77110910 divided by 766 
The aim is to understand the frequency of 766 in 77110910.

Let's proceed to step 1:
If we divide 7 by 766, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 766

Advancing to step 2:
766 can be fit into 77 0 times, resulting in a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Append the next digit (1) from the dividend to 77 and continue with: 771 / 766

Going ahead to step 3:
When dividing 771 by 766, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 5 after subtracting 766 from 771.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 766

Going ahead to step 4:
When dividing 51 by 766, we get 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 51 after subtracting 0 from 51.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 766

Moving on to step 5:
510 divided by 766 is 0 with a remainder of 510.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
The remainder is 510 after subtracting 0 from 510.
Include the next digit (9) from the dividend after 510, then repeat: 5109 / 766

Moving on to step 6:
766 goes into 5109 6 times with a remainder of 513.
Use 6 as the next digit of our solution. 
Result so far: 1006.0
Subtract 4596 from 5109 to get 513.
Grab the next digit (1) from the dividend, add it to 513, then carry on: 5131 / 766

Advancing to step 7:
766 goes into 5131 6 times with a remainder of 535.
Use 6 as the next digit of our solution. 
Result so far: 10066.0
If we take 4596 away from 5131, we end up with 535.
Fetch the next digit (0) from the dividend, attach it to 535 and continue: 5350 / 766

Moving on to step 8:
766 goes into 5350 6 times with a remainder of 754.
The number 6 becomes the next digit in our result. 
Result so far: 100666.0
Deduct 4596 from 5350 and we're left with 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Let's proceed to step 9:
When dividing 7540 by 766, we get 9 with a remainder of 646.
The next digit of our result is 9. 
Result so far: 100666.9
Deduct 6894 from 7540 and we're left with 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Moving on to step 10:
6460 divided by 766 is 8 with a remainder of 332.
Write down 8 as next digit of the result. 
Result so far: 100666.98
Deduct 6128 from 6460 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Moving on to step 11:
3320 divided by 766 is 4 with a remainder of 256.
Record the quotient 4 as the next digit in the result. 
Result so far: 100666.984
Deduct 3064 from 3320 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 12:
If we divide 2560 by 766, we get 3 and a remainder of 262.
Put 3 as the next digit of the answer. 
Result so far: 100666.9843
If we take 2298 away from 2560, we end up with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

On to step 13:
766 goes into 2620 3 times with a remainder of 322.
Use 3 as the next digit of our solution. 
Result so far: 100666.98433
Subtracting 2298 from 2620 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

The final result is 100666.98433 with a remainder of 0.000322.
