Let's divide 81628158 by 720
Our goal is to divide 81628158 by 720.

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
Subtract 0 from 8 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 720

Let's proceed to step 2:
720 can be fit into 81 0 times, resulting in a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Bring next digit (6) of the dividend behind the 81 and repeat the process: 816 / 720

On to step 3:
The number 720 fits into 816 1 times, leaving a remainder of 96.
The next digit of our result is 1. 
Result so far: 1.0
If we take 720 away from 816, we end up with 96.
Fetch the next digit (2) from the dividend, attach it to 96 and continue: 962 / 720

Going ahead to step 4:
962 divided by 720 is 1 with a remainder of 242.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 720 from 962 leaves us with 242.
Take the next digit (8) from the dividend and append it to 242, then repeat: 2428 / 720

Step 5:
If we divide 2428 by 720, we get 3 and a remainder of 268.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
If we subtract 2160 from 2428, we get 268.
Fetch the next digit (1) from the dividend, attach it to 268 and continue: 2681 / 720

Let's proceed to step 6:
The number 720 fits into 2681 3 times, leaving a remainder of 521.
Use 3 as the next digit of our solution. 
Result so far: 1133.0
If we subtract 2160 from 2681, we get 521.
Grab the next digit (5) from the dividend, add it to 521, then carry on: 5215 / 720

Advancing to step 7:
If we divide 5215 by 720, we get 7 and a remainder of 175.
Use 7 as the next digit of our solution. 
Result so far: 11337.0
Subtracting 5040 from 5215 leaves us with 175.
Take the next digit (8) from the dividend and append it to 175, then repeat: 1758 / 720

Advancing to step 8:
When dividing 1758 by 720, we get 2 with a remainder of 318.
The next digit of our result is 2. 
Result so far: 113372.0
If we take 1440 away from 1758, we end up with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Moving on to step 9:
The number 720 fits into 3180 4 times, leaving a remainder of 300.
The next digit of our result is 4. 
Result so far: 113372.4
Deduct 2880 from 3180 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 10:
The number 720 fits into 3000 4 times, leaving a remainder of 120.
Put 4 as the next digit of the answer. 
Result so far: 113372.44
If we take 2880 away from 3000, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final result is 113372.44 with a remainder of 0.12.
