Let's divide 42992598 by 287
The aim is to understand the frequency of 287 in 42992598.

Advancing to step 1:
When dividing 4 by 287, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 287

Let's proceed to step 2:
If we divide 42 by 287, we get 0 and a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Bring next digit (9) of the dividend behind the 42 and repeat the process: 429 / 287

Going ahead to step 3:
287 can be fit into 429 1 times, resulting in a remainder of 142.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 287 from 429, we get 142.
Take the next digit (9) from the dividend and append it to 142, then repeat: 1429 / 287

Step 4:
If we divide 1429 by 287, we get 4 and a remainder of 281.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 281 after subtracting 1148 from 1429.
Append the next digit (2) from the dividend to 281 and continue with: 2812 / 287

Moving on to step 5:
When dividing 2812 by 287, we get 9 with a remainder of 229.
Use 9 as the next digit of our solution. 
Result so far: 149.0
If we take 2583 away from 2812, we end up with 229.
Take the next digit (5) from the dividend and append it to 229, then repeat: 2295 / 287

On to step 6:
When dividing 2295 by 287, we get 7 with a remainder of 286.
The next digit of our result is 7. 
Result so far: 1497.0
The remainder is 286 after subtracting 2009 from 2295.
Include the next digit (9) from the dividend after 286, then repeat: 2869 / 287

Step 7:
When dividing 2869 by 287, we get 9 with a remainder of 286.
Write down 9 as next digit of the result. 
Result so far: 14979.0
If we take 2583 away from 2869, we end up with 286.
Fetch the next digit (8) from the dividend, attach it to 286 and continue: 2868 / 287

Going ahead to step 8:
The number 287 fits into 2868 9 times, leaving a remainder of 285.
Write down 9 as next digit of the result. 
Result so far: 149799.0
Subtracting 2583 from 2868 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Advancing to step 9:
287 can be fit into 2850 9 times, resulting in a remainder of 267.
The number 9 becomes the next digit in our result. 
Result so far: 149799.9
If we subtract 2583 from 2850, we get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Moving on to step 10:
287 can be fit into 2670 9 times, resulting in a remainder of 87.
Record the quotient 9 as the next digit in the result. 
Result so far: 149799.99
Subtracting 2583 from 2670 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

The final outcome is 149799.99, with a leftover of 0.087.
