We look at the division of 909578 by 4 
We want to figure out the number of times 909578 can be divided by 4.

Advancing to step 1:
9 divided by 4 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 8 from 9 leaves us with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 4

Advancing to step 2:
10 divided by 4 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 22.0
Subtract 8 from 10 to get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 4

On to step 3:
4 goes into 29 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 227.0
If we subtract 28 from 29, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 4

On to step 4:
When dividing 15 by 4, we get 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 2273.0
If we take 12 away from 15, we end up with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 4

On to step 5:
4 goes into 37 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 22739.0
Subtracting 36 from 37 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 4

Advancing to step 6:
When dividing 18 by 4, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 227394.0
Deduct 16 from 18 and we're left 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.

Let's proceed to step 7:
4 can be fit into 20 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 227394.5
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.

Step 8:
4 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 227394.5
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.

Moving on to step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 227394.5
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.

After the division, we end up with 227394.5 and a remainder of 0.0.
