We look at the division of 668794 by 76 
The aim is to understand the frequency of 76 in 668794.

Let's proceed to step 1:
When dividing 6 by 76, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 76

Moving on to step 2:
When dividing 66 by 76, we get 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Fetch the next digit (8) from the dividend, attach it to 66 and continue: 668 / 76

Moving on to step 3:
When dividing 668 by 76, we get 8 with a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 608 from 668, we get 60.
Include the next digit (7) from the dividend after 60, then repeat: 607 / 76

Moving on to step 4:
76 goes into 607 7 times with a remainder of 75.
Write down 7 as next digit of the result. 
Result so far: 87.0
Subtract 532 from 607 to get 75.
Grab the next digit (9) from the dividend, add it to 75, then carry on: 759 / 76

On to step 5:
759 divided by 76 is 9 with a remainder of 75.
Put 9 as the next digit of the answer. 
Result so far: 879.0
If we subtract 684 from 759, we get 75.
Include the next digit (4) from the dividend after 75, then repeat: 754 / 76

Step 6:
If we divide 754 by 76, we get 9 and a remainder of 70.
The next digit of our result is 9. 
Result so far: 8799.0
The remainder is 70 after subtracting 684 from 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 7:
When dividing 700 by 76, we get 9 with a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 8799.9
If we take 684 away from 700, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
If we divide 160 by 76, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 8799.92
Subtract 152 from 160 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
If we divide 80 by 76, we get 1 and a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 8799.921
If we subtract 76 from 80, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
76 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 8799.921
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
76 goes into 400 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 8799.92105
The remainder is 20 after subtracting 380 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
76 goes into 200 2 times with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 8799.921052
If we subtract 152 from 200, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 13:
When dividing 480 by 76, we get 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 8799.9210526
Subtract 456 from 480 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
76 can be fit into 240 3 times, resulting in a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 8799.92105263
If we take 228 away from 240, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 8799.92105263 with a remaining 1.2e-08.
