863343 ÷ 4 
We want to figure out the number of times 863343 can be divided by 4.

Let's proceed to step 1:
If we divide 8 by 4, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 8 from 8 to get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 4

Moving on to step 2:
4 goes into 6 1 times with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
The remainder is 2 after subtracting 4 from 6.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 4

Let's proceed to step 3:
23 divided by 4 is 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 215.0
Subtracting 20 from 23 leaves us with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 4

Let's proceed to step 4:
33 divided by 4 is 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 2158.0
Subtracting 32 from 33 leaves us with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 4

Going ahead to step 5:
4 goes into 14 3 times with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 21583.0
Subtract 12 from 14 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 4

On to step 6:
23 divided by 4 is 5 with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 215835.0
Subtract 20 from 23 to get 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:
The number 4 fits into 30 7 times, leaving a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 215835.7
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
The number 4 fits into 20 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 215835.75
Subtracting 20 from 20 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.

Let's proceed to step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 215835.75
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.

Advancing to step 10:
0 divided by 4 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 215835.75
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.

Our division results in 215835.75 with a remaining 0.0.
