388435 divided by 40 
Our goal is to divide 388435 by 40.

Step 1:
The number 40 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 40

Going ahead to step 2:
40 can be fit into 38 0 times, resulting in a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Fetch the next digit (8) from the dividend, attach it to 38 and continue: 388 / 40

Advancing to step 3:
40 goes into 388 9 times with a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 360 from 388, we get 28.
Append the next digit (4) from the dividend to 28 and continue with: 284 / 40

Let's proceed to step 4:
40 can be fit into 284 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 97.0
If we take 280 away from 284, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 40

Step 5:
The number 40 fits into 43 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 971.0
Deduct 40 from 43 and we're left with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 40

Moving on to step 6:
The number 40 fits into 35 0 times, leaving a remainder of 35.
The next digit of our result is 0. 
Result so far: 9710.0
Subtract 0 from 35 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
40 can be fit into 350 8 times, resulting in a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 9710.8
If we take 320 away from 350, we end up 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.

Advancing to step 8:
If we divide 300 by 40, we get 7 and a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 9710.87
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.

Let's proceed to step 9:
200 divided by 40 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 9710.875
Subtracting 200 from 200 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.

Advancing to step 10:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9710.875
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.

Moving on to step 11:
When dividing 0 by 40, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9710.875
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.

In conclusion, the division gives 9710.875 with a balance of 0.0.
