We look at the division of 172744 by 80 
Let's see how many times 80 fits into 172744.

Let's proceed to step 1:
The number 80 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 80

On to step 2:
When dividing 17 by 80, we get 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 80

Moving on to step 3:
80 goes into 172 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 160 away from 172, we end up with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 80

Advancing to step 4:
80 can be fit into 127 1 times, resulting in a remainder of 47.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Deduct 80 from 127 and we're left with 47.
Include the next digit (4) from the dividend after 47, then repeat: 474 / 80

On to step 5:
80 can be fit into 474 5 times, resulting in a remainder of 74.
Use 5 as the next digit of our solution. 
Result so far: 215.0
If we subtract 400 from 474, we get 74.
Fetch the next digit (4) from the dividend, attach it to 74 and continue: 744 / 80

Step 6:
744 divided by 80 is 9 with a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 2159.0
If we take 720 away from 744, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 7:
80 goes into 240 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 2159.3
Subtracting 240 from 240 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.

Moving on to step 8:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2159.3
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.

Advancing to step 9:
If we divide 0 by 80, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2159.3
If we subtract 0 from 0, 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.

The final outcome is 2159.3, with a leftover of 0.0.
