354345 divided by 25 
We're looking to find how many times 25 goes into 354345.

On to step 1:
25 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 25

Going ahead to step 2:
When dividing 35 by 25, we get 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 25 from 35 and we're left with 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 25

Going ahead to step 3:
The number 25 fits into 104 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 100 from 104, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 25

Going ahead to step 4:
When dividing 43 by 25, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 141.0
Deduct 25 from 43 and we're left with 18.
Fetch the next digit (4) from the dividend, attach it to 18 and continue: 184 / 25

Let's proceed to step 5:
184 divided by 25 is 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 1417.0
If we subtract 175 from 184, we get 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 25

Step 6:
When dividing 95 by 25, we get 3 with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 14173.0
Deduct 75 from 95 and we're left with 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 7:
The number 25 fits into 200 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 14173.8
If we take 200 away from 200, 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.

Advancing to step 8:
0 divided by 25 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 14173.8
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.

On to step 9:
0 divided by 25 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 14173.8
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.

The final result is 14173.8 with a remainder of 0.0.
