Let's divide 636280 by 4
Let's see how many times 4 fits into 636280.

Let's proceed to step 1:
When dividing 6 by 4, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 4 from 6 and we're left with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 4

Moving on to step 2:
When dividing 23 by 4, we get 5 with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 20 from 23, we get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 4

Step 3:
If we divide 36 by 4, we get 9 and a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 159.0
If we subtract 36 from 36, we get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 4

Let's proceed to step 4:
The number 4 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 1590.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 4

On to step 5:
If we divide 28 by 4, we get 7 and a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 15907.0
Subtract 28 from 28 to get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 4

Step 6:
4 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 159070.0
The remainder is 0 after subtracting 0 from 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 7:
If we divide 0 by 4, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 159070.0
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.

Let's proceed to step 8:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 159070.0
If we subtract 0 from 0, 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.

The final result is 159070.0 with a remainder of 0.0.
