We look at the division of 80105235 by 720 
We're looking to find how many times 720 goes into 80105235.

On to step 1:
720 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 720

Step 2:
When dividing 80 by 720, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Grab the next digit (1) from the dividend, add it to 80, then carry on: 801 / 720

Moving on to step 3:
When dividing 801 by 720, we get 1 with a remainder of 81.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 720 from 801 leaves us with 81.
Fetch the next digit (0) from the dividend, attach it to 81 and continue: 810 / 720

Let's proceed to step 4:
If we divide 810 by 720, we get 1 and a remainder of 90.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 720 from 810 to get 90.
Include the next digit (5) from the dividend after 90, then repeat: 905 / 720

Going ahead to step 5:
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: 111.0
If we take 720 away from 905, we end up with 185.
Include the next digit (2) from the dividend after 185, then repeat: 1852 / 720

Going ahead to step 6:
If we divide 1852 by 720, we get 2 and a remainder of 412.
Write down 2 as next digit of the result. 
Result so far: 1112.0
Subtract 1440 from 1852 to get 412.
Bring next digit (3) of the dividend behind the 412 and repeat the process: 4123 / 720

Going ahead to step 7:
720 can be fit into 4123 5 times, resulting in a remainder of 523.
Put 5 as the next digit of the answer. 
Result so far: 11125.0
If we take 3600 away from 4123, we end up with 523.
Append the next digit (5) from the dividend to 523 and continue with: 5235 / 720

Going ahead to step 8:
720 goes into 5235 7 times with a remainder of 195.
Use 7 as the next digit of our solution. 
Result so far: 111257.0
Subtract 5040 from 5235 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 9:
720 goes into 1950 2 times with a remainder of 510.
Use 2 as the next digit of our solution. 
Result so far: 111257.2
The remainder is 510 after subtracting 1440 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Moving on to step 10:
When dividing 5100 by 720, we get 7 with a remainder of 60.
Use 7 as the next digit of our solution. 
Result so far: 111257.27
Deduct 5040 from 5100 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
600 divided by 720 is 0 with a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 111257.27
Subtract 0 from 600 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 12:
720 can be fit into 6000 8 times, resulting in a remainder of 240.
The next digit of our result is 8. 
Result so far: 111257.2708
If we take 5760 away from 6000, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 13:
When dividing 2400 by 720, we get 3 with a remainder of 240.
Use 3 as the next digit of our solution. 
Result so far: 111257.27083
The remainder is 240 after subtracting 2160 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 14:
720 goes into 2400 3 times with a remainder of 240.
Record the quotient 3 as the next digit in the result. 
Result so far: 111257.270833
If we take 2160 away from 2400, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Our division results in 111257.270833 with a remaining 2.4e-05.
