We're dividing 481888 by 40 
Our goal is to divide 481888 by 40.

Step 1:
The number 40 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 40

On to step 2:
When dividing 48 by 40, we get 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 40 from 48 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 40

Moving on to step 3:
40 goes into 81 2 times with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 80 from 81 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 40

Step 4:
The number 40 fits into 18 0 times, leaving a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
If we subtract 0 from 18, we get 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 40

Going ahead to step 5:
40 can be fit into 188 4 times, resulting in a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 1204.0
If we subtract 160 from 188, we get 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 40

Let's proceed to step 6:
If we divide 288 by 40, we get 7 and a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 12047.0
The remainder is 8 after subtracting 280 from 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
80 divided by 40 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 12047.2
If we subtract 80 from 80, 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.

Going ahead to step 8:
When dividing 0 by 40, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12047.2
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.

Advancing to step 9:
0 divided by 40 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12047.2
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.

The final result is 12047.2 with a remainder of 0.0.
