We divide 251226 by 2
We're looking to find how many times 2 goes into 251226.

On to step 1:
2 goes into 2 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 2 from 2 and we're left with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 2

On to step 2:
2 can be fit into 5 2 times, resulting in a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 1 after subtracting 4 from 5.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 2

Going ahead to step 3:
2 goes into 11 5 times with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 125.0
If we subtract 10 from 11, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 2

Step 4:
The number 2 fits into 12 6 times, leaving a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 1256.0
If we subtract 12 from 12, we get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 2

On to step 5:
When dividing 2 by 2, we get 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 12561.0
If we take 2 away from 2, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 2

Advancing to step 6:
The number 2 fits into 6 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 125613.0
Deduct 6 from 6 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.

Advancing to step 7:
If we divide 0 by 2, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 125613.0
The remainder is 0 after subtracting 0 from 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:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 125613.0
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.

The final result is 125613.0 with a remainder of 0.0.
