8935388 divided by 720 
The aim is to understand the frequency of 720 in 8935388.

Going ahead to step 1:
When dividing 8 by 720, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 720

Going ahead to step 2:
The number 720 fits into 89 0 times, leaving a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Bring next digit (3) of the dividend behind the 89 and repeat the process: 893 / 720

Let's proceed to step 3:
If we divide 893 by 720, we get 1 and a remainder of 173.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 720 from 893 to get 173.
Include the next digit (5) from the dividend after 173, then repeat: 1735 / 720

On to step 4:
720 can be fit into 1735 2 times, resulting in a remainder of 295.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 1440 from 1735, we get 295.
Append the next digit (3) from the dividend to 295 and continue with: 2953 / 720

Advancing to step 5:
If we divide 2953 by 720, we get 4 and a remainder of 73.
Record the quotient 4 as the next digit in the result. 
Result so far: 124.0
Subtracting 2880 from 2953 leaves us with 73.
Grab the next digit (8) from the dividend, add it to 73, then carry on: 738 / 720

On to step 6:
720 goes into 738 1 times with a remainder of 18.
The next digit of our result is 1. 
Result so far: 1241.0
Subtracting 720 from 738 leaves us with 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 720

Let's proceed to step 7:
The number 720 fits into 188 0 times, leaving a remainder of 188.
Write down 0 as next digit of the result. 
Result so far: 12410.0
If we take 0 away from 188, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 8:
When dividing 1880 by 720, we get 2 with a remainder of 440.
The number 2 becomes the next digit in our result. 
Result so far: 12410.2
Deduct 1440 from 1880 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 9:
720 goes into 4400 6 times with a remainder of 80.
The next digit of our result is 6. 
Result so far: 12410.26
The remainder is 80 after subtracting 4320 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 10:
800 divided by 720 is 1 with a remainder of 80.
Write down 1 as next digit of the result. 
Result so far: 12410.261
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 11:
If we divide 800 by 720, we get 1 and a remainder of 80.
The number 1 becomes the next digit in our result. 
Result so far: 12410.2611
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

After the division, we end up with 12410.2611 and a remainder of 0.0008.
