53281589 ÷ 720 
The aim is to understand the frequency of 720 in 53281589.

Let's proceed to step 1:
5 divided by 720 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 720

Let's proceed to step 2:
The number 720 fits into 53 0 times, leaving a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Include the next digit (2) from the dividend after 53, then repeat: 532 / 720

On to step 3:
The number 720 fits into 532 0 times, leaving a remainder of 532.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 532, we get 532.
Append the next digit (8) from the dividend to 532 and continue with: 5328 / 720

Going ahead to step 4:
720 can be fit into 5328 7 times, resulting in a remainder of 288.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 288 after subtracting 5040 from 5328.
Take the next digit (1) from the dividend and append it to 288, then repeat: 2881 / 720

Step 5:
2881 divided by 720 is 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 74.0
Deduct 2880 from 2881 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 720

On to step 6:
If we divide 15 by 720, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 740.0
The remainder is 15 after subtracting 0 from 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 720

Moving on to step 7:
If we divide 158 by 720, we get 0 and a remainder of 158.
The number 0 becomes the next digit in our result. 
Result so far: 7400.0
The remainder is 158 after subtracting 0 from 158.
Bring next digit (9) of the dividend behind the 158 and repeat the process: 1589 / 720

Moving on to step 8:
720 goes into 1589 2 times with a remainder of 149.
Record the quotient 2 as the next digit in the result. 
Result so far: 74002.0
The remainder is 149 after subtracting 1440 from 1589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Let's proceed to step 9:
The number 720 fits into 1490 2 times, leaving a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 74002.2
If we take 1440 away from 1490, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
When dividing 500 by 720, we get 0 with a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 74002.2
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 11:
720 can be fit into 5000 6 times, resulting in a remainder of 680.
Use 6 as the next digit of our solution. 
Result so far: 74002.206
Subtracting 4320 from 5000 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Advancing to step 12:
When dividing 6800 by 720, we get 9 with a remainder of 320.
Put 9 as the next digit of the answer. 
Result so far: 74002.2069
If we subtract 6480 from 6800, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 13:
3200 divided by 720 is 4 with a remainder of 320.
The number 4 becomes the next digit in our result. 
Result so far: 74002.20694
Subtracting 2880 from 3200 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 14:
720 goes into 3200 4 times with a remainder of 320.
Use 4 as the next digit of our solution. 
Result so far: 74002.206944
Deduct 2880 from 3200 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final outcome is 74002.206944, with a leftover of 3.2e-05.
