We look at the division of 96399649 by 287 
The aim is to understand the frequency of 287 in 96399649.

Advancing to step 1:
287 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 287

On to step 2:
96 divided by 287 is 0 with a remainder of 96.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 96 and we're left with 96.
Include the next digit (3) from the dividend after 96, then repeat: 963 / 287

Moving on to step 3:
If we divide 963 by 287, we get 3 and a remainder of 102.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 861 from 963 leaves us with 102.
Grab the next digit (9) from the dividend, add it to 102, then carry on: 1029 / 287

Going ahead to step 4:
If we divide 1029 by 287, we get 3 and a remainder of 168.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
If we take 861 away from 1029, we end up with 168.
Grab the next digit (9) from the dividend, add it to 168, then carry on: 1689 / 287

Let's proceed to step 5:
The number 287 fits into 1689 5 times, leaving a remainder of 254.
Put 5 as the next digit of the answer. 
Result so far: 335.0
Subtracting 1435 from 1689 leaves us with 254.
Bring next digit (6) of the dividend behind the 254 and repeat the process: 2546 / 287

Let's proceed to step 6:
287 goes into 2546 8 times with a remainder of 250.
Record the quotient 8 as the next digit in the result. 
Result so far: 3358.0
Subtract 2296 from 2546 to get 250.
Bring next digit (4) of the dividend behind the 250 and repeat the process: 2504 / 287

Moving on to step 7:
2504 divided by 287 is 8 with a remainder of 208.
Write down 8 as next digit of the result. 
Result so far: 33588.0
If we take 2296 away from 2504, we end up with 208.
Bring next digit (9) of the dividend behind the 208 and repeat the process: 2089 / 287

Going ahead to step 8:
When dividing 2089 by 287, we get 7 with a remainder of 80.
The next digit of our result is 7. 
Result so far: 335887.0
If we subtract 2009 from 2089, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 9:
287 can be fit into 800 2 times, resulting in a remainder of 226.
Write down 2 as next digit of the result. 
Result so far: 335887.2
If we subtract 574 from 800, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Going ahead to step 10:
The number 287 fits into 2260 7 times, leaving a remainder of 251.
The number 7 becomes the next digit in our result. 
Result so far: 335887.27
Subtract 2009 from 2260 to get 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Moving on to step 11:
When dividing 2510 by 287, we get 8 with a remainder of 214.
The next digit of our result is 8. 
Result so far: 335887.278
If we subtract 2296 from 2510, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 12:
If we divide 2140 by 287, we get 7 and a remainder of 131.
Put 7 as the next digit of the answer. 
Result so far: 335887.2787
If we subtract 2009 from 2140, we get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Going ahead to step 13:
287 goes into 1310 4 times with a remainder of 162.
Write down 4 as next digit of the result. 
Result so far: 335887.27874
If we take 1148 away from 1310, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Advancing to step 14:
The number 287 fits into 1620 5 times, leaving a remainder of 185.
The next digit of our result is 5. 
Result so far: 335887.278745
Subtracting 1435 from 1620 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Moving on to step 15:
The number 287 fits into 1850 6 times, leaving a remainder of 128.
The number 6 becomes the next digit in our result. 
Result so far: 335887.2787456
Subtract 1722 from 1850 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 16:
287 can be fit into 1280 4 times, resulting in a remainder of 132.
Put 4 as the next digit of the answer. 
Result so far: 335887.27874564
If we take 1148 away from 1280, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

After the division, we end up with 335887.27874564 and a remainder of 1.32e-07.
