We look at the division of 623709 by 76 
The aim is to understand the frequency of 76 in 623709.

Moving on to step 1:
76 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 76

Step 2:
76 goes into 62 0 times with a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Fetch the next digit (3) from the dividend, attach it to 62 and continue: 623 / 76

Going ahead to step 3:
623 divided by 76 is 8 with a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 608 from 623 leaves us with 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 76

Moving on to step 4:
76 goes into 157 2 times with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 82.0
Subtract 152 from 157 to get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 76

Moving on to step 5:
50 divided by 76 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 820.0
If we subtract 0 from 50, we get 50.
Take the next digit (9) from the dividend and append it to 50, then repeat: 509 / 76

Step 6:
When dividing 509 by 76, we get 6 with a remainder of 53.
The next digit of our result is 6. 
Result so far: 8206.0
If we take 456 away from 509, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 7:
76 can be fit into 530 6 times, resulting in a remainder of 74.
The next digit of our result is 6. 
Result so far: 8206.6
If we take 456 away from 530, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 8:
The number 76 fits into 740 9 times, leaving a remainder of 56.
The number 9 becomes the next digit in our result. 
Result so far: 8206.69
Subtracting 684 from 740 leaves us 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.

Advancing to step 9:
When dividing 560 by 76, we get 7 with a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 8206.697
Deduct 532 from 560 and we're left 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.

Going ahead to step 10:
When dividing 280 by 76, we get 3 with a remainder of 52.
Write down 3 as next digit of the result. 
Result so far: 8206.6973
The remainder is 52 after subtracting 228 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 11:
The number 76 fits into 520 6 times, leaving a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 8206.69736
If we take 456 away from 520, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 12:
76 can be fit into 640 8 times, resulting in a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 8206.697368
Deduct 608 from 640 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
The number 76 fits into 320 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 8206.6973684
Subtracting 304 from 320 leaves us 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.

Step 14:
160 divided by 76 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 8206.69736842
Deduct 152 from 160 and we're left 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.

After the division, we end up with 8206.69736842 and a remainder of 8e-09.
