172356 divided by 25 
Let's see how many times 25 fits into 172356.

On to step 1:
The number 25 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 25

Going ahead to step 2:
25 goes into 17 0 times with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 25

Advancing to step 3:
25 can be fit into 172 6 times, resulting in a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 150 from 172 leaves us with 22.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 25

Moving on to step 4:
25 can be fit into 223 8 times, resulting in a remainder of 23.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
The remainder is 23 after subtracting 200 from 223.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 25

On to step 5:
The number 25 fits into 235 9 times, leaving a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 689.0
If we subtract 225 from 235, we get 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 25

On to step 6:
The number 25 fits into 106 4 times, leaving a remainder of 6.
The next digit of our result is 4. 
Result so far: 6894.0
Subtract 100 from 106 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
25 goes into 60 2 times with a remainder of 10.
The next digit of our result is 2. 
Result so far: 6894.2
Subtracting 50 from 60 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.

Let's proceed to step 8:
The number 25 fits into 100 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 6894.24
If we subtract 100 from 100, 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.

Going ahead to step 9:
25 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6894.24
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.

Going ahead to step 10:
When dividing 0 by 25, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6894.24
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.

After the division, we end up with 6894.24 and a remainder of 0.0.
