Let's divide 288308 by 87
The aim is to understand the frequency of 87 in 288308.

Let's proceed to step 1:
If we divide 2 by 87, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 87

Moving on to step 2:
If we divide 28 by 87, we get 0 and a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Append the next digit (8) from the dividend to 28 and continue with: 288 / 87

On to step 3:
87 goes into 288 3 times with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 261 from 288 leaves us with 27.
Take the next digit (3) from the dividend and append it to 27, then repeat: 273 / 87

On to step 4:
The number 87 fits into 273 3 times, leaving a remainder of 12.
The next digit of our result is 3. 
Result so far: 33.0
If we take 261 away from 273, we end up with 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 87

Going ahead to step 5:
87 goes into 120 1 times with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 331.0
If we subtract 87 from 120, we get 33.
Take the next digit (8) from the dividend and append it to 33, then repeat: 338 / 87

Let's proceed to step 6:
87 goes into 338 3 times with a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 3313.0
If we take 261 away from 338, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 7:
If we divide 770 by 87, we get 8 and a remainder of 74.
The number 8 becomes the next digit in our result. 
Result so far: 3313.8
Subtract 696 from 770 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 8:
If we divide 740 by 87, we get 8 and a remainder of 44.
The next digit of our result is 8. 
Result so far: 3313.88
The remainder is 44 after subtracting 696 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 3313.88, with a leftover of 0.044.
