77490703 divided by 576 
The aim is to understand the frequency of 576 in 77490703.

Step 1:
When dividing 7 by 576, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 576

Advancing to step 2:
When dividing 77 by 576, we get 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Take the next digit (4) from the dividend and append it to 77, then repeat: 774 / 576

Step 3:
774 divided by 576 is 1 with a remainder of 198.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 576 from 774 and we're left with 198.
Take the next digit (9) from the dividend and append it to 198, then repeat: 1989 / 576

On to step 4:
576 goes into 1989 3 times with a remainder of 261.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 1728 from 1989 to get 261.
Fetch the next digit (0) from the dividend, attach it to 261 and continue: 2610 / 576

Moving on to step 5:
The number 576 fits into 2610 4 times, leaving a remainder of 306.
Put 4 as the next digit of the answer. 
Result so far: 134.0
Subtract 2304 from 2610 to get 306.
Include the next digit (7) from the dividend after 306, then repeat: 3067 / 576

Let's proceed to step 6:
When dividing 3067 by 576, we get 5 with a remainder of 187.
The next digit of our result is 5. 
Result so far: 1345.0
If we subtract 2880 from 3067, we get 187.
Include the next digit (0) from the dividend after 187, then repeat: 1870 / 576

Let's proceed to step 7:
576 goes into 1870 3 times with a remainder of 142.
The number 3 becomes the next digit in our result. 
Result so far: 13453.0
Subtract 1728 from 1870 to get 142.
Bring next digit (3) of the dividend behind the 142 and repeat the process: 1423 / 576

Moving on to step 8:
When dividing 1423 by 576, we get 2 with a remainder of 271.
Record the quotient 2 as the next digit in the result. 
Result so far: 134532.0
Deduct 1152 from 1423 and we're left with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Let's proceed to step 9:
If we divide 2710 by 576, we get 4 and a remainder of 406.
Record the quotient 4 as the next digit in the result. 
Result so far: 134532.4
Subtract 2304 from 2710 to get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Going ahead to step 10:
4060 divided by 576 is 7 with a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 134532.47
If we subtract 4032 from 4060, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
The number 576 fits into 280 0 times, leaving a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 134532.47
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 12:
When dividing 2800 by 576, we get 4 with a remainder of 496.
Use 4 as the next digit of our solution. 
Result so far: 134532.4704
If we subtract 2304 from 2800, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Let's proceed to step 13:
4960 divided by 576 is 8 with a remainder of 352.
The next digit of our result is 8. 
Result so far: 134532.47048
Subtract 4608 from 4960 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 14:
If we divide 3520 by 576, we get 6 and a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 134532.470486
Deduct 3456 from 3520 and we're left 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.

Going ahead to step 15:
640 divided by 576 is 1 with a remainder of 64.
The next digit of our result is 1. 
Result so far: 134532.4704861
Subtract 576 from 640 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 16:
640 divided by 576 is 1 with a remainder of 64.
Use 1 as the next digit of our solution. 
Result so far: 134532.47048611
Subtract 576 from 640 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 134532.47048611 and a remainder of 6.4e-08.
