We're dividing 87770549 by 287 
The aim is to understand the frequency of 287 in 87770549.

Moving on to step 1:
8 divided by 287 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 287

Advancing to step 2:
287 goes into 87 0 times with a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Append the next digit (7) from the dividend to 87 and continue with: 877 / 287

Moving on to step 3:
287 goes into 877 3 times with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 861 from 877 and we're left with 16.
Fetch the next digit (7) from the dividend, attach it to 16 and continue: 167 / 287

On to step 4:
287 goes into 167 0 times with a remainder of 167.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Subtract 0 from 167 to get 167.
Take the next digit (0) from the dividend and append it to 167, then repeat: 1670 / 287

On to step 5:
If we divide 1670 by 287, we get 5 and a remainder of 235.
Use 5 as the next digit of our solution. 
Result so far: 305.0
If we subtract 1435 from 1670, we get 235.
Append the next digit (5) from the dividend to 235 and continue with: 2355 / 287

On to step 6:
287 goes into 2355 8 times with a remainder of 59.
The next digit of our result is 8. 
Result so far: 3058.0
If we subtract 2296 from 2355, we get 59.
Bring next digit (4) of the dividend behind the 59 and repeat the process: 594 / 287

Going ahead to step 7:
594 divided by 287 is 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 30582.0
If we take 574 away from 594, we end up with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 287

Moving on to step 8:
287 goes into 209 0 times with a remainder of 209.
The next digit of our result is 0. 
Result so far: 305820.0
If we take 0 away from 209, we end up with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Going ahead to step 9:
2090 divided by 287 is 7 with a remainder of 81.
Write down 7 as next digit of the result. 
Result so far: 305820.7
Deduct 2009 from 2090 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 10:
287 goes into 810 2 times with a remainder of 236.
Write down 2 as next digit of the result. 
Result so far: 305820.72
Deduct 574 from 810 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 11:
2360 divided by 287 is 8 with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 305820.728
Subtracting 2296 from 2360 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
If we divide 640 by 287, we get 2 and a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 305820.7282
Subtract 574 from 640 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 13:
287 goes into 660 2 times with a remainder of 86.
Record the quotient 2 as the next digit in the result. 
Result so far: 305820.72822
Subtracting 574 from 660 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.

In conclusion, the division gives 305820.72822 with a balance of 8.6e-05.
