We look at the division of 170344 by 80 
Let's see how many times 80 fits into 170344.

Step 1:
1 divided by 80 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 80

Advancing to step 2:
The number 80 fits into 17 0 times, leaving a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 80

Advancing to step 3:
80 can be fit into 170 2 times, resulting in a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 10 after subtracting 160 from 170.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 80

Let's proceed to step 4:
80 goes into 103 1 times with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 80 from 103, we get 23.
Fetch the next digit (4) from the dividend, attach it to 23 and continue: 234 / 80

Let's proceed to step 5:
When dividing 234 by 80, we get 2 with a remainder of 74.
Use 2 as the next digit of our solution. 
Result so far: 212.0
If we subtract 160 from 234, we get 74.
Bring next digit (4) of the dividend behind the 74 and repeat the process: 744 / 80

On to step 6:
When dividing 744 by 80, we get 9 with a remainder of 24.
The next digit of our result is 9. 
Result so far: 2129.0
Subtracting 720 from 744 leaves us 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:
When dividing 240 by 80, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 2129.3
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:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 2129.3
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.

Step 9:
When dividing 0 by 80, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2129.3
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.

Our division results in 2129.3 with a remaining 0.0.
