We look at the division of 257069 by 1 
We want to divide 257069 by 1.

On to step 1:
The number 1 fits into 2 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 2 from 2 and we're left with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Advancing to step 2:
1 can be fit into 5 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtract 5 from 5 to get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

Moving on to step 3:
1 can be fit into 7 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 257.0
If we take 7 away from 7, we end up with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Step 4:
1 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2570.0
Subtracting 0 from 0 leaves us with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 1

On to step 5:
The number 1 fits into 6 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 25706.0
The remainder is 0 after subtracting 6 from 6.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

Step 6:
9 divided by 1 is 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 257069.0
Deduct 9 from 9 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.

On to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 257069.0
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.

Moving on to step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 257069.0
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.

After the division, we end up with 257069.0 and a remainder of 0.0.
