Let's divide 71986850 by 768
The aim is to understand the frequency of 768 in 71986850.

Advancing to step 1:
When dividing 7 by 768, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 768

Moving on to step 2:
The number 768 fits into 71 0 times, leaving a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Append the next digit (9) from the dividend to 71 and continue with: 719 / 768

Let's proceed to step 3:
The number 768 fits into 719 0 times, leaving a remainder of 719.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 719, we end up with 719.
Include the next digit (8) from the dividend after 719, then repeat: 7198 / 768

Moving on to step 4:
The number 768 fits into 7198 9 times, leaving a remainder of 286.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 6912 away from 7198, we end up with 286.
Grab the next digit (6) from the dividend, add it to 286, then carry on: 2866 / 768

Let's proceed to step 5:
If we divide 2866 by 768, we get 3 and a remainder of 562.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
Subtract 2304 from 2866 to get 562.
Fetch the next digit (8) from the dividend, attach it to 562 and continue: 5628 / 768

Moving on to step 6:
The number 768 fits into 5628 7 times, leaving a remainder of 252.
The next digit of our result is 7. 
Result so far: 937.0
If we take 5376 away from 5628, we end up with 252.
Bring next digit (5) of the dividend behind the 252 and repeat the process: 2525 / 768

Moving on to step 7:
The number 768 fits into 2525 3 times, leaving a remainder of 221.
Write down 3 as next digit of the result. 
Result so far: 9373.0
If we take 2304 away from 2525, we end up with 221.
Include the next digit (0) from the dividend after 221, then repeat: 2210 / 768

Going ahead to step 8:
768 goes into 2210 2 times with a remainder of 674.
Record the quotient 2 as the next digit in the result. 
Result so far: 93732.0
Deduct 1536 from 2210 and we're left with 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

Step 9:
6740 divided by 768 is 8 with a remainder of 596.
Write down 8 as next digit of the result. 
Result so far: 93732.8
Subtract 6144 from 6740 to get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Moving on to step 10:
When dividing 5960 by 768, we get 7 with a remainder of 584.
The number 7 becomes the next digit in our result. 
Result so far: 93732.87
The remainder is 584 after subtracting 5376 from 5960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Moving on to step 11:
The number 768 fits into 5840 7 times, leaving a remainder of 464.
Put 7 as the next digit of the answer. 
Result so far: 93732.877
Deduct 5376 from 5840 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

The final result is 93732.877 with a remainder of 0.0464.
