We look at the division of 65499248 by 251 
The aim is to understand the frequency of 251 in 65499248.

Moving on to step 1:
The number 251 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 251

Going ahead to step 2:
The number 251 fits into 65 0 times, leaving a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Append the next digit (4) from the dividend to 65 and continue with: 654 / 251

Let's proceed to step 3:
If we divide 654 by 251, we get 2 and a remainder of 152.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 502 from 654 leaves us with 152.
Bring next digit (9) of the dividend behind the 152 and repeat the process: 1529 / 251

Moving on to step 4:
The number 251 fits into 1529 6 times, leaving a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Deduct 1506 from 1529 and we're left with 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 251

Going ahead to step 5:
The number 251 fits into 239 0 times, leaving a remainder of 239.
Use 0 as the next digit of our solution. 
Result so far: 260.0
Subtract 0 from 239 to get 239.
Append the next digit (2) from the dividend to 239 and continue with: 2392 / 251

On to step 6:
If we divide 2392 by 251, we get 9 and a remainder of 133.
Write down 9 as next digit of the result. 
Result so far: 2609.0
The remainder is 133 after subtracting 2259 from 2392.
Fetch the next digit (4) from the dividend, attach it to 133 and continue: 1334 / 251

On to step 7:
If we divide 1334 by 251, we get 5 and a remainder of 79.
Put 5 as the next digit of the answer. 
Result so far: 26095.0
Subtract 1255 from 1334 to get 79.
Include the next digit (8) from the dividend after 79, then repeat: 798 / 251

Advancing to step 8:
251 goes into 798 3 times with a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 260953.0
If we take 753 away from 798, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
251 goes into 450 1 times with a remainder of 199.
Use 1 as the next digit of our solution. 
Result so far: 260953.1
The remainder is 199 after subtracting 251 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

On to step 10:
251 can be fit into 1990 7 times, resulting in a remainder of 233.
The number 7 becomes the next digit in our result. 
Result so far: 260953.17
The remainder is 233 after subtracting 1757 from 1990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Step 11:
251 can be fit into 2330 9 times, resulting in a remainder of 71.
The next digit of our result is 9. 
Result so far: 260953.179
Subtracting 2259 from 2330 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 12:
710 divided by 251 is 2 with a remainder of 208.
Put 2 as the next digit of the answer. 
Result so far: 260953.1792
If we subtract 502 from 710, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 13:
If we divide 2080 by 251, we get 8 and a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 260953.17928
Subtracting 2008 from 2080 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 14:
251 can be fit into 720 2 times, resulting in a remainder of 218.
Write down 2 as next digit of the result. 
Result so far: 260953.179282
Deduct 502 from 720 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 15:
When dividing 2180 by 251, we get 8 with a remainder of 172.
The number 8 becomes the next digit in our result. 
Result so far: 260953.1792828
Deduct 2008 from 2180 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.

Moving on to step 16:
If we divide 1720 by 251, we get 6 and a remainder of 214.
Use 6 as the next digit of our solution. 
Result so far: 260953.17928286
If we subtract 1506 from 1720, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

After the division, we end up with 260953.17928286 and a remainder of 2.14e-07.
