We're dividing 904056 by 40 
We want to divide 904056 by 40.

On to step 1:
40 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 40

Advancing to step 2:
40 goes into 90 2 times with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 80 from 90, we get 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 40

On to step 3:
When dividing 104 by 40, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we take 80 away from 104, we end up with 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 40

Step 4:
If we divide 240 by 40, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 226.0
Subtract 240 from 240 to get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 40

Step 5:
5 divided by 40 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 2260.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 40

Step 6:
If we divide 56 by 40, we get 1 and a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 22601.0
Deduct 40 from 56 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
If we divide 160 by 40, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 22601.4
Subtracting 160 from 160 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.

Step 8:
0 divided by 40 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 22601.4
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.

Let's proceed to step 9:
0 divided by 40 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 22601.4
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.

After the division, we end up with 22601.4 and a remainder of 0.0.
