854109 divided by 2 
We want to figure out the number of times 854109 can be divided by 2.

Advancing to step 1:
When dividing 8 by 2, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 8 away from 8, we end up with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 2

Let's proceed to step 2:
When dividing 5 by 2, we get 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we take 4 away from 5, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 2

Going ahead to step 3:
14 divided by 2 is 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 427.0
If we subtract 14 from 14, we get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 2

Advancing to step 4:
2 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 4270.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 2

Step 5:
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: 42705.0
If we take 10 away from 10, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 2

Going ahead to step 6:
9 divided by 2 is 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 427054.0
Deduct 8 from 9 and we're left 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.

Advancing to step 7:
When dividing 10 by 2, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 427054.5
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.

Advancing to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 427054.5
Subtract 0 from 0 to 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.

Step 9:
0 divided by 2 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 427054.5
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 quotient of the division is 427054.5, and the remainder is 0.0.
