20944000 ÷ 577 
The aim is to understand the frequency of 577 in 20944000.

Going ahead to step 1:
577 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 577

Moving on to step 2:
577 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 577

Moving on to step 3:
The number 577 fits into 209 0 times, leaving a remainder of 209.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 209 leaves us with 209.
Bring next digit (4) of the dividend behind the 209 and repeat the process: 2094 / 577

Let's proceed to step 4:
2094 divided by 577 is 3 with a remainder of 363.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 1731 from 2094 to get 363.
Take the next digit (4) from the dividend and append it to 363, then repeat: 3634 / 577

Moving on to step 5:
The number 577 fits into 3634 6 times, leaving a remainder of 172.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Subtracting 3462 from 3634 leaves us with 172.
Include the next digit (0) from the dividend after 172, then repeat: 1720 / 577

Going ahead to step 6:
577 can be fit into 1720 2 times, resulting in a remainder of 566.
The number 2 becomes the next digit in our result. 
Result so far: 362.0
Subtracting 1154 from 1720 leaves us with 566.
Append the next digit (0) from the dividend to 566 and continue with: 5660 / 577

Going ahead to step 7:
577 goes into 5660 9 times with a remainder of 467.
The next digit of our result is 9. 
Result so far: 3629.0
Subtracting 5193 from 5660 leaves us with 467.
Bring next digit (0) of the dividend behind the 467 and repeat the process: 4670 / 577

Advancing to step 8:
577 can be fit into 4670 8 times, resulting in a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 36298.0
If we take 4616 away from 4670, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 9:
When dividing 540 by 577, we get 0 with a remainder of 540.
Use 0 as the next digit of our solution. 
Result so far: 36298.0
The remainder is 540 after subtracting 0 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Let's proceed to step 10:
The number 577 fits into 5400 9 times, leaving a remainder of 207.
Record the quotient 9 as the next digit in the result. 
Result so far: 36298.09
If we take 5193 away from 5400, we end up with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Advancing to step 11:
577 goes into 2070 3 times with a remainder of 339.
The next digit of our result is 3. 
Result so far: 36298.093
If we subtract 1731 from 2070, we get 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

On to step 12:
When dividing 3390 by 577, we get 5 with a remainder of 505.
Put 5 as the next digit of the answer. 
Result so far: 36298.0935
If we take 2885 away from 3390, we end up with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Let's proceed to step 13:
577 goes into 5050 8 times with a remainder of 434.
Write down 8 as next digit of the result. 
Result so far: 36298.09358
If we take 4616 away from 5050, we end up with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Going ahead to step 14:
577 can be fit into 4340 7 times, resulting in a remainder of 301.
Write down 7 as next digit of the result. 
Result so far: 36298.093587
The remainder is 301 after subtracting 4039 from 4340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Moving on to step 15:
The number 577 fits into 3010 5 times, leaving a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 36298.0935875
If we take 2885 away from 3010, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 16:
If we divide 1250 by 577, we get 2 and a remainder of 96.
Write down 2 as next digit of the result. 
Result so far: 36298.09358752
Subtracting 1154 from 1250 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The final outcome is 36298.09358752, with a leftover of 9.6e-08.
