879141 ÷ 2 
We want to figure out the number of times 879141 can be divided by 2.

Let's proceed to step 1:
8 divided by 2 is 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.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 2

Going ahead to step 2:
When dividing 7 by 2, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Deduct 6 from 7 and we're left with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 2

Advancing to step 3:
2 can be fit into 19 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 439.0
If we subtract 18 from 19, we get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 2

Step 4:
2 can be fit into 11 5 times, resulting in a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 4395.0
The remainder is 1 after subtracting 10 from 11.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 2

Going ahead to step 5:
The number 2 fits into 14 7 times, leaving a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 43957.0
The remainder is 0 after subtracting 14 from 14.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 2

Advancing to step 6:
2 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 439570.0
Subtracting 0 from 1 leaves us 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.

Going ahead to step 7:
When dividing 10 by 2, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 439570.5
If we subtract 10 from 10, 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.

Step 8:
0 divided by 2 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 439570.5
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.

Advancing to step 9:
If we divide 0 by 2, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 439570.5
Subtracting 0 from 0 leaves us 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 439570.5, with a leftover of 0.0.
