We look at the division of 80725738 by 5 
Our goal is to divide 80725738 by 5.

On to step 1:
5 goes into 8 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 5 from 8 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 5

Step 2:
5 can be fit into 30 6 times, resulting in a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 30 from 30 to get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 5

On to step 3:
5 can be fit into 7 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 161.0
If we subtract 5 from 7, we get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 5

Moving on to step 4:
5 goes into 22 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 1614.0
Subtract 20 from 22 to get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 5

Step 5:
When dividing 25 by 5, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 16145.0
Deduct 25 from 25 and we're left with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 5

On to step 6:
7 divided by 5 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 161451.0
If we take 5 away from 7, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 5

Advancing to step 7:
When dividing 23 by 5, we get 4 with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 1614514.0
Subtract 20 from 23 to get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 5

Let's proceed to step 8:
38 divided by 5 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 16145147.0
Subtracting 35 from 38 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
The number 5 fits into 30 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 16145147.6
Subtracting 30 from 30 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
The number 5 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 16145147.6
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16145147.6
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 16145147.6, and the remainder is 0.0.
