We're dividing 172836 by 25 
Our goal is to divide 172836 by 25.

On to step 1:
1 divided by 25 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 25

Let's proceed to step 2:
25 can be fit into 17 0 times, resulting in a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 25

Let's proceed to step 3:
25 goes into 172 6 times with a remainder of 22.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 22 after subtracting 150 from 172.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 25

Step 4:
228 divided by 25 is 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 69.0
Deduct 225 from 228 and we're left with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 25

Moving on to step 5:
25 can be fit into 33 1 times, resulting in a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 691.0
Subtracting 25 from 33 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 25

Step 6:
If we divide 86 by 25, we get 3 and a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 6913.0
If we subtract 75 from 86, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
25 goes into 110 4 times with a remainder of 10.
The next digit of our result is 4. 
Result so far: 6913.4
Subtracting 100 from 110 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
25 can be fit into 100 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 6913.44
Deduct 100 from 100 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.

The final result is 6913.44 with a remainder of 0.0.
