We look at the division of 36438560 by 576 
The aim is to understand the frequency of 576 in 36438560.

Advancing to step 1:
When dividing 3 by 576, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 576

Advancing to step 2:
576 goes into 36 0 times with a remainder of 36.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 36 to get 36.
Append the next digit (4) from the dividend to 36 and continue with: 364 / 576

Step 3:
The number 576 fits into 364 0 times, leaving a remainder of 364.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 364 leaves us with 364.
Take the next digit (3) from the dividend and append it to 364, then repeat: 3643 / 576

On to step 4:
3643 divided by 576 is 6 with a remainder of 187.
The next digit of our result is 6. 
Result so far: 6.0
If we take 3456 away from 3643, we end up with 187.
Bring next digit (8) of the dividend behind the 187 and repeat the process: 1878 / 576

Let's proceed to step 5:
1878 divided by 576 is 3 with a remainder of 150.
Use 3 as the next digit of our solution. 
Result so far: 63.0
If we subtract 1728 from 1878, we get 150.
Grab the next digit (5) from the dividend, add it to 150, then carry on: 1505 / 576

Advancing to step 6:
When dividing 1505 by 576, we get 2 with a remainder of 353.
Write down 2 as next digit of the result. 
Result so far: 632.0
The remainder is 353 after subtracting 1152 from 1505.
Take the next digit (6) from the dividend and append it to 353, then repeat: 3536 / 576

Going ahead to step 7:
When dividing 3536 by 576, we get 6 with a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 6326.0
If we subtract 3456 from 3536, we get 80.
Bring next digit (0) of the dividend behind the 80 and repeat the process: 800 / 576

On to step 8:
When dividing 800 by 576, we get 1 with a remainder of 224.
The next digit of our result is 1. 
Result so far: 63261.0
Subtracting 576 from 800 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:
When dividing 2240 by 576, we get 3 with a remainder of 512.
Write down 3 as next digit of the result. 
Result so far: 63261.3
If we subtract 1728 from 2240, we 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.

Going ahead to step 10:
If we divide 5120 by 576, we get 8 and a remainder of 512.
The next digit of our result is 8. 
Result so far: 63261.38
If we take 4608 away from 5120, we end up 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.

Moving on to step 11:
The number 576 fits into 5120 8 times, leaving a remainder of 512.
The number 8 becomes the next digit in our result. 
Result so far: 63261.388
If we subtract 4608 from 5120, we 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.

The quotient of the division is 63261.388, and the remainder is 0.0512.
