We divide 230902 by 40
Our goal is to divide 230902 by 40.

Moving on to step 1:
The number 40 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 40

On to step 2:
23 divided by 40 is 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 40

On to step 3:
40 goes into 230 5 times with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 200 from 230 and we're left with 30.
Grab the next digit (9) from the dividend, add it to 30, then carry on: 309 / 40

Moving on to step 4:
309 divided by 40 is 7 with a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
Subtracting 280 from 309 leaves us with 29.
Append the next digit (0) from the dividend to 29 and continue with: 290 / 40

Step 5:
40 can be fit into 290 7 times, resulting in a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 577.0
The remainder is 10 after subtracting 280 from 290.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 40

Step 6:
The number 40 fits into 102 2 times, leaving a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 5772.0
The remainder is 22 after subtracting 80 from 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
If we divide 220 by 40, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 5772.5
If we take 200 away from 220, we end up 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.

Let's proceed to step 8:
If we divide 200 by 40, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5772.55
Deduct 200 from 200 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.

The quotient of the division is 5772.55, and the remainder is 0.0.
