We divide 15218859 by 459
The aim is to understand the frequency of 459 in 15218859.

Moving on to step 1:
459 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 459

On to step 2:
If we divide 15 by 459, we get 0 and a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 459

Moving on to step 3:
If we divide 152 by 459, we get 0 and a remainder of 152.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 152 after subtracting 0 from 152.
Fetch the next digit (1) from the dividend, attach it to 152 and continue: 1521 / 459

On to step 4:
If we divide 1521 by 459, we get 3 and a remainder of 144.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 1377 from 1521 and we're left with 144.
Append the next digit (8) from the dividend to 144 and continue with: 1448 / 459

Going ahead to step 5:
When dividing 1448 by 459, we get 3 with a remainder of 71.
Use 3 as the next digit of our solution. 
Result so far: 33.0
Deduct 1377 from 1448 and we're left with 71.
Fetch the next digit (8) from the dividend, attach it to 71 and continue: 718 / 459

Going ahead to step 6:
The number 459 fits into 718 1 times, leaving a remainder of 259.
The next digit of our result is 1. 
Result so far: 331.0
If we subtract 459 from 718, we get 259.
Include the next digit (5) from the dividend after 259, then repeat: 2595 / 459

Step 7:
459 goes into 2595 5 times with a remainder of 300.
Use 5 as the next digit of our solution. 
Result so far: 3315.0
If we subtract 2295 from 2595, we get 300.
Take the next digit (9) from the dividend and append it to 300, then repeat: 3009 / 459

Step 8:
If we divide 3009 by 459, we get 6 and a remainder of 255.
Put 6 as the next digit of the answer. 
Result so far: 33156.0
If we subtract 2754 from 3009, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 9:
459 can be fit into 2550 5 times, resulting in a remainder of 255.
The next digit of our result is 5. 
Result so far: 33156.5
If we take 2295 away from 2550, we end up with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Step 10:
459 goes into 2550 5 times with a remainder of 255.
Write down 5 as next digit of the result. 
Result so far: 33156.55
Subtracting 2295 from 2550 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

The final result is 33156.55 with a remainder of 0.255.
