We look at the division of 251385 by 1 
We want to divide 251385 by 1.

Step 1:
1 can be fit into 2 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 2 from 2 to get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Let's proceed to step 2:
If we divide 5 by 1, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we subtract 5 from 5, we get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Advancing to step 3:
If we divide 1 by 1, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 251.0
If we subtract 1 from 1, we get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

On to step 4:
1 goes into 3 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 2513.0
If we subtract 3 from 3, we get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

Step 5:
8 divided by 1 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 25138.0
Subtract 8 from 8 to get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Going ahead to step 6:
When dividing 5 by 1, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 251385.0
If we take 5 away from 5, 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 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 251385.0
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.

Going ahead to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 251385.0
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.

In conclusion, the division gives 251385.0 with a balance of 0.0.
