647688 ÷ 76 
The aim is to understand the frequency of 76 in 647688.

Step 1:
If we divide 6 by 76, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 76

Step 2:
76 can be fit into 64 0 times, resulting in a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Append the next digit (7) from the dividend to 64 and continue with: 647 / 76

Going ahead to step 3:
647 divided by 76 is 8 with a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 39 after subtracting 608 from 647.
Include the next digit (6) from the dividend after 39, then repeat: 396 / 76

Going ahead to step 4:
The number 76 fits into 396 5 times, leaving a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 85.0
Subtracting 380 from 396 leaves us with 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 76

Let's proceed to step 5:
The number 76 fits into 168 2 times, leaving a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 852.0
Deduct 152 from 168 and we're left with 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 76

On to step 6:
The number 76 fits into 168 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 8522.0
If we take 152 away from 168, 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.

Going ahead to step 7:
160 divided by 76 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 8522.2
Subtracting 152 from 160 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
When dividing 80 by 76, we get 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 8522.21
The remainder is 4 after subtracting 76 from 80.
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 9:
40 divided by 76 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 8522.21
The remainder is 40 after subtracting 0 from 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 10:
The number 76 fits into 400 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 8522.2105
If we take 380 away from 400, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
76 can be fit into 200 2 times, resulting in a remainder of 48.
The next digit of our result is 2. 
Result so far: 8522.21052
Deduct 152 from 200 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 12:
When dividing 480 by 76, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 8522.210526
Subtracting 456 from 480 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
When dividing 240 by 76, we get 3 with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 8522.2105263
Deduct 228 from 240 and we're left 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.

Going ahead to step 14:
76 goes into 120 1 times with a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 8522.21052631
Subtracting 76 from 120 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 8522.21052631 with a remainder of 4.4e-08.
