We're dividing 903864 by 4 
We want to divide 903864 by 4.

On to step 1:
9 divided by 4 is 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 8 from 9 to get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 4

Moving on to step 2:
4 goes into 10 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we take 8 away from 10, we end up with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 4

On to step 3:
If we divide 23 by 4, we get 5 and a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 225.0
Deduct 20 from 23 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 4

Step 4:
4 goes into 38 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 2259.0
Subtracting 36 from 38 leaves us with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 4

Moving on to step 5:
26 divided by 4 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 22596.0
Subtracting 24 from 26 leaves us with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 4

Step 6:
When dividing 24 by 4, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 225966.0
If we take 24 away from 24, 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.

On to step 7:
If we divide 0 by 4, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 225966.0
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.

Let's proceed to step 8:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 225966.0
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 outcome is 225966.0, with a leftover of 0.0.
