Let's divide 43580973 by 287
The aim is to understand the frequency of 287 in 43580973.

Moving on to step 1:
287 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 287

Moving on to step 2:
When dividing 43 by 287, we get 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (5) from the dividend, attach it to 43 and continue: 435 / 287

Moving on to step 3:
The number 287 fits into 435 1 times, leaving a remainder of 148.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 287 from 435 to get 148.
Grab the next digit (8) from the dividend, add it to 148, then carry on: 1488 / 287

Step 4:
The number 287 fits into 1488 5 times, leaving a remainder of 53.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 1435 from 1488, we get 53.
Include the next digit (0) from the dividend after 53, then repeat: 530 / 287

Moving on to step 5:
When dividing 530 by 287, we get 1 with a remainder of 243.
Write down 1 as next digit of the result. 
Result so far: 151.0
Deduct 287 from 530 and we're left with 243.
Append the next digit (9) from the dividend to 243 and continue with: 2439 / 287

On to step 6:
The number 287 fits into 2439 8 times, leaving a remainder of 143.
Record the quotient 8 as the next digit in the result. 
Result so far: 1518.0
If we take 2296 away from 2439, we end up with 143.
Include the next digit (7) from the dividend after 143, then repeat: 1437 / 287

Going ahead to step 7:
1437 divided by 287 is 5 with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 15185.0
Subtract 1435 from 1437 to get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 287

Moving on to step 8:
287 goes into 23 0 times with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 151850.0
Deduct 0 from 23 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 9:
The number 287 fits into 230 0 times, leaving a remainder of 230.
Use 0 as the next digit of our solution. 
Result so far: 151850.0
If we take 0 away from 230, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 10:
When dividing 2300 by 287, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 151850.08
Subtracting 2296 from 2300 leaves us 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.

Advancing to step 11:
287 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 151850.08
If we subtract 0 from 40, we 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.

Moving on to step 12:
The number 287 fits into 400 1 times, leaving a remainder of 113.
Use 1 as the next digit of our solution. 
Result so far: 151850.0801
Deduct 287 from 400 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Advancing to step 13:
If we divide 1130 by 287, we get 3 and a remainder of 269.
Record the quotient 3 as the next digit in the result. 
Result so far: 151850.08013
The remainder is 269 after subtracting 861 from 1130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

On to step 14:
2690 divided by 287 is 9 with a remainder of 107.
The next digit of our result is 9. 
Result so far: 151850.080139
Subtracting 2583 from 2690 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Moving on to step 15:
When dividing 1070 by 287, we get 3 with a remainder of 209.
The next digit of our result is 3. 
Result so far: 151850.0801393
Deduct 861 from 1070 and we're left 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.

On to step 16:
If we divide 2090 by 287, we get 7 and a remainder of 81.
The next digit of our result is 7. 
Result so far: 151850.08013937
If we take 2009 away from 2090, we end up 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.

In conclusion, the division gives 151850.08013937 with a balance of 8.1e-08.
