75775910 divided by 768 
The aim is to understand the frequency of 768 in 75775910.

Going ahead to step 1:
When dividing 7 by 768, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 768

Advancing to step 2:
If we divide 75 by 768, we get 0 and a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Take the next digit (7) from the dividend and append it to 75, then repeat: 757 / 768

Let's proceed to step 3:
The number 768 fits into 757 0 times, leaving a remainder of 757.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 757, we get 757.
Include the next digit (7) from the dividend after 757, then repeat: 7577 / 768

Moving on to step 4:
If we divide 7577 by 768, we get 9 and a remainder of 665.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 665 after subtracting 6912 from 7577.
Take the next digit (5) from the dividend and append it to 665, then repeat: 6655 / 768

Let's proceed to step 5:
768 can be fit into 6655 8 times, resulting in a remainder of 511.
Put 8 as the next digit of the answer. 
Result so far: 98.0
The remainder is 511 after subtracting 6144 from 6655.
Fetch the next digit (9) from the dividend, attach it to 511 and continue: 5119 / 768

Step 6:
If we divide 5119 by 768, we get 6 and a remainder of 511.
Write down 6 as next digit of the result. 
Result so far: 986.0
If we subtract 4608 from 5119, we get 511.
Take the next digit (1) from the dividend and append it to 511, then repeat: 5111 / 768

Going ahead to step 7:
If we divide 5111 by 768, we get 6 and a remainder of 503.
Put 6 as the next digit of the answer. 
Result so far: 9866.0
If we take 4608 away from 5111, we end up with 503.
Take the next digit (0) from the dividend and append it to 503, then repeat: 5030 / 768

Step 8:
768 goes into 5030 6 times with a remainder of 422.
Use 6 as the next digit of our solution. 
Result so far: 98666.0
If we subtract 4608 from 5030, we get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Going ahead to step 9:
4220 divided by 768 is 5 with a remainder of 380.
Use 5 as the next digit of our solution. 
Result so far: 98666.5
The remainder is 380 after subtracting 3840 from 4220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 10:
The number 768 fits into 3800 4 times, leaving a remainder of 728.
Use 4 as the next digit of our solution. 
Result so far: 98666.54
Subtracting 3072 from 3800 leaves us with 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Step 11:
768 goes into 7280 9 times with a remainder of 368.
Record the quotient 9 as the next digit in the result. 
Result so far: 98666.549
If we subtract 6912 from 7280, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 12:
3680 divided by 768 is 4 with a remainder of 608.
Put 4 as the next digit of the answer. 
Result so far: 98666.5494
Deduct 3072 from 3680 and we're left with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

On to step 13:
6080 divided by 768 is 7 with a remainder of 704.
The number 7 becomes the next digit in our result. 
Result so far: 98666.54947
The remainder is 704 after subtracting 5376 from 6080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Let's proceed to step 14:
The number 768 fits into 7040 9 times, leaving a remainder of 128.
The number 9 becomes the next digit in our result. 
Result so far: 98666.549479
Subtract 6912 from 7040 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 15:
768 goes into 1280 1 times with a remainder of 512.
Record the quotient 1 as the next digit in the result. 
Result so far: 98666.5494791
If we subtract 768 from 1280, we get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Let's proceed to step 16:
768 goes into 5120 6 times with a remainder of 512.
The next digit of our result is 6. 
Result so far: 98666.54947916
Subtract 4608 from 5120 to get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

The quotient of the division is 98666.54947916, and the remainder is 5.12e-07.
