We're dividing 172836 by 6 
We want to figure out the number of times 172836 can be divided by 6.

Going ahead to step 1:
6 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 6

Moving on to step 2:
When dividing 17 by 6, we get 2 with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 12 from 17, we get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 6

Going ahead to step 3:
6 can be fit into 52 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we take 48 away from 52, we end up with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 6

Going ahead to step 4:
48 divided by 6 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 288.0
Subtracting 48 from 48 leaves us with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 6

Let's proceed to step 5:
The number 6 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 2880.0
Subtract 0 from 3 to get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 6

Step 6:
When dividing 36 by 6, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 28806.0
Deduct 36 from 36 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 7:
The number 6 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 28806.0
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.

Step 8:
The number 6 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 28806.0
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.

Our division results in 28806.0 with a remaining 0.0.
