We look at the division of 572315 by 76 
The aim is to understand the frequency of 76 in 572315.

Advancing to step 1:
76 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 76

Step 2:
76 can be fit into 57 0 times, resulting in a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Bring next digit (2) of the dividend behind the 57 and repeat the process: 572 / 76

Advancing to step 3:
76 can be fit into 572 7 times, resulting in a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 40 after subtracting 532 from 572.
Bring next digit (3) of the dividend behind the 40 and repeat the process: 403 / 76

Step 4:
76 can be fit into 403 5 times, resulting in a remainder of 23.
Put 5 as the next digit of the answer. 
Result so far: 75.0
The remainder is 23 after subtracting 380 from 403.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 76

Let's proceed to step 5:
The number 76 fits into 231 3 times, leaving a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 753.0
The remainder is 3 after subtracting 228 from 231.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 76

Let's proceed to step 6:
If we divide 35 by 76, we get 0 and a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 7530.0
If we take 0 away from 35, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
76 can be fit into 350 4 times, resulting in a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 7530.4
The remainder is 46 after subtracting 304 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 8:
460 divided by 76 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 7530.46
If we take 456 away from 460, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
40 divided by 76 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 7530.46
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
If we divide 400 by 76, we get 5 and a remainder of 20.
The next digit of our result is 5. 
Result so far: 7530.4605
Subtracting 380 from 400 leaves us 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.

Let's proceed to step 11:
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: 7530.46052
The remainder is 48 after subtracting 152 from 200.
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 12:
76 goes into 480 6 times with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 7530.460526
If we subtract 456 from 480, we get 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 13:
76 goes into 240 3 times with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 7530.4605263
Subtract 228 from 240 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
The number 76 fits into 120 1 times, leaving a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 7530.46052631
Subtract 76 from 120 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.

The final outcome is 7530.46052631, with a leftover of 4.4e-08.
