42089188 ÷ 286 
The aim is to understand the frequency of 286 in 42089188.

Moving on to step 1:
4 divided by 286 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 286

Moving on to step 2:
42 divided by 286 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 286

Let's proceed to step 3:
When dividing 420 by 286, we get 1 with a remainder of 134.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 134 after subtracting 286 from 420.
Include the next digit (8) from the dividend after 134, then repeat: 1348 / 286

On to step 4:
The number 286 fits into 1348 4 times, leaving a remainder of 204.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 1144 from 1348 leaves us with 204.
Append the next digit (9) from the dividend to 204 and continue with: 2049 / 286

Let's proceed to step 5:
286 goes into 2049 7 times with a remainder of 47.
The number 7 becomes the next digit in our result. 
Result so far: 147.0
Subtract 2002 from 2049 to get 47.
Bring next digit (1) of the dividend behind the 47 and repeat the process: 471 / 286

Going ahead to step 6:
If we divide 471 by 286, we get 1 and a remainder of 185.
Put 1 as the next digit of the answer. 
Result so far: 1471.0
Subtract 286 from 471 to get 185.
Fetch the next digit (8) from the dividend, attach it to 185 and continue: 1858 / 286

On to step 7:
1858 divided by 286 is 6 with a remainder of 142.
Use 6 as the next digit of our solution. 
Result so far: 14716.0
Subtract 1716 from 1858 to get 142.
Take the next digit (8) from the dividend and append it to 142, then repeat: 1428 / 286

Advancing to step 8:
1428 divided by 286 is 4 with a remainder of 284.
Write down 4 as next digit of the result. 
Result so far: 147164.0
Subtract 1144 from 1428 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 9:
When dividing 2840 by 286, we get 9 with a remainder of 266.
The next digit of our result is 9. 
Result so far: 147164.9
If we take 2574 away from 2840, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 10:
When dividing 2660 by 286, we get 9 with a remainder of 86.
The next digit of our result is 9. 
Result so far: 147164.99
If we take 2574 away from 2660, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final result is 147164.99 with a remainder of 0.086.
