We look at the division of 13629412 by 576 
The aim is to understand the frequency of 576 in 13629412.

Advancing to step 1:
If we divide 1 by 576, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 576

Going ahead to step 2:
13 divided by 576 is 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 576

Going ahead to step 3:
The number 576 fits into 136 0 times, leaving a remainder of 136.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 136, we end up with 136.
Append the next digit (2) from the dividend to 136 and continue with: 1362 / 576

On to step 4:
The number 576 fits into 1362 2 times, leaving a remainder of 210.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 210 after subtracting 1152 from 1362.
Grab the next digit (9) from the dividend, add it to 210, then carry on: 2109 / 576

Moving on to step 5:
576 can be fit into 2109 3 times, resulting in a remainder of 381.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Subtracting 1728 from 2109 leaves us with 381.
Append the next digit (4) from the dividend to 381 and continue with: 3814 / 576

Moving on to step 6:
3814 divided by 576 is 6 with a remainder of 358.
Write down 6 as next digit of the result. 
Result so far: 236.0
The remainder is 358 after subtracting 3456 from 3814.
Fetch the next digit (1) from the dividend, attach it to 358 and continue: 3581 / 576

Let's proceed to step 7:
When dividing 3581 by 576, we get 6 with a remainder of 125.
Record the quotient 6 as the next digit in the result. 
Result so far: 2366.0
Subtract 3456 from 3581 to get 125.
Bring next digit (2) of the dividend behind the 125 and repeat the process: 1252 / 576

Step 8:
1252 divided by 576 is 2 with a remainder of 100.
The number 2 becomes the next digit in our result. 
Result so far: 23662.0
Subtract 1152 from 1252 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 9:
576 can be fit into 1000 1 times, resulting in a remainder of 424.
Put 1 as the next digit of the answer. 
Result so far: 23662.1
The remainder is 424 after subtracting 576 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Moving on to step 10:
4240 divided by 576 is 7 with a remainder of 208.
The next digit of our result is 7. 
Result so far: 23662.17
Subtracting 4032 from 4240 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 11:
576 can be fit into 2080 3 times, resulting in a remainder of 352.
The next digit of our result is 3. 
Result so far: 23662.173
Subtract 1728 from 2080 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.

Step 12:
3520 divided by 576 is 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 23662.1736
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.

Let's proceed to step 13:
576 goes into 640 1 times with a remainder of 64.
Put 1 as the next digit of the answer. 
Result so far: 23662.17361
If we take 576 away from 640, we end up 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.

Moving on to step 14:
640 divided by 576 is 1 with a remainder of 64.
The next digit of our result is 1. 
Result so far: 23662.173611
The remainder is 64 after subtracting 576 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 23662.173611 with a remaining 6.4e-06.
