Let's divide 28459121 by 251
The aim is to understand the frequency of 251 in 28459121.

Moving on to step 1:
2 divided by 251 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 251

Moving on to step 2:
251 goes into 28 0 times with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 251

Step 3:
251 goes into 284 1 times with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 251 from 284 to get 33.
Take the next digit (5) from the dividend and append it to 33, then repeat: 335 / 251

Let's proceed to step 4:
The number 251 fits into 335 1 times, leaving a remainder of 84.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 251 from 335 to get 84.
Include the next digit (9) from the dividend after 84, then repeat: 849 / 251

Advancing to step 5:
If we divide 849 by 251, we get 3 and a remainder of 96.
Write down 3 as next digit of the result. 
Result so far: 113.0
Subtracting 753 from 849 leaves us with 96.
Bring next digit (1) of the dividend behind the 96 and repeat the process: 961 / 251

Going ahead to step 6:
If we divide 961 by 251, we get 3 and a remainder of 208.
Record the quotient 3 as the next digit in the result. 
Result so far: 1133.0
Subtract 753 from 961 to get 208.
Take the next digit (2) from the dividend and append it to 208, then repeat: 2082 / 251

Step 7:
If we divide 2082 by 251, we get 8 and a remainder of 74.
Put 8 as the next digit of the answer. 
Result so far: 11338.0
The remainder is 74 after subtracting 2008 from 2082.
Include the next digit (1) from the dividend after 74, then repeat: 741 / 251

On to step 8:
741 divided by 251 is 2 with a remainder of 239.
Put 2 as the next digit of the answer. 
Result so far: 113382.0
The remainder is 239 after subtracting 502 from 741.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

On to step 9:
251 can be fit into 2390 9 times, resulting in a remainder of 131.
The next digit of our result is 9. 
Result so far: 113382.9
If we take 2259 away from 2390, we end up 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.

Going ahead to step 10:
When dividing 1310 by 251, we get 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 113382.95
If we subtract 1255 from 1310, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 11:
When dividing 550 by 251, we get 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 113382.952
The remainder is 48 after subtracting 502 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 12:
480 divided by 251 is 1 with a remainder of 229.
The number 1 becomes the next digit in our result. 
Result so far: 113382.9521
The remainder is 229 after subtracting 251 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Let's proceed to step 13:
2290 divided by 251 is 9 with a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 113382.95219
The remainder is 31 after subtracting 2259 from 2290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 14:
If we divide 310 by 251, we get 1 and a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 113382.952191
Deduct 251 from 310 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 15:
251 goes into 590 2 times with a remainder of 88.
Put 2 as the next digit of the answer. 
Result so far: 113382.9521912
If we take 502 away from 590, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 16:
251 goes into 880 3 times with a remainder of 127.
The number 3 becomes the next digit in our result. 
Result so far: 113382.95219123
Deduct 753 from 880 and we're left with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

The final outcome is 113382.95219123, with a leftover of 1.27e-07.
