We look at the division of 435806 by 2 
We want to divide 435806 by 2.

Step 1:
2 goes into 4 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 4 from 4, we get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 2

Going ahead to step 2:
When dividing 3 by 2, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Deduct 2 from 3 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 2

Let's proceed to step 3:
If we divide 15 by 2, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 217.0
If we take 14 away from 15, we end up with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 2

On to step 4:
18 divided by 2 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 2179.0
If we subtract 18 from 18, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 2

Let's proceed to step 5:
When dividing 0 by 2, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21790.0
Subtracting 0 from 0 leaves us with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 2

Step 6:
If we divide 6 by 2, we get 3 and a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 217903.0
The remainder is 0 after subtracting 6 from 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
If we divide 0 by 2, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 217903.0
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.

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: 217903.0
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.

The final outcome is 217903.0, with a leftover of 0.0.
