270421 divided by 2 
We want to divide 270421 by 2.

Let's proceed to step 1:
2 divided by 2 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 0 after subtracting 2 from 2.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 2

Moving on to step 2:
If we divide 7 by 2, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 6 away from 7, we end up with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 2

Let's proceed to step 3:
2 goes into 10 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
Deduct 10 from 10 and we're left with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 2

Going ahead to step 4:
2 can be fit into 4 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 1352.0
If we take 4 away from 4, we end up with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 2

Advancing to step 5:
2 divided by 2 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 13521.0
If we take 2 away from 2, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 2

Let's proceed to step 6:
The number 2 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 135210.0
If we take 0 away from 1, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
10 divided by 2 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 135210.5
If we take 10 away from 10, 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 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 135210.5
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.

Going ahead to step 9:
When dividing 0 by 2, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 135210.5
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.

The final outcome is 135210.5, with a leftover of 0.0.
