862839 ÷ 4 
We want to figure out the number of times 862839 can be divided by 4.

Let's proceed to step 1:
4 goes into 8 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 8 from 8 leaves us with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 4

Moving on to step 2:
When dividing 6 by 4, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 21.0
The remainder is 2 after subtracting 4 from 6.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 4

Step 3:
If we divide 22 by 4, we get 5 and a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 215.0
If we subtract 20 from 22, we get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 4

Step 4:
When dividing 28 by 4, we get 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 2157.0
The remainder is 0 after subtracting 28 from 28.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 4

Going ahead to step 5:
4 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 21570.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 4

Let's proceed to step 6:
39 divided by 4 is 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 215709.0
Deduct 36 from 39 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
4 can be fit into 30 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 215709.7
If we take 28 away from 30, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 215709.75
Deduct 20 from 20 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.

Moving on to step 9:
When dividing 0 by 4, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 215709.75
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 10:
0 divided by 4 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 215709.75
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 215709.75, with a leftover of 0.0.
