We look at the division of 120812 by 80 
Our goal is to divide 120812 by 80.

On to step 1:
1 divided by 80 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 80

Advancing to step 2:
The number 80 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 80

Let's proceed to step 3:
When dividing 120 by 80, we get 1 with a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 80 from 120 and we're left with 40.
Bring next digit (8) of the dividend behind the 40 and repeat the process: 408 / 80

Going ahead to step 4:
408 divided by 80 is 5 with a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 400 from 408 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 80

Let's proceed to step 5:
If we divide 81 by 80, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 151.0
Deduct 80 from 81 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 80

Let's proceed to step 6:
12 divided by 80 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 1510.0
Subtracting 0 from 12 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
80 can be fit into 120 1 times, resulting in a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 1510.1
If we subtract 80 from 120, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1510.15
Subtract 400 from 400 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1510.15
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1510.15
Subtract 0 from 0 to get 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 final outcome is 1510.15, with a leftover of 0.0.
