247850 divided by 87 
The aim is to understand the frequency of 87 in 247850.

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.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 87

Moving on to step 2:
87 goes into 24 0 times with a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 24 and we're left with 24.
Include the next digit (7) from the dividend after 24, then repeat: 247 / 87

Going ahead to step 3:
247 divided by 87 is 2 with a remainder of 73.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 174 from 247 and we're left with 73.
Bring next digit (8) of the dividend behind the 73 and repeat the process: 738 / 87

Moving on to step 4:
The number 87 fits into 738 8 times, leaving a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Subtracting 696 from 738 leaves us with 42.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 87

Advancing to step 5:
The number 87 fits into 425 4 times, leaving a remainder of 77.
Record the quotient 4 as the next digit in the result. 
Result so far: 284.0
If we take 348 away from 425, we end up with 77.
Fetch the next digit (0) from the dividend, attach it to 77 and continue: 770 / 87

On to step 6:
87 can be fit into 770 8 times, resulting in a remainder of 74.
Record the quotient 8 as the next digit in the result. 
Result so far: 2848.0
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.

Going ahead to step 7:
The number 87 fits into 740 8 times, leaving a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 2848.8
If we subtract 696 from 740, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 8:
440 divided by 87 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 2848.85
If we subtract 435 from 440, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
50 divided by 87 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 2848.85
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
87 goes into 500 5 times with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 2848.8505
The remainder is 65 after subtracting 435 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 11:
87 goes into 650 7 times with a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 2848.85057
Deduct 609 from 650 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 12:
87 can be fit into 410 4 times, resulting in a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 2848.850574
Subtract 348 from 410 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 13:
The number 87 fits into 620 7 times, leaving a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 2848.8505747
Subtract 609 from 620 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 14:
If we divide 110 by 87, we get 1 and a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 2848.85057471
If we subtract 87 from 110, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final result is 2848.85057471 with a remainder of 2.3e-08.
