13073910 ÷ 287 
The aim is to understand the frequency of 287 in 13073910.

Let's proceed to step 1:
287 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 287

Moving on to step 2:
13 divided by 287 is 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 287

Advancing to step 3:
The number 287 fits into 130 0 times, leaving a remainder of 130.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 130 and we're left with 130.
Take the next digit (7) from the dividend and append it to 130, then repeat: 1307 / 287

Advancing to step 4:
287 goes into 1307 4 times with a remainder of 159.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 1148 from 1307 to get 159.
Include the next digit (3) from the dividend after 159, then repeat: 1593 / 287

Step 5:
The number 287 fits into 1593 5 times, leaving a remainder of 158.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtract 1435 from 1593 to get 158.
Bring next digit (9) of the dividend behind the 158 and repeat the process: 1589 / 287

Let's proceed to step 6:
1589 divided by 287 is 5 with a remainder of 154.
Write down 5 as next digit of the result. 
Result so far: 455.0
The remainder is 154 after subtracting 1435 from 1589.
Bring next digit (1) of the dividend behind the 154 and repeat the process: 1541 / 287

Let's proceed to step 7:
If we divide 1541 by 287, we get 5 and a remainder of 106.
Write down 5 as next digit of the result. 
Result so far: 4555.0
Subtracting 1435 from 1541 leaves us with 106.
Fetch the next digit (0) from the dividend, attach it to 106 and continue: 1060 / 287

Moving on to step 8:
When dividing 1060 by 287, we get 3 with a remainder of 199.
Put 3 as the next digit of the answer. 
Result so far: 45553.0
Deduct 861 from 1060 and we're left with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Moving on to step 9:
The number 287 fits into 1990 6 times, leaving a remainder of 268.
The number 6 becomes the next digit in our result. 
Result so far: 45553.6
Deduct 1722 from 1990 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Advancing to step 10:
287 goes into 2680 9 times with a remainder of 97.
Record the quotient 9 as the next digit in the result. 
Result so far: 45553.69
Subtract 2583 from 2680 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Going ahead to step 11:
If we divide 970 by 287, we get 3 and a remainder of 109.
Write down 3 as next digit of the result. 
Result so far: 45553.693
Subtracting 861 from 970 leaves us with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Step 12:
1090 divided by 287 is 3 with a remainder of 229.
Put 3 as the next digit of the answer. 
Result so far: 45553.6933
Subtracting 861 from 1090 leaves us with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

The final result is 45553.6933 with a remainder of 0.00229.
