866671 ÷ 76 
The aim is to understand the frequency of 76 in 866671.

Advancing to step 1:
When dividing 8 by 76, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 76

Going ahead to step 2:
76 can be fit into 86 1 times, resulting in a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 76 away from 86, we end up with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 76

Moving on to step 3:
76 goes into 106 1 times with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 30 after subtracting 76 from 106.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 76

Moving on to step 4:
When dividing 306 by 76, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 114.0
Deduct 304 from 306 and we're left with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 76

On to step 5:
The number 76 fits into 27 0 times, leaving a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 1140.0
If we take 0 away from 27, we end up with 27.
Append the next digit (1) from the dividend to 27 and continue with: 271 / 76

Going ahead to step 6:
When dividing 271 by 76, we get 3 with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 11403.0
Deduct 228 from 271 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 7:
If we divide 430 by 76, we get 5 and a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 11403.5
If we take 380 away from 430, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
The number 76 fits into 500 6 times, leaving a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 11403.56
Subtract 456 from 500 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
440 divided by 76 is 5 with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 11403.565
The remainder is 60 after subtracting 380 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
If we divide 600 by 76, we get 7 and a remainder of 68.
The number 7 becomes the next digit in our result. 
Result so far: 11403.5657
Subtracting 532 from 600 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 11:
76 goes into 680 8 times with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 11403.56578
Subtract 608 from 680 to 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.

Moving on to step 12:
76 goes into 720 9 times with a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 11403.565789
Subtracting 684 from 720 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.

Advancing to step 13:
76 goes into 360 4 times with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 11403.5657894
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.

Going ahead to step 14:
When dividing 560 by 76, we get 7 with a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 11403.56578947
Subtracting 532 from 560 leaves us 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.

Our division results in 11403.56578947 with a remaining 2.8e-08.
