839516 ÷ 4 
We want to figure out the number of times 839516 can be divided by 4.

Step 1:
If we divide 8 by 4, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 8 from 8, we get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 4

Let's proceed to step 2:
When dividing 3 by 4, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 4

Let's proceed to step 3:
The number 4 fits into 39 9 times, leaving a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 209.0
If we subtract 36 from 39, we get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 4

Step 4:
4 goes into 35 8 times with a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 2098.0
Subtracting 32 from 35 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 4

On to step 5:
The number 4 fits into 31 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 20987.0
Subtracting 28 from 31 leaves us with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 4

Going ahead to step 6:
4 goes into 36 9 times with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 209879.0
The remainder is 0 after subtracting 36 from 36.
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:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 209879.0
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.

Advancing to step 8:
4 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 209879.0
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.

Our division results in 209879.0 with a remaining 0.0.
