We look at the division of 11552704 by 251 
The aim is to understand the frequency of 251 in 11552704.

On to step 1:
1 divided by 251 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 251

Going ahead to step 2:
If we divide 11 by 251, we get 0 and a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 11, we end up with 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 251

Going ahead to step 3:
115 divided by 251 is 0 with a remainder of 115.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 115 leaves us with 115.
Include the next digit (5) from the dividend after 115, then repeat: 1155 / 251

Step 4:
251 goes into 1155 4 times with a remainder of 151.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 1004 from 1155 and we're left with 151.
Fetch the next digit (2) from the dividend, attach it to 151 and continue: 1512 / 251

Step 5:
251 goes into 1512 6 times with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
Subtracting 1506 from 1512 leaves us with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 251

Let's proceed to step 6:
251 can be fit into 67 0 times, resulting in a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 460.0
Deduct 0 from 67 and we're left with 67.
Bring next digit (0) of the dividend behind the 67 and repeat the process: 670 / 251

Advancing to step 7:
When dividing 670 by 251, we get 2 with a remainder of 168.
Write down 2 as next digit of the result. 
Result so far: 4602.0
If we subtract 502 from 670, we get 168.
Bring next digit (4) of the dividend behind the 168 and repeat the process: 1684 / 251

On to step 8:
The number 251 fits into 1684 6 times, leaving a remainder of 178.
Record the quotient 6 as the next digit in the result. 
Result so far: 46026.0
If we subtract 1506 from 1684, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Going ahead to step 9:
1780 divided by 251 is 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 46026.7
Subtracting 1757 from 1780 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 10:
The number 251 fits into 230 0 times, leaving a remainder of 230.
Put 0 as the next digit of the answer. 
Result so far: 46026.7
The remainder is 230 after subtracting 0 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 11:
251 can be fit into 2300 9 times, resulting in a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 46026.709
Subtracting 2259 from 2300 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 12:
The number 251 fits into 410 1 times, leaving a remainder of 159.
Use 1 as the next digit of our solution. 
Result so far: 46026.7091
If we subtract 251 from 410, we get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Going ahead to step 13:
If we divide 1590 by 251, we get 6 and a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 46026.70916
Subtracting 1506 from 1590 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 14:
If we divide 840 by 251, we get 3 and a remainder of 87.
Record the quotient 3 as the next digit in the result. 
Result so far: 46026.709163
If we take 753 away from 840, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 15:
If we divide 870 by 251, we get 3 and a remainder of 117.
Write down 3 as next digit of the result. 
Result so far: 46026.7091633
Subtracting 753 from 870 leaves us with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

The final result is 46026.7091633 with a remainder of 1.17e-06.
