239537 divided by 87 
The aim is to understand the frequency of 87 in 239537.

Moving on to step 1:
If we divide 2 by 87, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 87

Let's proceed to step 2:
23 divided by 87 is 0 with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 87

On to step 3:
When dividing 239 by 87, we get 2 with a remainder of 65.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 174 from 239, we get 65.
Include the next digit (5) from the dividend after 65, then repeat: 655 / 87

Moving on to step 4:
87 goes into 655 7 times with a remainder of 46.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Deduct 609 from 655 and we're left with 46.
Include the next digit (3) from the dividend after 46, then repeat: 463 / 87

Going ahead to step 5:
87 can be fit into 463 5 times, resulting in a remainder of 28.
Write down 5 as next digit of the result. 
Result so far: 275.0
If we take 435 away from 463, we end up with 28.
Append the next digit (7) from the dividend to 28 and continue with: 287 / 87

Advancing to step 6:
87 goes into 287 3 times with a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 2753.0
Deduct 261 from 287 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 7:
If we divide 260 by 87, we get 2 and a remainder of 86.
Record the quotient 2 as the next digit in the result. 
Result so far: 2753.2
Subtracting 174 from 260 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 8:
87 can be fit into 860 9 times, resulting in a remainder of 77.
The number 9 becomes the next digit in our result. 
Result so far: 2753.29
Deduct 783 from 860 and we're left 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.

Advancing to step 9:
87 can be fit into 770 8 times, resulting in a remainder of 74.
The number 8 becomes the next digit in our result. 
Result so far: 2753.298
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.

Let's proceed to step 10:
87 can be fit into 740 8 times, resulting in a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 2753.2988
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.

Our division results in 2753.2988 with a remaining 0.00044.
