 500 1 times, resulting in a remainder of 219.
Use 1 as the next digit of our solution. 
Result so far: 42011.0
If we subtract 281 from 500, we get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Step 9:
If we divide 2190 by 281, we get 7 and a remainder of 223.
The number 7 becomes the next digit in our result. 
Result so far: 42011.7
Subtracting 1967 from 2190 leaves us with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

On to step 10:
281 can be fit into 2230 7 times, resulting in a remainder of 263.
Use 7 as the next digit of our solution. 
Result so far: 42011.77
If we subtract 1967 from 2230, we get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

The final outcome is 42011.77, with a leftover of 0.263.
