85505815 divided by 720 
The aim is to understand the frequency of 720 in 85505815.

Moving on to step 1:
720 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 720

Moving on to step 2:
If we divide 85 by 720, we get 0 and a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Take the next digit (5) from the dividend and append it to 85, then repeat: 855 / 720

Let's proceed to step 3:
855 divided by 720 is 1 with a remainder of 135.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 720 from 855, we get 135.
Grab the next digit (0) from the dividend, add it to 135, then carry on: 1350 / 720

Going ahead to step 4:
If we divide 1350 by 720, we get 1 and a remainder of 630.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 720 away from 1350, we end up with 630.
Include the next digit (5) from the dividend after 630, then repeat: 6305 / 720

Going ahead to step 5:
The number 720 fits into 6305 8 times, leaving a remainder of 545.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
If we take 5760 away from 6305, we end up with 545.
Append the next digit (8) from the dividend to 545 and continue with: 5458 / 720

Advancing to step 6:
720 can be fit into 5458 7 times, resulting in a remainder of 418.
The number 7 becomes the next digit in our result. 
Result so far: 1187.0
Deduct 5040 from 5458 and we're left with 418.
Grab the next digit (1) from the dividend, add it to 418, then carry on: 4181 / 720

Step 7:
When dividing 4181 by 720, we get 5 with a remainder of 581.
Record the quotient 5 as the next digit in the result. 
Result so far: 11875.0
If we subtract 3600 from 4181, we get 581.
Grab the next digit (5) from the dividend, add it to 581, then carry on: 5815 / 720

On to step 8:
720 goes into 5815 8 times with a remainder of 55.
Write down 8 as next digit of the result. 
Result so far: 118758.0
Deduct 5760 from 5815 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 9:
720 can be fit into 550 0 times, resulting in a remainder of 550.
Use 0 as the next digit of our solution. 
Result so far: 118758.0
If we take 0 away from 550, we end up with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 10:
When dividing 5500 by 720, we get 7 with a remainder of 460.
Put 7 as the next digit of the answer. 
Result so far: 118758.07
Subtract 5040 from 5500 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 11:
When dividing 4600 by 720, we get 6 with a remainder of 280.
The number 6 becomes the next digit in our result. 
Result so far: 118758.076
Subtract 4320 from 4600 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 12:
The number 720 fits into 2800 3 times, leaving a remainder of 640.
Write down 3 as next digit of the result. 
Result so far: 118758.0763
If we take 2160 away from 2800, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 13:
6400 divided by 720 is 8 with a remainder of 640.
The next digit of our result is 8. 
Result so far: 118758.07638
If we subtract 5760 from 6400, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 14:
The number 720 fits into 6400 8 times, leaving a remainder of 640.
The next digit of our result is 8. 
Result so far: 118758.076388
If we take 5760 away from 6400, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

After the division, we end up with 118758.076388 and a remainder of 6.4e-05.
