We divide 123570 by 25
We're looking to find how many times 25 goes into 123570.

Let's proceed to step 1:
When dividing 1 by 25, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 25

Step 2:
If we divide 12 by 25, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 25

Going ahead to step 3:
When dividing 123 by 25, we get 4 with a remainder of 23.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 100 from 123 leaves us with 23.
Fetch the next digit (5) from the dividend, attach it to 23 and continue: 235 / 25

Step 4:
When dividing 235 by 25, we get 9 with a remainder of 10.
The next digit of our result is 9. 
Result so far: 49.0
If we subtract 225 from 235, we get 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 25

On to step 5:
25 goes into 107 4 times with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 494.0
If we subtract 100 from 107, we get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 25

On to step 6:
25 can be fit into 70 2 times, resulting in a remainder of 20.
The next digit of our result is 2. 
Result so far: 4942.0
Subtracting 50 from 70 leaves us 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.

On to step 7:
When dividing 200 by 25, we get 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 4942.8
The remainder is 0 after subtracting 200 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
25 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4942.8
Subtracting 0 from 0 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.

Moving on to step 9:
If we divide 0 by 25, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 4942.8
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.

Our division results in 4942.8 with a remaining 0.0.
