87043142 ÷ 281 
The aim is to understand the frequency of 281 in 87043142.

Going ahead to step 1:
If we divide 8 by 281, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 281

Let's proceed to step 2:
281 goes into 87 0 times with a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Take the next digit (0) from the dividend and append it to 87, then repeat: 870 / 281

Let's proceed to step 3:
If we divide 870 by 281, we get 3 and a remainder of 27.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 843 from 870 to get 27.
Include the next digit (4) from the dividend after 27, then repeat: 274 / 281

On to step 4:
274 divided by 281 is 0 with a remainder of 274.
The next digit of our result is 0. 
Result so far: 30.0
Deduct 0 from 274 and we're left with 274.
Fetch the next digit (3) from the dividend, attach it to 274 and continue: 2743 / 281

Going ahead to step 5:
281 can be fit into 2743 9 times, resulting in a remainder of 214.
Use 9 as the next digit of our solution. 
Result so far: 309.0
Subtract 2529 from 2743 to get 214.
Take the next digit (1) from the dividend and append it to 214, then repeat: 2141 / 281

Step 6:
2141 divided by 281 is 7 with a remainder of 174.
Write down 7 as next digit of the result. 
Result so far: 3097.0
If we subtract 1967 from 2141, we get 174.
Append the next digit (4) from the dividend to 174 and continue with: 1744 / 281

Going ahead to step 7:
The number 281 fits into 1744 6 times, leaving a remainder of 58.
Put 6 as the next digit of the answer. 
Result so far: 30976.0
Subtract 1686 from 1744 to get 58.
Fetch the next digit (2) from the dividend, attach it to 58 and continue: 582 / 281

Moving on to step 8:
If we divide 582 by 281, we get 2 and a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 309762.0
If we subtract 562 from 582, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
The number 281 fits into 200 0 times, leaving a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 309762.0
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 10:
The number 281 fits into 2000 7 times, leaving a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 309762.07
Deduct 1967 from 2000 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 11:
The number 281 fits into 330 1 times, leaving a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 309762.071
If we take 281 away from 330, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 12:
490 divided by 281 is 1 with a remainder of 209.
The number 1 becomes the next digit in our result. 
Result so far: 309762.0711
The remainder is 209 after subtracting 281 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Our division results in 309762.0711 with a remaining 0.00209.
