Let's divide 388579 by 40
Our goal is to divide 388579 by 40.

Advancing to step 1:
If we divide 3 by 40, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 40

Moving on to step 2:
38 divided by 40 is 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Include the next digit (8) from the dividend after 38, then repeat: 388 / 40

Moving on to step 3:
40 goes into 388 9 times with a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 360 from 388 and we're left with 28.
Include the next digit (5) from the dividend after 28, then repeat: 285 / 40

Going ahead to step 4:
40 can be fit into 285 7 times, resulting in a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 97.0
The remainder is 5 after subtracting 280 from 285.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 40

Let's proceed to step 5:
57 divided by 40 is 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 971.0
Subtracting 40 from 57 leaves us with 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 40

On to step 6:
40 goes into 179 4 times with a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 9714.0
The remainder is 19 after subtracting 160 from 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
40 can be fit into 190 4 times, resulting in a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 9714.4
Subtracting 160 from 190 leaves us 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.

On to step 8:
When dividing 300 by 40, we get 7 with a remainder of 20.
The next digit of our result is 7. 
Result so far: 9714.47
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.

Advancing to step 9:
If we divide 200 by 40, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 9714.475
Subtract 200 from 200 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.

Step 10:
The number 40 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 9714.475
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
0 divided by 40 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9714.475
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 outcome is 9714.475, with a leftover of 0.0.
