42621880 divided by 281 
The aim is to understand the frequency of 281 in 42621880.

On to step 1:
4 divided by 281 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 281

On to step 2:
When dividing 42 by 281, we get 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (6) from the dividend after 42, then repeat: 426 / 281

Going ahead to step 3:
426 divided by 281 is 1 with a remainder of 145.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 281 from 426, we get 145.
Bring next digit (2) of the dividend behind the 145 and repeat the process: 1452 / 281

Step 4:
281 can be fit into 1452 5 times, resulting in a remainder of 47.
The next digit of our result is 5. 
Result so far: 15.0
If we take 1405 away from 1452, we end up with 47.
Take the next digit (1) from the dividend and append it to 47, then repeat: 471 / 281

Moving on to step 5:
281 goes into 471 1 times with a remainder of 190.
Record the quotient 1 as the next digit in the result. 
Result so far: 151.0
Subtracting 281 from 471 leaves us with 190.
Take the next digit (8) from the dividend and append it to 190, then repeat: 1908 / 281

Advancing to step 6:
281 can be fit into 1908 6 times, resulting in a remainder of 222.
Use 6 as the next digit of our solution. 
Result so far: 1516.0
Subtracting 1686 from 1908 leaves us with 222.
Take the next digit (8) from the dividend and append it to 222, then repeat: 2228 / 281

Going ahead to step 7:
If we divide 2228 by 281, we get 7 and a remainder of 261.
Put 7 as the next digit of the answer. 
Result so far: 15167.0
Subtract 1967 from 2228 to get 261.
Take the next digit (0) from the dividend and append it to 261, then repeat: 2610 / 281

On to step 8:
When dividing 2610 by 281, we get 9 with a remainder of 81.
Record the quotient 9 as the next digit in the result. 
Result so far: 151679.0
Subtracting 2529 from 2610 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 9:
The number 281 fits into 810 2 times, leaving a remainder of 248.
The next digit of our result is 2. 
Result so far: 151679.2
Subtracting 562 from 810 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 10:
2480 divided by 281 is 8 with a remainder of 232.
Put 8 as the next digit of the answer. 
Result so far: 151679.28
Subtracting 2248 from 2480 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 11:
If we divide 2320 by 281, we get 8 and a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 151679.288
If we subtract 2248 from 2320, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 151679.288 with a remainder of 0.0072.
