88990493 divided by 720 
The aim is to understand the frequency of 720 in 88990493.

Going ahead to step 1:
720 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 720

On to step 2:
The number 720 fits into 88 0 times, leaving a remainder of 88.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 88 and we're left with 88.
Take the next digit (9) from the dividend and append it to 88, then repeat: 889 / 720

On to step 3:
720 can be fit into 889 1 times, resulting in a remainder of 169.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 169 after subtracting 720 from 889.
Bring next digit (9) of the dividend behind the 169 and repeat the process: 1699 / 720

Advancing to step 4:
720 goes into 1699 2 times with a remainder of 259.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 259 after subtracting 1440 from 1699.
Append the next digit (0) from the dividend to 259 and continue with: 2590 / 720

Going ahead to step 5:
When dividing 2590 by 720, we get 3 with a remainder of 430.
Use 3 as the next digit of our solution. 
Result so far: 123.0
Subtracting 2160 from 2590 leaves us with 430.
Append the next digit (4) from the dividend to 430 and continue with: 4304 / 720

Let's proceed to step 6:
When dividing 4304 by 720, we get 5 with a remainder of 704.
Write down 5 as next digit of the result. 
Result so far: 1235.0
The remainder is 704 after subtracting 3600 from 4304.
Append the next digit (9) from the dividend to 704 and continue with: 7049 / 720

On to step 7:
720 can be fit into 7049 9 times, resulting in a remainder of 569.
Record the quotient 9 as the next digit in the result. 
Result so far: 12359.0
If we subtract 6480 from 7049, we get 569.
Bring next digit (3) of the dividend behind the 569 and repeat the process: 5693 / 720

Let's proceed to step 8:
When dividing 5693 by 720, we get 7 with a remainder of 653.
Record the quotient 7 as the next digit in the result. 
Result so far: 123597.0
The remainder is 653 after subtracting 5040 from 5693.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

Going ahead to step 9:
The number 720 fits into 6530 9 times, leaving a remainder of 50.
The next digit of our result is 9. 
Result so far: 123597.9
Subtract 6480 from 6530 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
500 divided by 720 is 0 with a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 123597.9
If we take 0 away from 500, we end up 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.

On to step 11:
5000 divided by 720 is 6 with a remainder of 680.
Record the quotient 6 as the next digit in the result. 
Result so far: 123597.906
If we take 4320 away from 5000, we end up 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.

Going ahead to step 12:
720 can be fit into 6800 9 times, resulting in a remainder of 320.
Write down 9 as next digit of the result. 
Result so far: 123597.9069
Subtracting 6480 from 6800 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.

Going ahead to step 13:
The number 720 fits into 3200 4 times, leaving a remainder of 320.
The next digit of our result is 4. 
Result so far: 123597.90694
If we subtract 2880 from 3200, 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.

Moving on to step 14:
3200 divided by 720 is 4 with a remainder of 320.
Write down 4 as next digit of the result. 
Result so far: 123597.906944
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.

After the division, we end up with 123597.906944 and a remainder of 3.2e-05.
