We're dividing 357170 by 25 
We're looking to find how many times 25 goes into 357170.

On to step 1:
When dividing 3 by 25, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 25

Advancing to step 2:
If we divide 35 by 25, we get 1 and a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 25 from 35 leaves us with 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 25

Step 3:
The number 25 fits into 107 4 times, leaving a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 100 from 107 to get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 25

On to step 4:
25 goes into 71 2 times with a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 142.0
If we subtract 50 from 71, we get 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 25

Let's proceed to step 5:
25 can be fit into 217 8 times, resulting in a remainder of 17.
Put 8 as the next digit of the answer. 
Result so far: 1428.0
Subtracting 200 from 217 leaves us with 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 25

Moving on to step 6:
If we divide 170 by 25, we get 6 and a remainder of 20.
The next digit of our result is 6. 
Result so far: 14286.0
If we subtract 150 from 170, 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.

Moving on to step 7:
200 divided by 25 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 14286.8
Subtracting 200 from 200 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.

Let's proceed to step 8:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 14286.8
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.

Step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 14286.8
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.

Our division results in 14286.8 with a remaining 0.0.
