We divide 879998 by 2
We want to divide 879998 by 2.

Advancing to step 1:
The number 2 fits into 8 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 8 from 8, we get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 2

Step 2:
If we divide 7 by 2, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 43.0
The remainder is 1 after subtracting 6 from 7.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 2

Let's proceed to step 3:
When dividing 19 by 2, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 439.0
Subtract 18 from 19 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 2

Moving on to step 4:
When dividing 19 by 2, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 4399.0
Subtracting 18 from 19 leaves us with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 2

Going ahead to step 5:
The number 2 fits into 19 9 times, leaving a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 43999.0
The remainder is 1 after subtracting 18 from 19.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 2

Step 6:
The number 2 fits into 18 9 times, leaving a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 439999.0
Subtracting 18 from 18 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.

Going ahead to step 7:
2 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 439999.0
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.

Step 8:
2 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 439999.0
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 439999.0, with a leftover of 0.0.
