We look at the division of 770642 by 76 
The aim is to understand the frequency of 76 in 770642.

Advancing to step 1:
If we divide 7 by 76, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 76

Advancing to step 2:
76 can be fit into 77 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 76 from 77 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 76

Step 3:
10 divided by 76 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 10 and we're left with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 76

On to step 4:
The number 76 fits into 106 1 times, leaving a remainder of 30.
The next digit of our result is 1. 
Result so far: 101.0
Subtract 76 from 106 to get 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 76

On to step 5:
The number 76 fits into 304 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 1014.0
Subtracting 304 from 304 leaves us with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 76

Moving on to step 6:
If we divide 2 by 76, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 10140.0
Subtracting 0 from 2 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
The number 76 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 10140.0
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.

On to step 8:
The number 76 fits into 200 2 times, leaving a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 10140.02
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.

Advancing to step 9:
The number 76 fits into 480 6 times, leaving a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 10140.026
The remainder is 24 after subtracting 456 from 480.
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 10:
The number 76 fits into 240 3 times, leaving a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 10140.0263
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.

Moving on to step 11:
76 can be fit into 120 1 times, resulting in a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 10140.02631
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.

Step 12:
76 can be fit into 440 5 times, resulting in a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 10140.026315
Deduct 380 from 440 and we're left 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.

Moving on to step 13:
If we divide 600 by 76, we get 7 and a remainder of 68.
Use 7 as the next digit of our solution. 
Result so far: 10140.0263157
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.

Let's proceed to step 14:
76 can be fit into 680 8 times, resulting in a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 10140.02631578
The remainder is 72 after subtracting 608 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 10140.02631578 with a remaining 7.2e-08.
