864397 divided by 76 
The aim is to understand the frequency of 76 in 864397.

Step 1:
When dividing 8 by 76, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 76

Moving on to step 2:
When dividing 86 by 76, we get 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 76 from 86 to get 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 76

Step 3:
76 goes into 104 1 times with a remainder of 28.
The next digit of our result is 1. 
Result so far: 11.0
If we take 76 away from 104, we end up with 28.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 76

Step 4:
76 goes into 283 3 times with a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 113.0
The remainder is 55 after subtracting 228 from 283.
Bring next digit (9) of the dividend behind the 55 and repeat the process: 559 / 76

Let's proceed to step 5:
76 goes into 559 7 times with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 1137.0
If we take 532 away from 559, we end up with 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 76

Let's proceed to step 6:
The number 76 fits into 277 3 times, leaving a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 11373.0
Deduct 228 from 277 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
76 can be fit into 490 6 times, resulting in a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 11373.6
Deduct 456 from 490 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 8:
340 divided by 76 is 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 11373.64
Subtracting 304 from 340 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
76 can be fit into 360 4 times, resulting in a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 11373.644
Subtracting 304 from 360 leaves us 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.

In conclusion, the division gives 11373.644 with a balance of 0.0056.
