We're dividing 16458982 by 251 
The aim is to understand the frequency of 251 in 16458982.

Moving on to step 1:
The number 251 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 251

Step 2:
16 divided by 251 is 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 251

Let's proceed to step 3:
251 can be fit into 164 0 times, resulting in a remainder of 164.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 164 to get 164.
Fetch the next digit (5) from the dividend, attach it to 164 and continue: 1645 / 251

On to step 4:
The number 251 fits into 1645 6 times, leaving a remainder of 139.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 1506 from 1645, we get 139.
Fetch the next digit (8) from the dividend, attach it to 139 and continue: 1398 / 251

Going ahead to step 5:
251 can be fit into 1398 5 times, resulting in a remainder of 143.
Write down 5 as next digit of the result. 
Result so far: 65.0
The remainder is 143 after subtracting 1255 from 1398.
Append the next digit (9) from the dividend to 143 and continue with: 1439 / 251

Advancing to step 6:
251 can be fit into 1439 5 times, resulting in a remainder of 184.
Record the quotient 5 as the next digit in the result. 
Result so far: 655.0
Subtracting 1255 from 1439 leaves us with 184.
Grab the next digit (8) from the dividend, add it to 184, then carry on: 1848 / 251

Advancing to step 7:
If we divide 1848 by 251, we get 7 and a remainder of 91.
Use 7 as the next digit of our solution. 
Result so far: 6557.0
The remainder is 91 after subtracting 1757 from 1848.
Fetch the next digit (2) from the dividend, attach it to 91 and continue: 912 / 251

Going ahead to step 8:
251 goes into 912 3 times with a remainder of 159.
Write down 3 as next digit of the result. 
Result so far: 65573.0
Subtracting 753 from 912 leaves us with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Advancing to step 9:
If we divide 1590 by 251, we get 6 and a remainder of 84.
The next digit of our result is 6. 
Result so far: 65573.6
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.

Moving on to step 10:
251 goes into 840 3 times with a remainder of 87.
The next digit of our result is 3. 
Result so far: 65573.63
Deduct 753 from 840 and we're left 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.

Let's proceed to step 11:
251 goes into 870 3 times with a remainder of 117.
Put 3 as the next digit of the answer. 
Result so far: 65573.633
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 quotient of the division is 65573.633, and the remainder is 0.0117.
