383984 ÷ 40 
We want to figure out the number of times 383984 can be divided by 40.

Moving on to step 1:
The number 40 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 40

Going ahead to step 2:
40 goes into 38 0 times with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Take the next digit (3) from the dividend and append it to 38, then repeat: 383 / 40

Moving on to step 3:
If we divide 383 by 40, we get 9 and a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 360 away from 383, we end up with 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 40

Going ahead to step 4:
239 divided by 40 is 5 with a remainder of 39.
Write down 5 as next digit of the result. 
Result so far: 95.0
The remainder is 39 after subtracting 200 from 239.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 40

Advancing to step 5:
40 goes into 398 9 times with a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 959.0
Subtract 360 from 398 to get 38.
Take the next digit (4) from the dividend and append it to 38, then repeat: 384 / 40

Step 6:
If we divide 384 by 40, we get 9 and a remainder of 24.
The next digit of our result is 9. 
Result so far: 9599.0
The remainder is 24 after subtracting 360 from 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
If we divide 240 by 40, we get 6 and a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 9599.6
Deduct 240 from 240 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.

Step 8:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9599.6
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.

Step 9:
40 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9599.6
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 quotient of the division is 9599.6, and the remainder is 0.0.
