812919 divided by 76 
The aim is to understand the frequency of 76 in 812919.

Moving on to 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.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 76

On to step 2:
76 goes into 81 1 times with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 76 from 81 and we're left with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 76

On to step 3:
52 divided by 76 is 0 with a remainder of 52.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 52, we end up with 52.
Append the next digit (9) from the dividend to 52 and continue with: 529 / 76

Advancing to step 4:
76 goes into 529 6 times with a remainder of 73.
The next digit of our result is 6. 
Result so far: 106.0
Subtract 456 from 529 to get 73.
Fetch the next digit (1) from the dividend, attach it to 73 and continue: 731 / 76

Step 5:
76 can be fit into 731 9 times, resulting in a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 1069.0
Subtracting 684 from 731 leaves us with 47.
Fetch the next digit (9) from the dividend, attach it to 47 and continue: 479 / 76

Advancing to step 6:
The number 76 fits into 479 6 times, leaving a remainder of 23.
The next digit of our result is 6. 
Result so far: 10696.0
Subtract 456 from 479 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
76 can be fit into 230 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 10696.3
The remainder is 2 after subtracting 228 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
The number 76 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10696.3
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
If we divide 200 by 76, we get 2 and a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 10696.302
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.

Let's proceed to step 10:
480 divided by 76 is 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 10696.3026
If we take 456 away from 480, we end up 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.

Moving on to step 11:
The number 76 fits into 240 3 times, leaving a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 10696.30263
The remainder is 12 after subtracting 228 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
76 goes into 120 1 times with a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 10696.302631
Deduct 76 from 120 and we're left 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.

Advancing to step 13:
The number 76 fits into 440 5 times, leaving a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 10696.3026315
If we take 380 away from 440, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 14:
600 divided by 76 is 7 with a remainder of 68.
The next digit of our result is 7. 
Result so far: 10696.30263157
If we take 532 away from 600, we end up 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.

The final outcome is 10696.30263157, with a leftover of 6.8e-08.
