We look at the division of 20159019 by 284 
The aim is to understand the frequency of 284 in 20159019.

Going ahead to step 1:
284 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 284

On to step 2:
If we divide 20 by 284, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 284

Going ahead to step 3:
284 can be fit into 201 0 times, resulting in a remainder of 201.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 201, we get 201.
Take the next digit (5) from the dividend and append it to 201, then repeat: 2015 / 284

Advancing to step 4:
When dividing 2015 by 284, we get 7 with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 1988 from 2015 and we're left with 27.
Include the next digit (9) from the dividend after 27, then repeat: 279 / 284

Moving on to step 5:
The number 284 fits into 279 0 times, leaving a remainder of 279.
The next digit of our result is 0. 
Result so far: 70.0
Subtracting 0 from 279 leaves us with 279.
Append the next digit (0) from the dividend to 279 and continue with: 2790 / 284

Going ahead to step 6:
284 can be fit into 2790 9 times, resulting in a remainder of 234.
The next digit of our result is 9. 
Result so far: 709.0
Subtract 2556 from 2790 to get 234.
Grab the next digit (1) from the dividend, add it to 234, then carry on: 2341 / 284

Step 7:
284 can be fit into 2341 8 times, resulting in a remainder of 69.
The number 8 becomes the next digit in our result. 
Result so far: 7098.0
Subtract 2272 from 2341 to get 69.
Include the next digit (9) from the dividend after 69, then repeat: 699 / 284

Let's proceed to step 8:
284 goes into 699 2 times with a remainder of 131.
The number 2 becomes the next digit in our result. 
Result so far: 70982.0
Deduct 568 from 699 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Moving on to step 9:
284 goes into 1310 4 times with a remainder of 174.
Put 4 as the next digit of the answer. 
Result so far: 70982.4
Deduct 1136 from 1310 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

On to step 10:
When dividing 1740 by 284, we get 6 with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 70982.46
If we subtract 1704 from 1740, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
When dividing 360 by 284, we get 1 with a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 70982.461
Subtracting 284 from 360 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 12:
284 can be fit into 760 2 times, resulting in a remainder of 192.
Use 2 as the next digit of our solution. 
Result so far: 70982.4612
If we take 568 away from 760, 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.

Moving on to step 13:
If we divide 1920 by 284, we get 6 and a remainder of 216.
The number 6 becomes the next digit in our result. 
Result so far: 70982.46126
If we take 1704 away from 1920, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 14:
When dividing 2160 by 284, we get 7 with a remainder of 172.
Write down 7 as next digit of the result. 
Result so far: 70982.461267
Deduct 1988 from 2160 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 15:
When dividing 1720 by 284, we get 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 70982.4612676
Subtract 1704 from 1720 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 16:
When dividing 160 by 284, we get 0 with a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 70982.4612676
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final outcome is 70982.4612676, with a leftover of 1.6e-07.
