We look at the division of 18580010 by 766 
The aim is to understand the frequency of 766 in 18580010.

Let's proceed to step 1:
766 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 766

Let's proceed to step 2:
The number 766 fits into 18 0 times, leaving a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 766

Step 3:
When dividing 185 by 766, we get 0 with a remainder of 185.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 185 and we're left with 185.
Include the next digit (8) from the dividend after 185, then repeat: 1858 / 766

Moving on to step 4:
When dividing 1858 by 766, we get 2 with a remainder of 326.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 326 after subtracting 1532 from 1858.
Grab the next digit (0) from the dividend, add it to 326, then carry on: 3260 / 766

Advancing to step 5:
766 can be fit into 3260 4 times, resulting in a remainder of 196.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Deduct 3064 from 3260 and we're left with 196.
Bring next digit (0) of the dividend behind the 196 and repeat the process: 1960 / 766

Let's proceed to step 6:
766 goes into 1960 2 times with a remainder of 428.
Use 2 as the next digit of our solution. 
Result so far: 242.0
Subtract 1532 from 1960 to get 428.
Fetch the next digit (1) from the dividend, attach it to 428 and continue: 4281 / 766

Advancing to step 7:
766 can be fit into 4281 5 times, resulting in a remainder of 451.
Record the quotient 5 as the next digit in the result. 
Result so far: 2425.0
Subtracting 3830 from 4281 leaves us with 451.
Take the next digit (0) from the dividend and append it to 451, then repeat: 4510 / 766

On to step 8:
When dividing 4510 by 766, we get 5 with a remainder of 680.
The number 5 becomes the next digit in our result. 
Result so far: 24255.0
If we take 3830 away from 4510, we end up with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 9:
The number 766 fits into 6800 8 times, leaving a remainder of 672.
The number 8 becomes the next digit in our result. 
Result so far: 24255.8
The remainder is 672 after subtracting 6128 from 6800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

On to step 10:
766 can be fit into 6720 8 times, resulting in a remainder of 592.
Write down 8 as next digit of the result. 
Result so far: 24255.88
If we subtract 6128 from 6720, we get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

The quotient of the division is 24255.88, and the remainder is 0.592.
