Let's divide 20577009 by 720
The aim is to understand the frequency of 720 in 20577009.

Step 1:
2 divided by 720 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 720

Step 2:
20 divided by 720 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 720

Step 3:
When dividing 205 by 720, we get 0 with a remainder of 205.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 205 leaves us with 205.
Take the next digit (7) from the dividend and append it to 205, then repeat: 2057 / 720

Going ahead to step 4:
720 goes into 2057 2 times with a remainder of 617.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1440 from 2057 to get 617.
Bring next digit (7) of the dividend behind the 617 and repeat the process: 6177 / 720

On to step 5:
6177 divided by 720 is 8 with a remainder of 417.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we subtract 5760 from 6177, we get 417.
Append the next digit (0) from the dividend to 417 and continue with: 4170 / 720

On to step 6:
When dividing 4170 by 720, we get 5 with a remainder of 570.
Put 5 as the next digit of the answer. 
Result so far: 285.0
Deduct 3600 from 4170 and we're left with 570.
Take the next digit (0) from the dividend and append it to 570, then repeat: 5700 / 720

Going ahead to step 7:
The number 720 fits into 5700 7 times, leaving a remainder of 660.
Write down 7 as next digit of the result. 
Result so far: 2857.0
Subtract 5040 from 5700 to get 660.
Append the next digit (9) from the dividend to 660 and continue with: 6609 / 720

Let's proceed to step 8:
6609 divided by 720 is 9 with a remainder of 129.
The next digit of our result is 9. 
Result so far: 28579.0
If we take 6480 away from 6609, we end up with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Let's proceed to step 9:
If we divide 1290 by 720, we get 1 and a remainder of 570.
Write down 1 as next digit of the result. 
Result so far: 28579.1
Subtract 720 from 1290 to get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Let's proceed to step 10:
When dividing 5700 by 720, we get 7 with a remainder of 660.
The next digit of our result is 7. 
Result so far: 28579.17
Subtract 5040 from 5700 to get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Step 11:
When dividing 6600 by 720, we get 9 with a remainder of 120.
The number 9 becomes the next digit in our result. 
Result so far: 28579.179
If we subtract 6480 from 6600, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 12:
The number 720 fits into 1200 1 times, leaving a remainder of 480.
The number 1 becomes the next digit in our result. 
Result so far: 28579.1791
Subtract 720 from 1200 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 13:
4800 divided by 720 is 6 with a remainder of 480.
Use 6 as the next digit of our solution. 
Result so far: 28579.17916
If we take 4320 away from 4800, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 14:
4800 divided by 720 is 6 with a remainder of 480.
The next digit of our result is 6. 
Result so far: 28579.179166
The remainder is 480 after subtracting 4320 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

After the division, we end up with 28579.179166 and a remainder of 4.8e-05.
