We're dividing 488604 by 40 
We want to divide 488604 by 40.

Going ahead to step 1:
4 divided by 40 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 40

Let's proceed to step 2:
40 goes into 48 1 times with a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 40 from 48 and we're left with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 40

Going ahead to step 3:
40 can be fit into 88 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 80 from 88 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 40

Let's proceed to step 4:
86 divided by 40 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 122.0
If we subtract 80 from 86, we get 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 40

Moving on to step 5:
When dividing 60 by 40, we get 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1221.0
If we subtract 40 from 60, we get 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 40

Going ahead to step 6:
204 divided by 40 is 5 with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 12215.0
If we take 200 away from 204, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
40 can be fit into 40 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 12215.1
Deduct 40 from 40 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:
0 divided by 40 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12215.1
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.

Going ahead to step 9:
If we divide 0 by 40, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12215.1
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.

Our division results in 12215.1 with a remaining 0.0.
