284407 divided by 87 
The aim is to understand the frequency of 87 in 284407.

Moving on to step 1:
The number 87 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 87

Advancing to step 2:
87 can be fit into 28 0 times, resulting in 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.
Fetch the next digit (4) from the dividend, attach it to 28 and continue: 284 / 87

Let's proceed to step 3:
If we divide 284 by 87, we get 3 and a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 261 away from 284, we end up with 23.
Take the next digit (4) from the dividend and append it to 23, then repeat: 234 / 87

Step 4:
87 goes into 234 2 times with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Deduct 174 from 234 and we're left with 60.
Bring next digit (0) of the dividend behind the 60 and repeat the process: 600 / 87

Moving on to step 5:
If we divide 600 by 87, we get 6 and a remainder of 78.
Use 6 as the next digit of our solution. 
Result so far: 326.0
Subtract 522 from 600 to get 78.
Append the next digit (7) from the dividend to 78 and continue with: 787 / 87

Advancing to step 6:
787 divided by 87 is 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 3269.0
Deduct 783 from 787 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
If we divide 40 by 87, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 3269.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
If we divide 400 by 87, we get 4 and a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 3269.04
Subtracting 348 from 400 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
When dividing 520 by 87, we get 5 with a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 3269.045
If we subtract 435 from 520, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 10:
850 divided by 87 is 9 with a remainder of 67.
The number 9 becomes the next digit in our result. 
Result so far: 3269.0459
If we subtract 783 from 850, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 11:
87 can be fit into 670 7 times, resulting in a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 3269.04597
Subtracting 609 from 670 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 12:
When dividing 610 by 87, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 3269.045977
Deduct 609 from 610 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 3269.045977 with a remainder of 1e-07.
