38740324 divided by 766 
The aim is to understand the frequency of 766 in 38740324.

Step 1:
3 divided by 766 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 766

Going ahead to step 2:
766 goes into 38 0 times with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Grab the next digit (7) from the dividend, add it to 38, then carry on: 387 / 766

Step 3:
When dividing 387 by 766, we get 0 with a remainder of 387.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 387 and we're left with 387.
Bring next digit (4) of the dividend behind the 387 and repeat the process: 3874 / 766

Moving on to step 4:
3874 divided by 766 is 5 with a remainder of 44.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 3830 from 3874 leaves us with 44.
Include the next digit (0) from the dividend after 44, then repeat: 440 / 766

On to step 5:
When dividing 440 by 766, we get 0 with a remainder of 440.
The next digit of our result is 0. 
Result so far: 50.0
Deduct 0 from 440 and we're left with 440.
Include the next digit (3) from the dividend after 440, then repeat: 4403 / 766

Going ahead to step 6:
When dividing 4403 by 766, we get 5 with a remainder of 573.
Put 5 as the next digit of the answer. 
Result so far: 505.0
Deduct 3830 from 4403 and we're left with 573.
Bring next digit (2) of the dividend behind the 573 and repeat the process: 5732 / 766

On to step 7:
766 can be fit into 5732 7 times, resulting in a remainder of 370.
Write down 7 as next digit of the result. 
Result so far: 5057.0
Subtracting 5362 from 5732 leaves us with 370.
Grab the next digit (4) from the dividend, add it to 370, then carry on: 3704 / 766

Let's proceed to step 8:
The number 766 fits into 3704 4 times, leaving a remainder of 640.
Use 4 as the next digit of our solution. 
Result so far: 50574.0
If we subtract 3064 from 3704, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 9:
The number 766 fits into 6400 8 times, leaving a remainder of 272.
Use 8 as the next digit of our solution. 
Result so far: 50574.8
If we take 6128 away from 6400, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Moving on to step 10:
The number 766 fits into 2720 3 times, leaving a remainder of 422.
The number 3 becomes the next digit in our result. 
Result so far: 50574.83
The remainder is 422 after subtracting 2298 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Let's proceed to step 11:
If we divide 4220 by 766, we get 5 and a remainder of 390.
The number 5 becomes the next digit in our result. 
Result so far: 50574.835
If we subtract 3830 from 4220, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 12:
766 can be fit into 3900 5 times, resulting in a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 50574.8355
Subtracting 3830 from 3900 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 50574.8355 and a remainder of 0.0007.
