We look at the division of 172106 by 80 
Our goal is to divide 172106 by 80.

Going ahead to step 1:
The number 80 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 80

Going ahead to step 2:
80 goes into 17 0 times with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 80

Advancing to step 3:
If we divide 172 by 80, we get 2 and a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 160 from 172 leaves us with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 80

Let's proceed to step 4:
80 can be fit into 121 1 times, resulting in a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtracting 80 from 121 leaves us with 41.
Append the next digit (0) from the dividend to 41 and continue with: 410 / 80

Moving on to step 5:
When dividing 410 by 80, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 215.0
Subtracting 400 from 410 leaves us with 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 80

Step 6:
If we divide 106 by 80, we get 1 and a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 2151.0
If we take 80 away from 106, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 7:
When dividing 260 by 80, we get 3 with a remainder of 20.
The next digit of our result is 3. 
Result so far: 2151.3
If we subtract 240 from 260, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
80 can be fit into 200 2 times, resulting in a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 2151.32
If we take 160 away from 200, we end up 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.

Step 9:
400 divided by 80 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 2151.325
Subtracting 400 from 400 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.

Step 10:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2151.325
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:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2151.325
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.

After the division, we end up with 2151.325 and a remainder of 0.0.
