Let's divide 281388 by 87
The aim is to understand the frequency of 87 in 281388.

On to step 1:
If we divide 2 by 87, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 87

Advancing to step 2:
If we divide 28 by 87, we get 0 and a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Fetch the next digit (1) from the dividend, attach it to 28 and continue: 281 / 87

Going ahead to step 3:
281 divided by 87 is 3 with a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 261 from 281, we get 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 87

On to step 4:
87 can be fit into 203 2 times, resulting in a remainder of 29.
The next digit of our result is 2. 
Result so far: 32.0
Deduct 174 from 203 and we're left with 29.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 87

Advancing to step 5:
87 goes into 298 3 times with a remainder of 37.
The next digit of our result is 3. 
Result so far: 323.0
If we take 261 away from 298, we end up with 37.
Fetch the next digit (8) from the dividend, attach it to 37 and continue: 378 / 87

Going ahead to step 6:
If we divide 378 by 87, we get 4 and a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 3234.0
Subtract 348 from 378 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
87 goes into 300 3 times with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 3234.3
If we subtract 261 from 300, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 8:
If we divide 390 by 87, we get 4 and a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 3234.34
Subtract 348 from 390 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 9:
87 goes into 420 4 times with a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 3234.344
Subtract 348 from 420 to 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 outcome is 3234.344, with a leftover of 0.0072.
