18665287 divided by 748 
The aim is to understand the frequency of 748 in 18665287.

Let's proceed to step 1:
When dividing 1 by 748, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 748

Advancing to step 2:
The number 748 fits into 18 0 times, leaving a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 748

Let's proceed to step 3:
The number 748 fits into 186 0 times, leaving a remainder of 186.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 186 to get 186.
Append the next digit (6) from the dividend to 186 and continue with: 1866 / 748

Going ahead to step 4:
If we divide 1866 by 748, we get 2 and a remainder of 370.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 370 after subtracting 1496 from 1866.
Fetch the next digit (5) from the dividend, attach it to 370 and continue: 3705 / 748

On to step 5:
The number 748 fits into 3705 4 times, leaving a remainder of 713.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we subtract 2992 from 3705, we get 713.
Fetch the next digit (2) from the dividend, attach it to 713 and continue: 7132 / 748

Let's proceed to step 6:
7132 divided by 748 is 9 with a remainder of 400.
Use 9 as the next digit of our solution. 
Result so far: 249.0
Subtract 6732 from 7132 to get 400.
Include the next digit (8) from the dividend after 400, then repeat: 4008 / 748

Advancing to step 7:
When dividing 4008 by 748, we get 5 with a remainder of 268.
Record the quotient 5 as the next digit in the result. 
Result so far: 2495.0
The remainder is 268 after subtracting 3740 from 4008.
Take the next digit (7) from the dividend and append it to 268, then repeat: 2687 / 748

Going ahead to step 8:
748 goes into 2687 3 times with a remainder of 443.
The number 3 becomes the next digit in our result. 
Result so far: 24953.0
Subtracting 2244 from 2687 leaves us with 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Advancing to step 9:
The number 748 fits into 4430 5 times, leaving a remainder of 690.
Record the quotient 5 as the next digit in the result. 
Result so far: 24953.5
If we subtract 3740 from 4430, we get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Advancing to step 10:
If we divide 6900 by 748, we get 9 and a remainder of 168.
Use 9 as the next digit of our solution. 
Result so far: 24953.59
Deduct 6732 from 6900 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 11:
When dividing 1680 by 748, we get 2 with a remainder of 184.
The next digit of our result is 2. 
Result so far: 24953.592
The remainder is 184 after subtracting 1496 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 12:
748 goes into 1840 2 times with a remainder of 344.
Use 2 as the next digit of our solution. 
Result so far: 24953.5922
Subtract 1496 from 1840 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

The final result is 24953.5922 with a remainder of 0.00344.
