We're dividing 853810 by 2 
We want to figure out the number of times 853810 can be divided by 2.

Going ahead to step 1:
2 can be fit into 8 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 0 after subtracting 8 from 8.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 2

Advancing to step 2:
2 can be fit into 5 2 times, resulting in a remainder of 1.
The next digit of our result is 2. 
Result so far: 42.0
If we subtract 4 from 5, we get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 2

Let's proceed to step 3:
13 divided by 2 is 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 426.0
If we subtract 12 from 13, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 2

Step 4:
If we divide 18 by 2, we get 9 and a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 4269.0
The remainder is 0 after subtracting 18 from 18.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

Going ahead to step 5:
If we divide 1 by 2, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 42690.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 2

Moving on to step 6:
If we divide 10 by 2, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 426905.0
The remainder is 0 after subtracting 10 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
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: 426905.0
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.

Step 8:
2 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 426905.0
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.

The final outcome is 426905.0, with a leftover of 0.0.
