We look at the division of 65214660 by 286 
The aim is to understand the frequency of 286 in 65214660.

Step 1:
6 divided by 286 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 286

On to step 2:
286 goes into 65 0 times with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Grab the next digit (2) from the dividend, add it to 65, then carry on: 652 / 286

Advancing to step 3:
286 goes into 652 2 times with a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 572 away from 652, we end up with 80.
Append the next digit (1) from the dividend to 80 and continue with: 801 / 286

On to step 4:
286 can be fit into 801 2 times, resulting in a remainder of 229.
The next digit of our result is 2. 
Result so far: 22.0
If we subtract 572 from 801, we get 229.
Take the next digit (4) from the dividend and append it to 229, then repeat: 2294 / 286

On to step 5:
286 goes into 2294 8 times with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 228.0
Subtracting 2288 from 2294 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 286

Step 6:
When dividing 66 by 286, we get 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 2280.0
If we subtract 0 from 66, we get 66.
Take the next digit (6) from the dividend and append it to 66, then repeat: 666 / 286

Going ahead to step 7:
666 divided by 286 is 2 with a remainder of 94.
Record the quotient 2 as the next digit in the result. 
Result so far: 22802.0
If we take 572 away from 666, we end up with 94.
Append the next digit (0) from the dividend to 94 and continue with: 940 / 286

Moving on to step 8:
If we divide 940 by 286, we get 3 and a remainder of 82.
The next digit of our result is 3. 
Result so far: 228023.0
The remainder is 82 after subtracting 858 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 9:
820 divided by 286 is 2 with a remainder of 248.
Put 2 as the next digit of the answer. 
Result so far: 228023.2
Subtract 572 from 820 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 10:
2480 divided by 286 is 8 with a remainder of 192.
Use 8 as the next digit of our solution. 
Result so far: 228023.28
If we take 2288 away from 2480, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 11:
If we divide 1920 by 286, we get 6 and a remainder of 204.
The number 6 becomes the next digit in our result. 
Result so far: 228023.286
Subtracting 1716 from 1920 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 12:
2040 divided by 286 is 7 with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 228023.2867
Subtract 2002 from 2040 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 13:
380 divided by 286 is 1 with a remainder of 94.
Record the quotient 1 as the next digit in the result. 
Result so far: 228023.28671
Subtracting 286 from 380 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 14:
When dividing 940 by 286, we get 3 with a remainder of 82.
The number 3 becomes the next digit in our result. 
Result so far: 228023.286713
Deduct 858 from 940 and we're left 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.

Moving on to step 15:
When dividing 820 by 286, we get 2 with a remainder of 248.
Use 2 as the next digit of our solution. 
Result so far: 228023.2867132
If we take 572 away from 820, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 16:
286 goes into 2480 8 times with a remainder of 192.
The next digit of our result is 8. 
Result so far: 228023.28671328
Subtracting 2288 from 2480 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Our division results in 228023.28671328 with a remaining 1.92e-07.
