We divide 72903392 by 576
The aim is to understand the frequency of 576 in 72903392.

Going ahead to step 1:
7 divided by 576 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 576

Going ahead to step 2:
72 divided by 576 is 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Bring next digit (9) of the dividend behind the 72 and repeat the process: 729 / 576

Let's proceed to step 3:
576 can be fit into 729 1 times, resulting in a remainder of 153.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 576 from 729 and we're left with 153.
Grab the next digit (0) from the dividend, add it to 153, then carry on: 1530 / 576

Advancing to step 4:
The number 576 fits into 1530 2 times, leaving a remainder of 378.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 1152 from 1530 leaves us with 378.
Append the next digit (3) from the dividend to 378 and continue with: 3783 / 576

Going ahead to step 5:
The number 576 fits into 3783 6 times, leaving a remainder of 327.
Write down 6 as next digit of the result. 
Result so far: 126.0
Subtracting 3456 from 3783 leaves us with 327.
Take the next digit (3) from the dividend and append it to 327, then repeat: 3273 / 576

Going ahead to step 6:
If we divide 3273 by 576, we get 5 and a remainder of 393.
Write down 5 as next digit of the result. 
Result so far: 1265.0
If we take 2880 away from 3273, we end up with 393.
Bring next digit (9) of the dividend behind the 393 and repeat the process: 3939 / 576

Advancing to step 7:
576 can be fit into 3939 6 times, resulting in a remainder of 483.
Record the quotient 6 as the next digit in the result. 
Result so far: 12656.0
Subtracting 3456 from 3939 leaves us with 483.
Grab the next digit (2) from the dividend, add it to 483, then carry on: 4832 / 576

Let's proceed to step 8:
If we divide 4832 by 576, we get 8 and a remainder of 224.
Record the quotient 8 as the next digit in the result. 
Result so far: 126568.0
Subtracting 4608 from 4832 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 9:
576 can be fit into 2240 3 times, resulting in a remainder of 512.
The number 3 becomes the next digit in our result. 
Result so far: 126568.3
The remainder is 512 after subtracting 1728 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Going ahead to step 10:
If we divide 5120 by 576, we get 8 and a remainder of 512.
Put 8 as the next digit of the answer. 
Result so far: 126568.38
Subtract 4608 from 5120 to get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Step 11:
When dividing 5120 by 576, we get 8 with a remainder of 512.
Use 8 as the next digit of our solution. 
Result so far: 126568.388
Deduct 4608 from 5120 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

After the division, we end up with 126568.388 and a remainder of 0.0512.
