We're dividing 243038 by 87 
The aim is to understand the frequency of 87 in 243038.

On to step 1:
If we divide 2 by 87, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 87

Moving on to step 2:
The number 87 fits into 24 0 times, leaving a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 24, we get 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 87

Going ahead to step 3:
87 goes into 243 2 times with a remainder of 69.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 69 after subtracting 174 from 243.
Include the next digit (0) from the dividend after 69, then repeat: 690 / 87

Let's proceed to step 4:
87 goes into 690 7 times with a remainder of 81.
Put 7 as the next digit of the answer. 
Result so far: 27.0
If we subtract 609 from 690, we get 81.
Append the next digit (3) from the dividend to 81 and continue with: 813 / 87

Step 5:
813 divided by 87 is 9 with a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 279.0
The remainder is 30 after subtracting 783 from 813.
Fetch the next digit (8) from the dividend, attach it to 30 and continue: 308 / 87

Advancing to step 6:
When dividing 308 by 87, we get 3 with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 2793.0
Subtracting 261 from 308 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 7:
470 divided by 87 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 2793.5
If we take 435 away from 470, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 8:
The number 87 fits into 350 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 2793.54
If we take 348 away from 350, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
87 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 2793.54
If we subtract 0 from 20, 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.

Going ahead to step 10:
87 can be fit into 200 2 times, resulting in a remainder of 26.
The next digit of our result is 2. 
Result so far: 2793.5402
If we take 174 away from 200, we end up 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.

On to step 11:
260 divided by 87 is 2 with a remainder of 86.
Write down 2 as next digit of the result. 
Result so far: 2793.54022
If we take 174 away from 260, we end up 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.

The final outcome is 2793.54022, with a leftover of 8.6e-05.
