We look at the division of 4273851 by 284 
The aim is to understand the frequency of 284 in 4273851.

Step 1:
284 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 284

Advancing to step 2:
42 divided by 284 is 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (7) from the dividend after 42, then repeat: 427 / 284

Advancing to step 3:
The number 284 fits into 427 1 times, leaving a remainder of 143.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 284 away from 427, we end up with 143.
Grab the next digit (3) from the dividend, add it to 143, then carry on: 1433 / 284

Going ahead to step 4:
If we divide 1433 by 284, we get 5 and a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 1420 from 1433 to get 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 284

Advancing to step 5:
When dividing 138 by 284, we get 0 with a remainder of 138.
Use 0 as the next digit of our solution. 
Result so far: 150.0
If we subtract 0 from 138, we get 138.
Fetch the next digit (5) from the dividend, attach it to 138 and continue: 1385 / 284

Going ahead to step 6:
284 goes into 1385 4 times with a remainder of 249.
Write down 4 as next digit of the result. 
Result so far: 1504.0
The remainder is 249 after subtracting 1136 from 1385.
Bring next digit (1) of the dividend behind the 249 and repeat the process: 2491 / 284

Let's proceed to step 7:
2491 divided by 284 is 8 with a remainder of 219.
Use 8 as the next digit of our solution. 
Result so far: 15048.0
If we take 2272 away from 2491, we end up with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Moving on to step 8:
When dividing 2190 by 284, we get 7 with a remainder of 202.
Record the quotient 7 as the next digit in the result. 
Result so far: 15048.7
Subtract 1988 from 2190 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 9:
When dividing 2020 by 284, we get 7 with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 15048.77
Deduct 1988 from 2020 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 15048.77 and a remainder of 0.032.
