We look at the division of 80810301 by 72 
Let's see how many times 72 fits into 80810301.

Let's proceed to step 1:
8 divided by 72 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 72

Going ahead to step 2:
72 can be fit into 80 1 times, resulting in a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 8 after subtracting 72 from 80.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 72

On to step 3:
72 goes into 88 1 times with a remainder of 16.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 72 from 88 leaves us with 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 72

Advancing to step 4:
161 divided by 72 is 2 with a remainder of 17.
The next digit of our result is 2. 
Result so far: 112.0
Subtracting 144 from 161 leaves us with 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 72

Advancing to step 5:
170 divided by 72 is 2 with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 1122.0
Subtracting 144 from 170 leaves us with 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 72

Step 6:
If we divide 263 by 72, we get 3 and a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 11223.0
The remainder is 47 after subtracting 216 from 263.
Fetch the next digit (0) from the dividend, attach it to 47 and continue: 470 / 72

Moving on to step 7:
When dividing 470 by 72, we get 6 with a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 112236.0
If we subtract 432 from 470, we get 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 72

Advancing to step 8:
The number 72 fits into 381 5 times, leaving a remainder of 21.
Put 5 as the next digit of the answer. 
Result so far: 1122365.0
The remainder is 21 after subtracting 360 from 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
When dividing 210 by 72, we get 2 with a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 1122365.2
Subtract 144 from 210 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 10:
660 divided by 72 is 9 with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 1122365.29
If we subtract 648 from 660, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
When dividing 120 by 72, we get 1 with a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 1122365.291
Deduct 72 from 120 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 12:
72 goes into 480 6 times with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 1122365.2916
If we take 432 away from 480, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 13:
The number 72 fits into 480 6 times, leaving a remainder of 48.
The next digit of our result is 6. 
Result so far: 1122365.29166
If we subtract 432 from 480, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 1122365.29166 with a remainder of 4.8e-05.
