Let's divide 90599537 by 720
The aim is to understand the frequency of 720 in 90599537.

Advancing to step 1:
720 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 720

Advancing to step 2:
If we divide 90 by 720, we get 0 and a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Include the next digit (5) from the dividend after 90, then repeat: 905 / 720

Going ahead to step 3:
When dividing 905 by 720, we get 1 with a remainder of 185.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 720 away from 905, we end up with 185.
Bring next digit (9) of the dividend behind the 185 and repeat the process: 1859 / 720

Let's proceed to step 4:
720 can be fit into 1859 2 times, resulting in a remainder of 419.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 419 after subtracting 1440 from 1859.
Fetch the next digit (9) from the dividend, attach it to 419 and continue: 4199 / 720

Let's proceed to step 5:
4199 divided by 720 is 5 with a remainder of 599.
The next digit of our result is 5. 
Result so far: 125.0
If we subtract 3600 from 4199, we get 599.
Include the next digit (5) from the dividend after 599, then repeat: 5995 / 720

On to step 6:
If we divide 5995 by 720, we get 8 and a remainder of 235.
Use 8 as the next digit of our solution. 
Result so far: 1258.0
The remainder is 235 after subtracting 5760 from 5995.
Include the next digit (3) from the dividend after 235, then repeat: 2353 / 720

Advancing to step 7:
The number 720 fits into 2353 3 times, leaving a remainder of 193.
Put 3 as the next digit of the answer. 
Result so far: 12583.0
The remainder is 193 after subtracting 2160 from 2353.
Bring next digit (7) of the dividend behind the 193 and repeat the process: 1937 / 720

Let's proceed to step 8:
The number 720 fits into 1937 2 times, leaving a remainder of 497.
The next digit of our result is 2. 
Result so far: 125832.0
The remainder is 497 after subtracting 1440 from 1937.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Step 9:
720 goes into 4970 6 times with a remainder of 650.
The number 6 becomes the next digit in our result. 
Result so far: 125832.6
Subtract 4320 from 4970 to get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

On to step 10:
The number 720 fits into 6500 9 times, leaving a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 125832.69
Subtract 6480 from 6500 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
When dividing 200 by 720, we get 0 with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 125832.69
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 12:
720 can be fit into 2000 2 times, resulting in a remainder of 560.
Write down 2 as next digit of the result. 
Result so far: 125832.6902
Subtract 1440 from 2000 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 13:
720 goes into 5600 7 times with a remainder of 560.
Put 7 as the next digit of the answer. 
Result so far: 125832.69027
Subtracting 5040 from 5600 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 14:
When dividing 5600 by 720, we get 7 with a remainder of 560.
Write down 7 as next digit of the result. 
Result so far: 125832.690277
Subtracting 5040 from 5600 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

The final outcome is 125832.690277, with a leftover of 5.6e-05.
