Let's divide 144831 by 40
Our goal is to divide 144831 by 40.

Advancing to step 1:
The number 40 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 40

Advancing to step 2:
40 can be fit into 14 0 times, resulting in a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Grab the next digit (4) from the dividend, add it to 14, then carry on: 144 / 40

On to step 3:
40 goes into 144 3 times with a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 120 away from 144, we end up with 24.
Grab the next digit (8) from the dividend, add it to 24, then carry on: 248 / 40

Advancing to step 4:
40 goes into 248 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
Subtracting 240 from 248 leaves us with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 40

Step 5:
40 goes into 83 2 times with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 362.0
Deduct 80 from 83 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 40

Moving on to step 6:
When dividing 31 by 40, we get 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 3620.0
The remainder is 31 after subtracting 0 from 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
40 can be fit into 310 7 times, resulting in a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 3620.7
Deduct 280 from 310 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
When dividing 300 by 40, we get 7 with a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 3620.77
Subtracting 280 from 300 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 3620.77 with a remainder of 0.02.
