7573257 divided by 764 
The aim is to understand the frequency of 764 in 7573257.

Step 1:
764 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 764

Advancing to step 2:
75 divided by 764 is 0 with a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Include the next digit (7) from the dividend after 75, then repeat: 757 / 764

Going ahead to step 3:
764 goes into 757 0 times with a remainder of 757.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 757, we get 757.
Grab the next digit (3) from the dividend, add it to 757, then carry on: 7573 / 764

Going ahead to step 4:
If we divide 7573 by 764, we get 9 and a remainder of 697.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 6876 from 7573 and we're left with 697.
Bring next digit (2) of the dividend behind the 697 and repeat the process: 6972 / 764

Step 5:
If we divide 6972 by 764, we get 9 and a remainder of 96.
Use 9 as the next digit of our solution. 
Result so far: 99.0
The remainder is 96 after subtracting 6876 from 6972.
Append the next digit (5) from the dividend to 96 and continue with: 965 / 764

Advancing to step 6:
If we divide 965 by 764, we get 1 and a remainder of 201.
Use 1 as the next digit of our solution. 
Result so far: 991.0
Deduct 764 from 965 and we're left with 201.
Take the next digit (7) from the dividend and append it to 201, then repeat: 2017 / 764

Moving on to step 7:
If we divide 2017 by 764, we get 2 and a remainder of 489.
Put 2 as the next digit of the answer. 
Result so far: 9912.0
The remainder is 489 after subtracting 1528 from 2017.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Advancing to step 8:
764 goes into 4890 6 times with a remainder of 306.
The number 6 becomes the next digit in our result. 
Result so far: 9912.6
Subtracting 4584 from 4890 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Moving on to step 9:
764 can be fit into 3060 4 times, resulting in a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 9912.64
Deduct 3056 from 3060 and we're left 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.

Going ahead to step 10:
When dividing 40 by 764, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 9912.64
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.

Moving on to step 11:
If we divide 400 by 764, we get 0 and a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 9912.64
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

In conclusion, the division gives 9912.64 with a balance of 0.004.
