648511 divided by 76 
The aim is to understand the frequency of 76 in 648511.

Let's proceed to step 1:
The number 76 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 76

Moving on to step 2:
64 divided by 76 is 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Include the next digit (8) from the dividend after 64, then repeat: 648 / 76

Advancing to step 3:
76 goes into 648 8 times with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 40 after subtracting 608 from 648.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 76

Step 4:
The number 76 fits into 405 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
The remainder is 25 after subtracting 380 from 405.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 76

Moving on to step 5:
76 goes into 251 3 times with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 853.0
If we subtract 228 from 251, we get 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 76

Let's proceed to step 6:
The number 76 fits into 231 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 8533.0
Subtract 228 from 231 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
If we divide 30 by 76, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 8533.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
The number 76 fits into 300 3 times, leaving a remainder of 72.
Put 3 as the next digit of the answer. 
Result so far: 8533.03
If we subtract 228 from 300, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 9:
76 can be fit into 720 9 times, resulting in a remainder of 36.
The next digit of our result is 9. 
Result so far: 8533.039
If we subtract 684 from 720, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 10:
76 goes into 360 4 times with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 8533.0394
If we take 304 away from 360, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 11:
560 divided by 76 is 7 with a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 8533.03947
If we take 532 away from 560, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 12:
280 divided by 76 is 3 with a remainder of 52.
Use 3 as the next digit of our solution. 
Result so far: 8533.039473
Subtracting 228 from 280 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 13:
76 goes into 520 6 times with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 8533.0394736
Deduct 456 from 520 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 14:
76 goes into 640 8 times with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 8533.03947368
Subtract 608 from 640 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 8533.03947368 with a balance of 3.2e-08.
