23043638 ÷ 573 
The aim is to understand the frequency of 573 in 23043638.

Moving on to step 1:
The number 573 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 573

Let's proceed to step 2:
573 can be fit into 23 0 times, resulting in a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 573

On to step 3:
573 can be fit into 230 0 times, resulting in a remainder of 230.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 230 leaves us with 230.
Grab the next digit (4) from the dividend, add it to 230, then carry on: 2304 / 573

Moving on to step 4:
The number 573 fits into 2304 4 times, leaving a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 2292 away from 2304, we end up with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 573

Advancing to step 5:
573 goes into 123 0 times with a remainder of 123.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we subtract 0 from 123, we get 123.
Grab the next digit (6) from the dividend, add it to 123, then carry on: 1236 / 573

Advancing to step 6:
The number 573 fits into 1236 2 times, leaving a remainder of 90.
The number 2 becomes the next digit in our result. 
Result so far: 402.0
Deduct 1146 from 1236 and we're left with 90.
Fetch the next digit (3) from the dividend, attach it to 90 and continue: 903 / 573

Moving on to step 7:
If we divide 903 by 573, we get 1 and a remainder of 330.
Write down 1 as next digit of the result. 
Result so far: 4021.0
If we take 573 away from 903, we end up with 330.
Take the next digit (8) from the dividend and append it to 330, then repeat: 3308 / 573

Going ahead to step 8:
If we divide 3308 by 573, we get 5 and a remainder of 443.
Record the quotient 5 as the next digit in the result. 
Result so far: 40215.0
If we take 2865 away from 3308, we end up with 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Going ahead to step 9:
When dividing 4430 by 573, we get 7 with a remainder of 419.
Write down 7 as next digit of the result. 
Result so far: 40215.7
The remainder is 419 after subtracting 4011 from 4430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Step 10:
The number 573 fits into 4190 7 times, leaving a remainder of 179.
The next digit of our result is 7. 
Result so far: 40215.77
If we subtract 4011 from 4190, we get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

The quotient of the division is 40215.77, and the remainder is 0.179.
