We look at the division of 842191 by 2 
Let's see how many times 2 fits into 842191.

Moving on to step 1:
2 can be fit into 8 4 times, resulting in a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 8 from 8 to get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 2

Advancing to step 2:
4 divided by 2 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Subtract 4 from 4 to get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 2

Step 3:
2 can be fit into 2 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 421.0
Deduct 2 from 2 and we're left with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 2

Step 4:
2 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 4210.0
If we subtract 0 from 1, we get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 2

Going ahead to step 5:
19 divided by 2 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 42109.0
The remainder is 1 after subtracting 18 from 19.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 2

Step 6:
If we divide 11 by 2, we get 5 and a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 421095.0
If we subtract 10 from 11, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
10 divided by 2 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 421095.5
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:
0 divided by 2 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 421095.5
If we take 0 away from 0, 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.

Step 9:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 421095.5
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.

In conclusion, the division gives 421095.5 with a balance of 0.0.
