Let's divide 42982391 by 287
The aim is to understand the frequency of 287 in 42982391.

Moving on to step 1:
The number 287 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 287

Advancing to step 2:
287 goes into 42 0 times with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Grab the next digit (9) from the dividend, add it to 42, then carry on: 429 / 287

Moving on to step 3:
The number 287 fits into 429 1 times, leaving a remainder of 142.
The next digit of our result is 1. 
Result so far: 1.0
If we take 287 away from 429, we end up with 142.
Take the next digit (8) from the dividend and append it to 142, then repeat: 1428 / 287

Let's proceed to step 4:
The number 287 fits into 1428 4 times, leaving a remainder of 280.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 280 after subtracting 1148 from 1428.
Append the next digit (2) from the dividend to 280 and continue with: 2802 / 287

Advancing to step 5:
287 goes into 2802 9 times with a remainder of 219.
Write down 9 as next digit of the result. 
Result so far: 149.0
If we take 2583 away from 2802, we end up with 219.
Fetch the next digit (3) from the dividend, attach it to 219 and continue: 2193 / 287

Step 6:
When dividing 2193 by 287, we get 7 with a remainder of 184.
Put 7 as the next digit of the answer. 
Result so far: 1497.0
The remainder is 184 after subtracting 2009 from 2193.
Grab the next digit (9) from the dividend, add it to 184, then carry on: 1849 / 287

Let's proceed to step 7:
The number 287 fits into 1849 6 times, leaving a remainder of 127.
The number 6 becomes the next digit in our result. 
Result so far: 14976.0
If we subtract 1722 from 1849, we get 127.
Append the next digit (1) from the dividend to 127 and continue with: 1271 / 287

Advancing to step 8:
If we divide 1271 by 287, we get 4 and a remainder of 123.
Use 4 as the next digit of our solution. 
Result so far: 149764.0
Subtracting 1148 from 1271 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 9:
When dividing 1230 by 287, we get 4 with a remainder of 82.
The next digit of our result is 4. 
Result so far: 149764.4
If we take 1148 away from 1230, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 10:
287 can be fit into 820 2 times, resulting in a remainder of 246.
The next digit of our result is 2. 
Result so far: 149764.42
Subtracting 574 from 820 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Moving on to step 11:
2460 divided by 287 is 8 with a remainder of 164.
Use 8 as the next digit of our solution. 
Result so far: 149764.428
If we take 2296 away from 2460, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 12:
287 can be fit into 1640 5 times, resulting in a remainder of 205.
The next digit of our result is 5. 
Result so far: 149764.4285
Subtracting 1435 from 1640 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Moving on to step 13:
287 goes into 2050 7 times with a remainder of 41.
The next digit of our result is 7. 
Result so far: 149764.42857
Subtracting 2009 from 2050 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 14:
When dividing 410 by 287, we get 1 with a remainder of 123.
The number 1 becomes the next digit in our result. 
Result so far: 149764.428571
Subtracting 287 from 410 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 15:
1230 divided by 287 is 4 with a remainder of 82.
Use 4 as the next digit of our solution. 
Result so far: 149764.4285714
If we subtract 1148 from 1230, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 16:
820 divided by 287 is 2 with a remainder of 246.
The next digit of our result is 2. 
Result so far: 149764.42857142
Deduct 574 from 820 and we're left with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Our division results in 149764.42857142 with a remaining 2.46e-07.
