We're dividing 89117523 by 287 
The aim is to understand the frequency of 287 in 89117523.

Let's proceed to step 1:
When dividing 8 by 287, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 287

Going ahead to step 2:
89 divided by 287 is 0 with a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 89 leaves us with 89.
Take the next digit (1) from the dividend and append it to 89, then repeat: 891 / 287

Step 3:
When dividing 891 by 287, we get 3 with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 30 after subtracting 861 from 891.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 287

Moving on to step 4:
When dividing 301 by 287, we get 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtracting 287 from 301 leaves us with 14.
Take the next digit (7) from the dividend and append it to 14, then repeat: 147 / 287

Step 5:
When dividing 147 by 287, we get 0 with a remainder of 147.
The next digit of our result is 0. 
Result so far: 310.0
Deduct 0 from 147 and we're left with 147.
Take the next digit (5) from the dividend and append it to 147, then repeat: 1475 / 287

On to step 6:
The number 287 fits into 1475 5 times, leaving a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 3105.0
If we take 1435 away from 1475, we end up with 40.
Append the next digit (2) from the dividend to 40 and continue with: 402 / 287

On to step 7:
If we divide 402 by 287, we get 1 and a remainder of 115.
Use 1 as the next digit of our solution. 
Result so far: 31051.0
If we take 287 away from 402, we end up with 115.
Grab the next digit (3) from the dividend, add it to 115, then carry on: 1153 / 287

Let's proceed to step 8:
The number 287 fits into 1153 4 times, leaving a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 310514.0
Deduct 1148 from 1153 and we're left with 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:
287 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 310514.0
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
287 goes into 500 1 times with a remainder of 213.
The number 1 becomes the next digit in our result. 
Result so far: 310514.01
Deduct 287 from 500 and we're left with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Step 11:
287 can be fit into 2130 7 times, resulting in a remainder of 121.
Put 7 as the next digit of the answer. 
Result so far: 310514.017
Deduct 2009 from 2130 and we're left with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Let's proceed to step 12:
The number 287 fits into 1210 4 times, leaving a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 310514.0174
The remainder is 62 after subtracting 1148 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 13:
When dividing 620 by 287, we get 2 with a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 310514.01742
The remainder is 46 after subtracting 574 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 14:
The number 287 fits into 460 1 times, leaving a remainder of 173.
Put 1 as the next digit of the answer. 
Result so far: 310514.017421
Deduct 287 from 460 and we're left with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Going ahead to step 15:
When dividing 1730 by 287, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 310514.0174216
If we take 1722 away from 1730, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 16:
287 goes into 80 0 times with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 310514.0174216
Subtract 0 from 80 to 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.

Our division results in 310514.0174216 with a remaining 8e-08.
