We look at the division of 203406 by 80 
We want to divide 203406 by 80.

Let's proceed to step 1:
When dividing 2 by 80, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 80

On to step 2:
80 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 80

Let's proceed to step 3:
80 can be fit into 203 2 times, resulting in a remainder of 43.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 160 from 203 and we're left with 43.
Include the next digit (4) from the dividend after 43, then repeat: 434 / 80

Advancing to step 4:
80 can be fit into 434 5 times, resulting in a remainder of 34.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 400 from 434 and we're left with 34.
Bring next digit (0) of the dividend behind the 34 and repeat the process: 340 / 80

Going ahead to step 5:
When dividing 340 by 80, we get 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 254.0
If we take 320 away from 340, we end up with 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 80

Advancing to step 6:
80 can be fit into 206 2 times, resulting in a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 2542.0
Deduct 160 from 206 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 7:
80 goes into 460 5 times with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 2542.5
Subtract 400 from 460 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
80 goes into 600 7 times with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 2542.57
Subtracting 560 from 600 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
If we divide 400 by 80, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 2542.575
If we subtract 400 from 400, we 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.

On to step 10:
80 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2542.575
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.

Moving on to step 11:
80 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2542.575
Subtracting 0 from 0 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.

The quotient of the division is 2542.575, and the remainder is 0.0.
